How to choose a used BMW X5 E70 in good condition. All owner reviews about BMW X5 E70 restyling Brakes, suspension and steering

The second generation of the BMW X5 crossover (E70 body) was on sale from 2006 to 2013. During this time, the model experienced one update, which came in 2010. In Russia, the car in its pre-restyling era was offered in four modifications - two diesel and two petrol. Both turbodiesels of the M57 series, which are in-line sixes, had the same volume of 2993 cc. see, but different power output settings - 231 and 286 hp. Gasoline units represented by a six-cylinder engine 3.0 272 hp. and V-shaped “eight” 4.8 355 hp. were deprived of turbocharging. The top-end engine was equipped with systems for continuously variable valve timing and variable valve lift height. All engines worked in conjunction with a 6-speed automatic transmission.

Restyling in 2010 significantly influenced specifications crossover, as a serious adjustment was made to the engine line and the gearbox was replaced. Diesel engines from the pre-reform vehicle remained in service, but were modernized. The three-liter “six” operating in the BMW X5 30d modification was added 14 hp. power and 20 Nm of torque (up to 245 hp and 540 Nm, respectively). The top diesel from the 40d version also improved both indicators, increasing maximum output to 306 hp. and 600 Nm.

More noticeable changes have occurred in the range of gasoline engines. The previous “aspirated” engines gave way to turbocharged units - a 3.0-liter six-cylinder engine of the N55 series with a power of 306 hp. (modification of the BMW X5 35i) and a 4.4-liter V8 from the N63 family, producing up to 407 hp. (BMW X5 50i). The installation of turbo engines added agility to the crossover, allowing the most powerful gasoline version to “throw off” a whole second from its previous acceleration to 100 km/h (it was 6.5 s, now it is 5.5 s). A significant contribution to the improvement dynamic characteristics The restyled BMW X5 E70 was equipped with a new 8-speed automatic transmission ZF, which replaced the 6-speed gearbox.

The equipment revised during the update also affected fuel consumption. Diesels began to consume an average of about 7.5 liters (previously it was almost 9 liters). The gasoline 306-horsepower turbo engine also turned out to be more economical than its predecessor - 10.1 liters versus 11.7 liters.

BMW X5 E70 (2006 – 2010)

BMW X5 E70 restyling (2010 – 2013)

BMW X5M E70 is the most striking and colorful example of the fact that the BMW company produces not only powerful, bright and competitive cars, but also cars of fairly high quality.

The BMW X5M took on the niche of the first with dignity, and coped with this task perfectly. It was initially positioned as a sports car and was first presented in April 2009 at the International Auto Show in New York.

The X5 M’s belonging to the class of sports models is confirmed by the presence of characteristic “gills” on the front side wings, as well as the 20-inch alloy wheels installed on it. The car also received a special exhaust system with dual tailpipes, which was typical for M Series models.

The interior, in turn, was made in the traditional M-style down to the smallest detail. Indicative instruments and a tachometer were perfectly combined on the instrument panel, pleasing to the eye and significantly increasing driving comfort - a variable warning zone, as well as a specific, functional and white display backlight. In addition to everything, the sports crossover received heated seats, a climate control program and electrically adjustable seats with a memory function.

Engine

The first X5 M in the E70 body was equipped with direct fuel supply systems and twin turbocharged Twin Scroll Twin Turbo, which made it possible to squeeze out 555 hp.

The “High Precision Injection” direct fuel injection system has been improved, which has significantly reduced the amount of CO2 emissions into the atmosphere, and, as a result, the car fully complies with environmental standards.

Transmission

With the help of the 6-speed Steptronic automatic transmission, it is now possible to support manual gear shifting. Especially for this, “steering wheel paddles” were located on the steering wheel.

Dynamics

* - with “MDriver’s” package maximum speed X5M crossover is limited to 275 km/h

acceleration to 200 km/h takes 16.9 seconds

Dimensions

Equipment

Despite the excellent dynamics, the X5M E70 also offers high level efficiency in its segment thanks to a combination of EfficientDynamics technologies, brake energy regeneration, electric fuel pump and removable A/C compressor.

The software system has also proven itself very well. The general parameters and characteristics of the system allow you to take full control of the drive system and chassis, as well as effectively distribute the traction force between the right and left rear wheels, which in turn allows you to increase vehicle stability and control accuracy.

M X5 E70 equipped with regulator ground clearance rear axle and air suspension. A special system for controlling the stiffness of shock absorbers and suspension was also installed. The updated steering characteristics deserve special attention. The special Servotronic system significantly enhances the steering drive (depending on the speed of travel), which significantly increases steering precision even at high speeds.

BMW introduced a replacement for the M E71 in 2015 -.

