How to change the oil in a DSG box. How to change the oil in a DSG box Friction clutch wear

Transmission DSG7 (Direct Shift Gearbox - Direct Shift Gearbox) This type of Automatic Transmission (AT) with "dry" clutches, which was developed by VW, in which there are seven gears and a gear reversing. Switching occurs without interruption of the power flow (switching occurs without switching on the neutral) this is the main advantage of Automatic Transmissions, and also provides a "creeping" mode at the beginning of the movement. Therefore, DSG boxes are automatic transmissions.

The flagship in the production of "dry" clutches is VW, they immediately took into account the design flaw of the DSG6 to include forward and reverse gears with one clutch, and released a seven-speed transmission, where different rows are included forward and reverse.

They are equipped with DSG7 mainly in cars with a small engine capacity; on powerful engines with high torque, “dry” clutches do not withstand. Completed with DSG7 are mainly Volkswagen, Skoda, as well as Audi, Seat.

Car models where you can find the DSG7 box

A feature of the DSG7 is the presence of two volumes of oil, for the mechatronics that controls the DSG7 and the mechanical gearbox (where the forks, gears, etc.). If, on a conventional mechanical gearbox, the clutch is clamped by design springs installed during manufacture, and when the clutch pedal is pressed, the clutch “dissolves” and thus the moment is not transmitted, then in the DSG7 the opposite happens, until the mechatronics gives the clutch signal “dissolved”, they rotate freely , the mechatronics gives a signal, and the piston acts on the fork and the fork clamps the disc, and if there are no pressure leaks in the mechatronics, then the disc is clamped with the necessary force.

The diagnostic tools contain the temperature value of the first and second friction disc, the temperature is calculated, i.e. how the clutch slipped, how long, what moment was on the engine or what pressure was in the mechatronics, based on these readings, the clutch temperature is calculated - this is an unmeasured temperature - this is the calculated temperature. If the design temperature starts to rise, then the clutch begins to slip excessively and the DSG7 box will need to be repaired in the future.

Ford, Mercedes, Fiat have developed their DSG boxes with dry clutches. Ford abandoned hydraulics, installing electric motors, which are controlled by an electronic unit combined with electric motors mounted on a box. Adaptation of the DSG7 Ford after replacing the electronic unit or dual clutch is carried out automatically, unlike VW where it is required to carry out the adaptation procedure, with special equipment.

The clutch in this box is a separate non-separable (non-repairable) unit. When replacing the clutch, the DSG7 is supplied by the manufacturer as an assembly, with adjusted disc gaps.

Classic DSG7 issues

The appearance of defects in work of the DSG 7, often associated with incorrect operation of mechatronics

• No forward and reverse gears
• Jerks when shifting gears.

After the diagnostics, the DSG7 mechatronics repair or its reprogramming is required. The reasons may be in pressure leaks along internal cavities, or the gear shift software not working properly. Which causes the clutch to slip. DSG7 reprogramming is also required to update the software and optimize the box.

It is possible that the mechatronics unit overheats in the driving modes of the car (providing a crawling mode) and, as a result, slipping of the clutch discs, further repair of the DSG7, which is an operational defect in the operation of the DSG7. The manufacturer recommended actions for DSG7 owners to force the box to switch from “D” mode to “N” mode when the car is in a traffic jam and has been standing for more than 1 minute. VW developers did not count on the Russian features of the DSG7 operating conditions (many hours, regular traffic in traffic jams).

Also, the failure of the DSG7 mechatronics is an oil leak from the “breather”, replacement or repair is required. If the electrical circuits inside the unit fail, the DSG7 mechatronics assembly is replaced.

Care must be taken to protect exposed parts of the DSG7 from contamination. The failure of “dry” discs is possible for various reasons: Oil on the clutch (for example, due to leakage of the engine crankshaft oil seal), water, clogging of the clutch with dirt, etc. is a problem with the DSG7 box with dry clutches.

The mechanical part of the DSG7 at high mileage is characterized by breakdowns of conventional mechanical gearboxes - gear failure, pitting of bearings, shafts, destruction of drive forks, etc. Then a thorough repair of the mechanical part of the box is required.