The second generation BMW X5 (serial designation E70) replaced its predecessor on the American continent in November 2006, and in Europe at the beginning of 2007. The Bavarian crossover, like the previous X5, was assembled for all markets without exception in the USA - in Spartanburg, South Carolina. In 2010, the X5 underwent restyling, during which the front and rear lighting equipment, front bumper and fenders were changed. Corrections were also made to the line power units, and instead of a 6-speed automatic transmission transmissions began to be installed at 8-speed.

Fans of the Bavarian crossover, who have traveled hundreds of thousands of kilometers on the first E53, claim that the second generation turned out to be much more successful. Owners of the E70 note a higher level of comfort and better endurance and reliability. But don’t delude yourself, having gotten rid of a number of old “sores” of the E53, the new E70 has acquired its own.

Engines

Initially, the second generation BMW X5 was equipped with naturally aspirated gasoline engines: in-line six N52 3.0si (272 hp) and V8 N62 4.8i (355 hp). As well as a diesel inline six-cylinder M57 unit with a displacement of 3.0 liters in two versions: 3.0d (235 hp) and 3.0sd - with two turbochargers (286 hp). Since 2008, the 3.0sd diesel engine (286 hp) began to be designated 35d, and in 2009 another modification, 35d, with a power of 265 hp appeared.

After restyling in April 2010, turbocharged engines began to be installed instead of naturally aspirated gasoline engines: 3-liter N55 35i (306 hp) and 8-cylinder V8 4.4 liters with two turbines N63 50i (407 hp) . Diesel engines have also changed. Now they were represented by the 3-liter N57 in the following versions: 30d (245 hp), the previous 35d (265 hp), the new 3-liter with 2 turbines 40d (306 hp) and from 2011 M50d (381 hp).

A peculiarity of 3-liter gasoline engines assembled before November 2008 is the knocking of hydraulic compensators when cold or after several short runs without complete warming up. In such cases, BMW prescribed replacement of the cylinder head assembly. A cheaper way is to replace only the hydraulic compensators. But in both the first and second cases, the knocking soon appeared again.

A 3-liter naturally aspirated engine periodically requires replacing the crankcase ventilation valve (CVVV), built into the valve cover. The reason is that the crankcase gas outlet channels become clogged, which in winter can lead to them freezing and squeezing out the oil. The predecessor had the same problem. Despite the improvements, it was not possible to completely get rid of the shortcoming. But the service life of the KVKG has increased to 50-60 thousand km. The cost of a new cover at dealers is about 15-20 thousand rubles, in auto parts stores - about 3-5 thousand rubles. On this motor There are problems with the VANOS gas distribution system with a mileage of more than 100-120 thousand km. When the system valves jam, the engine begins to stall after starting, fuel consumption and sometimes oil consumption increases. The price of “treatment” is 11-16 thousand rubles.

On vehicles with the 35i engine, there have been several cases of the need to replace a failed engine ECU. A new unit costs about 100 thousand rubles.

The naturally aspirated 4.8i is perhaps the most reliable in the E70 engine line. With a mileage of more than 80-100 thousand km, oil consumption may increase due to hardened valve stem seals. By this time, the crankshaft oil seals may also leak.

The twin-turbo 50i receives large thermal loads due to turbochargers in the camber of the block. Oil consumption of 1-2 liters per 1,000 km after 50-60 thousand km is a common phenomenon. Seizures in the cylinders and wear of the turbines also occur (oil begins to leak). The similar engine in the BMW X5M is practically free of these problems - thanks to better cooling of the engine oil and the engine itself, due to larger radiators.

Diesel units require replacing the fuel filter at least once every 40,000 km, but more often is better. The cost of a new original filter is about 1,600 rubles, an analogue one is about 900 rubles. The particulate filter runs for more than 100-120 thousand km. Replacement with a new one from dealers will cost 100,000 rubles. A more budget-friendly way is to cut out the old filter and reflash the engine ECU.

Air filter diesel engine For correct installation requires certain skills. Many auto mechanics, not having them, neglect the replacement technology - they roughly “shove” the filter into its place. As a result, the base of the filter is destroyed, and the air, bypassing it, directly enters the engine. This significantly reduces the life of the motor. With the arrival of frost, diesel BMW X5s begin to have difficulty starting. In the vast majority of cases, the fault for this lies solely with the “sagging” battery.

At 3.0d there is a failure of the turbine vacuum valve, and at 3.0sd there is a failure of the turbine pressure converter. Owners of BMW X5 engines with a diesel 35d note the presence of extraneous noise (resembling the noise of a belt or roller) that appears during intense acceleration in the speed range of 2500-3000 rpm. This noise does not progress and is not a sign of a malfunction. The sound only annoys the owners.

The engines also have common weak spots. Among them is a roller bolt that breaks off drive belt mounted units on vehicles assembled in 2008-2009. Cars with potential possible malfunction fell under the BMW recall campaign. With a mileage of more than 60-100 thousand km, the radiator often leaks (about 8 thousand rubles). A little later, after 100-120 thousand km, most likely, you will have to replace the electric pump. Dealers will ask about 25-30 thousand rubles for a replacement. In the online spare parts store, you can purchase a similar one for 8,000 rubles.

A cracked engine sump is a disease of the BMW X5 E70. In most cases, the reason is the tightening torque of the drain bolt is exceeded. To replace the pan, you must hang the engine. New pallet in official services costs about 25,000 rubles, and replacement work will require about 18,000 rubles.

Transmission

For those who like to “anneal”, the servomotor of the transfer case often fails at 80-100 thousand km. The assembled transfer case costs about 120,000 rubles, the servomotor costs about 30,000 rubles. On pre-restyling E70s, they often fail rear gearbox- with a mileage of more than 80-120 thousand km. The cost of a new gearbox is about 90-100 thousand rubles.

On the pre-restyling 6-speed automatic transmission from ZF, the mechatronics adapter often “breaks” in cold weather. In this case, the car does not drive, and the driving modes are reset to “P” (parking). The fragile plastic walls of the adapter cannot withstand the pressure of thickened oil. The cost of a new adapter is small: 1500 rubles from dealers and only 300-500 rubles in a spare parts store. Since June 2008, the adapter has received thicker walls, and this problem does not arise.

After the 100,000 km mark, shocks may appear after stopping or when changing gears - from 1st to 2nd or from 3rd to 4th. There are several ways to solve the problem. First you need to change the oil followed by adaptation of the box. If the shocks remain, you can reflash the box ECU. In rare cases, it comes to expensive replacement of mechatronics.

With a mileage of more than 100-150 thousand km, the automatic transmission pan may leak. The cost of a new one in official services is about 18,000 rubles, in online spare parts stores it is cheaper - about 3-8 thousand rubles. The pan can also crack if the drain plug is overtightened. By this time, the automatic transmission sealing sleeve may become “snotty” (600 rubles).

Chassis

The second generation X5 suspension is considered stronger than its predecessor. The main consumables are levers and rods with a service life of about 80-120 thousand km. The E70 was optionally equipped with rear air suspension, and for versions with three rows of seats it is required. The service life of pneumatic elements (pillows) is about 60-100 thousand km. The cost of one air spring is about 8-9 thousand rubles. Wheel bearings last more than 50-80 thousand km.

BMW X5 equipped with the Active Drive system (optional) has high stability and controllability. Active stabilizers play a significant role in this. On E70s assembled before April 2008, the active front stabilizer began to rattle loudly with the onset of cold weather. Cost of a new one front stabilizer from dealers about 70-80 thousand rubles, in the online spare parts store - about 40,000 rubles.

Body and interior

Over time, streaks appear and the edges around the windows become cloudy. A set of new edgings costs about 70,000 rubles, but after a while dots and streaks appear on them again.

Headlight washer covers can be torn off at high speed. This happens especially often in winter, when the cold weather “squeezes” the washer nozzle out of the bumper, and it cannot return to its original state. The cost of a new unpainted cap is about 900 rubles, and assembled with a nozzle - about 2,000 rubles.

Panoramic glass often breaks, and the mechanism that drives it jams. Water in the cabin may appear due to clogged drains under the windshield or in the panorama. A clogged drain under the master brake cylinder can lead to water flooding of the engine ECU with all the ensuing financial consequences (about 100,000 rubles). The rear window washer line dries out over time and loses its elasticity, which very coldy may cause pipe rupture in the center of the console, under the driver's seat, or in the left rear fender. It is better to replace the leaking line with a VAZ analogue.

The interior, contrary to expectations, often disappoints with its “cheap” squeak. Owners are often forced to resort to gluing plastic elements of interior decoration with noise-vibration-absorbing materials. In addition, you have to wrap the trunk lid lock brackets and rear seat hinges with electrical tape. The trunk shelf also makes extraneous sounds. When warming up a cold interior, the air ducts may crackle.

On BMW X5 older than 5 years, the varnish on the decorative wood-look inserts is cracking. Little things that cause bewilderment are the erasing icons of the climate control buttons, cracks and destruction of the buttons for turning on the seat ventilation, and the abrasion of the rubberized layer on the steering wheel spokes (on pre-Restayle). Over time, the top lining of the glove compartment lid peels off, preventing it from opening.

Electrics

On pre-restyling BMW X5, the rear light seals often leak, which leads to oxidation and corrosion of the electrical contacts on the board. The cost of a new flashlight is about 3-5 thousand rubles. There are also questions about the front optics. Headlight glasses crack, and through the cracks moisture gets into the ignition units, causing them to fail. In addition, over time, the headlight reflector becomes cloudy, burns out and crumbles.

There are frequent cases of software “glitches” of the handbrake unit. In this case, the car sets the parking brake and does not release it. The cost of a used unit is about 10,000 rubles, the cost of repairs is about 8,000 rubles. Dealers replace a faulty unit for 30-35 thousand rubles.

There are cases short circuit heating the seats and burning the driver's seat cushion trim.

The climate control system sometimes starts to malfunction. It is possible to “bring the system back to life” after resetting the terminal. Due to deformation of the plastic partition and the microfilter housing, “water from the street” can get to the contacts of the damper servomotor. As a result, the contacts become oxidized and the dampers can no longer be controlled. Servo drive functionality is restored after cleaning the contacts. Dealers replace the servo drive for 3-4 thousand rubles.

The health of the “electrical” part of the E70 largely depends on the condition battery. Due to the large number of consumers, it can be discharged after 2-3 years of operation. The consequences become obvious with the arrival of frost. Dealers are ready to provide a new original gel battery worth about 20-25 thousand rubles; an analogue is available in a spare parts store for 5-8 thousand rubles. New battery it is necessary to “register”, otherwise there will be problems with charging it. The cost of such a procedure at dealers is about 3-5 thousand rubles, in third-party specialized services - about 500-1500 rubles.

Conclusion

BMW X5 of the second generation dashed off Russian roads enough. As a rule, engines and gearbox (except for the ill-fated adapter) do not require outside intervention. Small design flaws that you wouldn’t expect from such an eminent manufacturer are very disappointing. And what about the creaking of the interior, like some Chinese car! But, despite everything, fans of the BMW X5 remain faithful to their car and are ready to invest money in it again and again, forgiving minor whims.

BMW X5 E70 is the second generation of the popular crossover from BMW. On secondary market Now this car is the leader among luxury crossovers in Russia. Although the price of the car is quite high. The cost of maintaining such a car is high, but what comfort, driving emotions, excellent dynamics, handling and brand. All this is worth the money spent.

The BMW X5 E70 continued the success of its predecessor E53. The E70 has become much better: comfort has improved and appearance has changed significantly. The car also began to save fuel. Diesel configurations consume only 10-11 liters in the city, and 8 on the highway. This is a large crossover with serious power and excellent dynamics. Many people dream of this car, regardless of age and gender. But the car has some nuances that it is advisable to take into account before buying such a car. The BMW X5 E70 has undergone restyling, so the cars before and after restyling are really different.

Pre-styling car

In terms of design, the car remained the same as in the E53 of recent years of production. The engines remained the same four-wheel drive And ride quality not changed.

The main changes have been made to the body and interior; there is more space inside; you can find configurations with a third row of seats. The dimensions of the car have become slightly larger and the external design has become more stylish and modern. And in technically nothing new at all, and after restyling, when turbo engines appeared, the technical characteristics began to change. Handling has been improved. If the E53 was already good in handling, then the E70 became even better.

The E70 handles in much the same way as a BMW 5 Series, although the high center of gravity and greater weight didn't hurt. Of course, there is more roll than in the five, and the suspension is stiffer. The car doesn’t have much off-road qualities left, because the bumpers are low, so it’s better not to drive off-road, why? expensive car destroy. Although the ground clearance is quite large - 220 mm. There is a rigid clutch lock on the front axle. But, since such cars usually have 18 or 19-inch wheels with road tires, in serious mud these tires will quickly become washed out and the wheels will simply slip.

Salon

The most pleasing thing about the car is the interior, it is very comfortable, there is a new, for those times, multimedia system with an “iDrive” washer. The car is very roomy, you can put a lot of cargo in it, or seat 7 people. You can drive comfortably in the 5th, and load the trunk with things.

Post-restyling car

Restyling was done in 2010, turbocharged engines began to be installed under the hood, and after 2011, a new 8-speed automatic transmission began to be installed in gasoline versions.

The car has become much faster; if we take the 3-liter turbo engine for comparison, then its dynamics are the same as those of the pre-restyling 4.8-liter V8. And the new V8 engines with a steel turbine will accelerate to hundreds in 6 seconds. And the top version of the X5M E70 accelerates to hundreds in 5 seconds. Gasoline versions still consume a lot of gasoline, but less than pre-restyling cars. For example, BMW X5 xDrive50i with a 4.4 engine and a power of 407 hp. With. In the city it consumes 17.5, and on the highway 9.5 liters per 100 km.

Weak points in the car

After 5 years of operation, cars from early years of production began to cause problems for their owners: many components began to fail, and this leads to high costs during maintenance. Cars with simple aspirated engines begin to eat oil after 5 years.

After 5 years of operation, owners usually sell the car and buy a post-restyling one with a turbocharged engine. And all serious problems already fall on the future owners of these cars. Usually, while the car is under warranty, nothing happens to it, and problems begin after 5 years of operation. And since the design is complex, repairs are expensive.

Dealers try to find a non-warranty case in each of the breakdowns, the fact that the car eats oil, they say that this design features BMW engines, and when jerks appear in the automatic transmission, they update the software of the transmission control unit.

Therefore, those who buy an E70 from recent years of production need not worry too much; it will drive for some time without problems. But those who have decided to buy an older car, and an inexpensive one at that, should think carefully about whether it is worth doing. Now we will talk about the most common problems with these cars.

Body

The body is strong, but it is expensive to repair. The body uses a considerable number of decorative elements, the panels fit neatly, and there are beautiful front fenders that go into the bumper. All these design moves increase the cost of repairs if some kind of collision occurs with something, but this is all nonsense, we will assume that there will be no collisions.

There is a lot of plastic in the lower part of the car, which will immediately begin to break off if you drive off-road or along curbs. But the most important thing is that there is no rust in these cars yet, since the E70 has excellent anti-corrosion protection for the body.

Even on cars after an accident there are no traces (blown paint) of poor quality body repair, front bumper and fenders are plastic. In general, there are damaged cars on the market, despite the fact that they have parking sensors and an all-round visibility system. The car provokes inexperienced drivers to drive fast, and there are also various safety systems that add extra confidence to the driver. But a damaged car can always be easily identified when purchasing.

After some years of operation, the windshield drains may become clogged; they need to be cleaned periodically; on the right side, under the windshield drain, there is an electronic control unit, so cleaning it is not particularly convenient. Hood seals can also become leaky over time, allowing water to get under the hood. The hatch drain may still become clogged, but this is not careful operation when the car for a long time stands and leaves fall on her. If you drive it normally and keep it in the garage, then nothing bad will happen to it.

There are still many little things that can make themselves felt, for example, tail lights may lose their tightness, after which the silver inserts will begin to oxidize and the taillight electronics will begin to fail.

It also happens that the hood cables break if there is not enough lubrication and the mechanism jams. But the car is great passive safety, if an accident occurs, then all passengers have a high chance that they will survive. Well, it’s better not to get into an accident, because it will be expensive to restore the car later; if more than 10 airbags go off, then all the panels will have to be changed, not to mention the body repair. Therefore, you need to make sure that the car is not damaged or damaged, because successfully restoring a car after an accident is simply very expensive.

Questions about the cabin

The older the car is, the more often minor troubles begin to appear: wooden inserts can come off, especially on pre-restyling cars this often happens. The door handles are quite soft, so they scratch easily. But the steering wheel and seats will remain in good condition for a long time.

If the windows are opened frequently, then after many years they will begin to tap, which means that the rollers need to be changed. You also need to check the condition of the hose through which the liquid passes to the rear window; if a leak appears in the hose, the driver’s carpet will become wet, and this moisture will also begin to get on the contacts in the electrics, so you need to make sure that moisture does not accumulate anywhere.

There are times when the FRM unit responsible for the car’s lighting fails. To fix this, you can try to reflash or repair the unit; if that doesn’t help, then you’ll have to buy a new one. The climate control fan may break down after about 5 years of operation. The wipers may fail, since their motor is quite weak and can cut off the gears. There may also be malfunctions in the multimedia system; iDrive has to be updated frequently.

Electrics

Over time, more electrical problems appear. Stabilizers lateral stability here regulated, also here active steering, adaptive headlights. In general, there is a lot of electrics, and everywhere there are electric valves, gearboxes, electric motors that eventually require repair or replacement. Also, due to salts and other nasty things, the wiring under the bottom or under the bumpers can deteriorate. Also, backlight sensors, headlights, and brakes require revision. Everything doesn’t fail at the same time, then one thing breaks, then something else. In general, this is a common situation for cars with considerable age and mileage.

Brakes

The brake system in the BMW X5 E70 is simply excellent, it has a good service life, the pads last about 40,000 km, and the discs - 80,000 km. No problems with ABS or pipe rust were identified, if something happens to braking system, then this can be easily and inexpensively fixed.

Suspension

Both the front and rear suspensions last quite a long time, especially if you don’t specifically drive the car through potholes and other off-road conditions. Most cars have adaptive suspension, air suspension on the rear axle and electronically controlled shock absorbers. Sometimes you can find a car with a sports suspension, it does not have electronics. The levers and silent blocks are strong and replacing them will not cost a lot of money. 100,000 km. The front and rear suspensions will easily serve.

But electronics and pneumatics are quite expensive to maintain, but thanks to all these new technologies, a 2-ton car drives almost like a sports car. But over time, when the standard suspension with its electronics fails, you can install a conventional suspension, it will be simpler and cheaper.

Steering

There are 2 types of steering in a car:

• A conventional rack and pinion mechanism is simple and reliable, with an adjustable spool. It lasts a long time, rarely leaks, it starts knocking after many years, the electronics here also last a long time.
• Adaptive control is a more complex mechanism, so problems appear more quickly here. The rack itself is expensive here, and its servo drive fails over time, and sensor failures also occur. But when driving, the car has a sharp steering wheel, and it is also easy to park with such steering.

Many failures can be corrected by flashing, but it happens that you have to change all the components. Therefore, it is advisable to install the latest version of the software for the control unit, and also, the steering control should be serviced only by a high-quality service.

Transmission

Everything is fine with the transmissions in the E70, nothing unexpected should happen. Sometimes the gear motor that connects the front axle. But some problems may also arise with the automatic transmission after 200,000 km. mileage Cardan shafts last a long time, but you need to take care of them; sometimes you can change the oil in them.

There are cases that on cars with low-power diesel engines, the gearbox may fail, especially if chip tuning is done beforehand. This can also happen with some supercharged petrol V6s. But in more powerful configurations there is a reinforced gearbox, so it rarely fails.

Also, before purchasing, you need to check the condition of the drive joints; if there is little lubrication in them, then knocking noises will begin to appear in the drives. The gearboxes in the BMW X5 E70 are 6-speed ZF 6HP26/6HP28, which last a long time if you change the oil and do not move away abruptly; you also need to change the gas turbine linings sometimes.

At the time of purchase, you can check the box like this: if there are jerks or twitches during acceleration, but there are no errors in the transmission, then this means that the gas turbine engine lock will soon break, and the automatic transmission itself is still normal, but if the car jerks when switching, then this is This means that the automatic transmission will soon need repairs.

Perhaps the whole issue is wear and tear or there is a leak in the sump and the oil level has dropped. If the bushings in the box have already worn out and dirt has appeared in the valve body, then even if you add oil, this will not save you. Therefore, it is advisable to prevent such minor problems in the box that will later lead to major problems. There are also new eight-speed automatic transmissions, they appear on services quite rarely, sometimes it happens after a mileage of 100,000 km. The clutches are already quite worn out and the mechatronics unit is clogged.

Motors

New BMW engines use plastic in very critical places. Also, motors, as usual, do not like overheating, they have a complex control system, and the sensors must also be in order. There will be a lot of hassle with the engine, especially if you don’t clean the radiator and rely on the warranty. A BMW is a car that needs to be looked after and periodically invested in.

3-liter 6-cylinder engine N52B30 – enough good motor, but it operates at high temperatures, and according to the regulations, the maintenance interval is quite long. And the oil here, according to the regulations, is Castrol, it is not of sufficient quality, so they lie piston rings After only 3 years of active use, this is why oil consumption appears. To avoid such nonsense, it is better to fill in higher quality oil such as Motul or Mobil and change it every 10,000, or better yet, every 7,000 km.

If oil consumption has already begun, then you can get rid of it only by rebuilding the engine or somehow decoking it. Some BMW owners they install cooler thermostats on the car, and also improve the fan control system. Such upgrades can prevent oil consumption.

In addition, there are other problematic components - Valvetronic throttleless intake, VANOS phase shifters, oil pump circuits. Timing chains with a fairly long resource, but it varies from 120 to 250 thousand km. Therefore, you need to monitor them so that they do not stretch at the wrong time. There is also a more powerful V8 engine with a volume of 4.8 liters - N62B48, it is also successful, but still, it has the same weak points as the V6, only the V8 heats up even more and it has 8 cylinders, so In case of breakdown there will be more costs.

And besides this, the design of the timing belt here is not so successful - instead of a roller in the center, there is a long damper. Therefore, the timing chain life here is approximately 100,000 km. And, working temperature should not exceed the norm. Here, too, it is better to come up with solutions to reduce the operating temperature of the motor. And fill in with better quality oil.

After restyling, cars with direct injection and turbocharging appeared. All the problems with N-series engines remain, but new ones have also appeared. It's not so simple with injectors; sometimes they fail. Before purchasing, you should definitely check the injectors, because they are expensive, especially on V8 engines, they are difficult to change.

It can also cause problems and fuel pump Bosch. So, there are more problems with direct injection. But there are also advantages to engines with direct injection - they are less sensitive to detonation and have lower fuel consumption. But there is also a turbine here, which also often fails.

M version

The most charged configuration of the X5M is equipped with the S63B44 motor, which is built on the basis of the N63B44. This is a 4.4 engine, the turbines are located here in a special way - in the camber of the cylinder block. This arrangement gave fast warm-up catalysts and access to turbines has become better. The main thing is not to overheat the engine, because then there will be a lot of problems.

From high temperature plastic parts quickly fail after 3 years of driving. Parts of the cooling system and wiring often fail. This concerned the N63B44 motor, but the M-motor has fewer problems because its operating temperature is lower. Valve stem seals They hold oil better and the catalyst lasts longer.

But since the engine has high technical characteristics, turbines may fail, control systems may malfunction, and intake manifolds Can't stand plastic. There are more direct injection injectors here - 8 pieces. The timing chains are quite thin; they can easily stretch or break when worn. Everyone needs to keep an eye on this.

In general, gasoline engines are not as good as we would like, the operating temperature is high and there is a lot of plastic in the design, we need to somehow correct this situation - lower the operating temperature.

Diesel engines

But the diesel engines for the X5 E70 are much better made. Pre-restyling cars also have a reliable M57 engine; in recent years, this engine has been considered one of the best. Timing chains last from 160 to 250 thousand km. depending on use. On cars with 2 turbines, it often happens that oil leaks from the tubes that go to the turbines.

The particulate filter can also cause difficulties; it is not cheap and it is not easy to remove it from the car. But a diesel engine does not use oil, the piston engine lasts a long time, and there are also no problems with vanos and valvetronic. It has good traction, you can even do chip tuning and the power will really increase.

The power of diesel engines varies: from 235 to 286 hp. With. Engines with 2 turbines are more complex, but compared to gasoline engines, diesel engines will require less money for maintenance. The main thing is to fill with high-quality fuel and change the oil and filters on time. After restyling, new N57 diesel engines began to be installed, but in terms of reliability they did not become any worse.

Which BMW X5 should you choose?

A BMW X5 in the E70 body can still be found in good condition, especially if the previous owner did not kill the car on purpose and looked after it better than according to regulations, then you can take cars with N52, N55, M62 engines, but it is best to take cars with diesel engines , their condition is usually better, and in the future they will require less costs. There may also be costs for suspension and electrical components, but any work on the car is best done in a specialized service center.

The main thing is not to buy a car with an N63 engine, yes, it is powerful and gives excellent dynamics, but there is a lot of hassle with it. You also need to forget about the regulated maintenance interval, this will protect the car from breakdowns. The oil must be changed every 7,000 - 10,000 km. Fill in quality synthetic oil, and not the low-viscosity oil that the manufacturer recommends. The oil in the gearbox must be changed every 30,000 km, and the condition of the suspension must be checked every time. And then the car will still travel.

Foreign cars up to 600 thousand rubles can please you with their efficiency

In general, the topics “Where to look when buying an X5” or “I want to buy”, etc. appear quite often. Sometimes they write in private (I don’t mind. I’m happy to help. That’s exactly why I decided to create a topic).

Based on this, I decided to write it in a general topic (some points relate to diesel), so that I could immediately indicate it if such questions arise. I summarized from memory what I read on the forum and from personal experience.

If you have anything to add, then just Welcome!

1. Crankshaft damper. Changed didn't change? Its real service life is difficult to determine, because... the mileage is 50%, or maybe more. Failure: complete separation from the crankshaft.

2. Generator bolt. Changed at one time due to a recall company. Find out when there was a regular fix and then figure out if it’s a new model or not.
Failure: a bolt breaks, the generator moves, the belt falls off.

3. Knock in the active stabilizer. Corrections began in 2008.

4. Look at the plastic casing that runs along the body along the windshield under the hood. It looks like this \_/. It shouldn't leak. Until 2010 they were of the old type. It is very important.
Failure: It dries out and begins to let water (rain) onto the plastic engine protection (plate) from above. Next, the water seeps under the plastic protection of the engine and enters the channel where the injectors are located. There is no way out for the water from there.
Failure: The injectors rust and over time a short circuit occurs. The engine is switched off while driving by the car itself. Those. the engine stalls while driving. Then it may start, but stall again. If you don't change it for a long time, it won't start again. Injectors are expensive. Previously they cost 21,000 for one.
Check injectors for overflow and adjustment.

5. Check how the generator is charging. There are problems with the regulator.

6. When turning the ignition on and off, the car should not shake. Those. turn it off and it may seem as if it shook, as if it was sausage. This shouldn't happen. A serviceable car will turn off and start smoothly. (Only true for cars with electronic throttle. Euro3 without throttle and damping harshly.)

7. There should be no vibration in the cabin. It may be subtle on the steering wheel and door handles. There should not be a strong hum in the cabin at idle. In general, behind closed doors, you should have the feeling that it’s working. Gas engine. Those. If you didn't know it was a diesel, you wouldn't have guessed it.

8. The start-stop button should not be worn out. Those. All letters should be clearly visible on it. The button begins to wear out around 150,000 miles. It's barely noticeable. Severely worn out by 200,000.
The remaining buttons (PDC, DCS, etc.) should also be like new.
The headlight switch button may be erased at the bottom left, because... When landing, some people touch it with their knee.

9. Look for oil leaks on the left and right of the engine. Oil can fly out through loose swirl flaps. There may be a leak from here.
Failure: The valve comes off and flies into the cylinder. Engine capital. Therefore, they are removed and plugs are installed.

10. If not particulate filter, and according to my feelings, it becomes clogged somewhere around 200,000 miles; when you press the gas pedal sharply, there may be black smoke in the exhaust.
In general, if there is soot, then the pipes inside the exhaust are clean. Not black.

11. Look at Windshield. BMW doesn't have it very well good quality and if there is a strong temperature difference, for example, where there is snow in the wiper zones, and you suddenly turned on the oven to heat the glass, it can crack parallel to the body in the wiper zone.
Also check whether the glass is original or not.

12. Turn on and check the parking sensors. The picture on the monitor should be smooth, and not torn along the picture where the front and back of the car are. Parking sensors should not catch "ghosts"

13. If a triangle lights up on the instrument panel, then switch modes on the left lever and see what the machine wrote. A triangle means that the car warned from some minor messages such as fill the washer fluid, to breakdowns that have not been eliminated.

14. Inspect the box for smudges. They have a plastic tray that can degrade over time due to constant heating. It's not scary. You just need to change the pan and oil. About 23,000 - 25,000 for everything.
The leak may also be due to the plastic bushing of the box (the wires go there. Sometimes it also leaks due to old age).
By the way, during this run I would change the oil in the automatic transmission, gearboxes and transfer case. And check when to change the brake fluid, coolant, fuel filter, air filter(every second oil change) and cabin filter.
Over time, the so-called “glasses” in the automatic transmission dry out and burst. The box stops shifting.

15. The gearbox should shift very smoothly. You don't even have to notice when this happens. If it kicks, you can try changing the oil and resetting the adaptation. But I would immediately refuse this car.

16. Check the operation of the climate control. It should blow everywhere from all nozzles at the same temperature with the same temperature set on the climate and with a uniform flow in strength.

17. Inspect the rear lights. Due to ill-conceived sealing, the taillights on the trunk lid sweat and, as a result, the contacts melt. Only replace the lights if they don't light up. And if they burn and sweat, then replace the sealant.

18. The rings in the headlights should all burn evenly.

19. There should be no smell of washer fluid in the cabin. Often the washer hose that runs through the cabin bursts and it begins to flow directly into the cabin. Signs: it ends quickly, there is a smell in the cabin, water may be (depending on where the hose burst) under the front passenger's floor trim (you need to put your hand deep), water may be under the rear left passenger's trim, water may be in the trunk compartment under the trim )
Repair: dismantling the entire interior and drying it out. Dealers seem to make them for 30,000 rubles.

20. There should be no water near the battery or in the trunk niches. This occurs due to poor-quality fastening of the rubber band on the wires at the top of the trunk door or due to the rubber plug at the bottom of the trunk for interior ventilation.

21. The hatch must operate and open to all intended positions. Check it and it’s better not to touch it again.

22. Check for fogging and leaks on the gearboxes.

23. Check the operation of the main thermostat and the EGR system thermostat (if equipped).

24. Check the glow plug computer and the glow plugs themselves.

25. There is a possibility of a circuit break. There are only three chains. Tears one of them. Because The mileage may vary on a car, but the pattern of mileage and breakdown has not yet been established.

26. Front springs: may burst over time. Can only be found on a lift. The damage does not manifest itself in any way while driving.

27. Over time, the headlights become covered with small cracks along the lower edge.

28. If squeaks begin to occur in the windshield wiper trapezoid, then only replace it.

29. For diesel engines from America. It is necessary to check American diesel engines (3.5d) for the condition of the exhaust gas cooler - soot in the front of the engine, the smell of exhaust in the cabin - and whether a recommendation has been made to replace the mounting of this very cooler. Otherwise, sooner or later it will crack.