Replacing DSG6 with DSG7 is not possible, because transmissions are aggregated with different engines.

In 2011 in the production of the DSG7, individual components were modified, improvements were made, the mounting dimensions for the clutches were changed, the release bearing drive lever was changed.

Owners of cars with DSG7 are faced with automatic transmission problems

• jolts when shifting forward or reverse,
• switching shocks,
• vibration AKP,
• shift slips,
• the car goes into emergency mode.

The average operating mileage of a car with DSG7 is 90-150 thousand km. Repair and replacement of the clutch is carried out using a special tool. Holding DSG repair 7, it is required to strictly observe the assembly and adjustment technology, in accordance with the requirements of the manufacturer.

Oil change in DSG box 7, it is possible to produce only in the gear reducer. Replacement can be made on average after 40 thousand mileage or as needed, because. the manufacturer fills in oil for the entire service life.

Released software updates are a benefit of the DSG7. At the first sign of improper operation of the DSG7, you should start with diagnostics and, if necessary, “flash” the mechatronics if they are released by the manufacturer for your car, but we do not recommend “flashing” the DSG7 that is working properly.

Diagnostics and advice on the DSG7 box

ATG service engineers provide technical support in the form of consultations on technical matters related to the repair and operation of DSG7. You can get prompt advice by calling or sending a request from the company's website

When diagnosing DSG7, many operating parameters can be checked, considered as specialized test devices. Deciphering and analyzing the received codes for the operation of the box allows you to find the cause of the malfunction of the automatic transmission and prevents damage to the DSG7 by detecting defects in a timely manner. One of the points of diagnosing the DSG7 is to control the temperature of the clutch in operating modes. Clutch wear can be viewed programmatically.

Checking for leaks, changing the oil, it is possible to carry out at the ATG service center and is a necessary procedure aimed at maintaining the automatic transmission in working order. technical condition in order to increase its uptime.

ATG has special tools and equipment and can carry out all restoration work. We have experience in competent, qualified maintenance and repair of automatic transmission DSG7 in Moscow.

DSG is a special kind of transmission. This mechanism combines the principles of operation of automatic and technology, and the preselective mechanism itself is found on cars of the VAG group. The main advantage of such a box is that it runs very smoothly. At the same time, power is not lost, which has a positive effect on efficiency. Many car owners are interested in how the DSG-6 oil is changed, because the mechanism is quite complicated.

Advantages

When using this transmission, the gear change is not felt at all. The owners claim that driving at such a checkpoint is comparable to a CVT. There are no shocks when switching, which are characteristic of mechanics and automatic. And this is definitely a plus.

But the positive aspects of the transmission do not end there. Another significant advantage of the DSG system is economy. VAG specialists conducted a series of tests, as a result of which it turned out that the savings with these boxes is about one and a half liters of fuel per 100 kilometers, which is quite significant. And this despite the fact that power unit was the same on the DSG and simple automatic box gears.

The 6-speed DSG is internally marked DQ-250. Unlike the seven-speed analogues, it has a serious design feature. The clutch here works in an oil bath. Therefore, the transmission is called "wet". It is impossible to burn such a clutch, as on a seven-speed DSG. But at the same time, more oil is needed to operate the box than for more modern seven-speed systems.

This advantage requires the owner to regularly change the oil on the DSG-6. But 7-speed units operate in dry conditions - here the clutch is not immersed in the bath. Therefore, an oil change according to factory regulations is not necessary.

Device and principle of operation

In general, this is ordinary mechanics, but the gears are switched on by a robotic mechanism without power loss. This DSG is different from traditional mechanics. In a manual transmission, torque is interrupted when the clutch is depressed. When the torque is removed, the fuel is wasted just like that. DSG gearboxes add dynamics and efficiency to cars.

The main thing that distinguishes these boxes from any other is the two clutches. But in reality it's even more difficult. There are also two boxes. They are in the same building. If two gearboxes are used, then there are also two input shafts, with a separate clutch for each.

Gears for odd gears are installed on one shaft along with the rear. On the second, even gears are fixed. After the car starts in first gear, second is already on and ready to switch. When the electronics decide it's time to change gear, the clutch of the input shaft will disengage, and the second will quickly pick up the torque without any loss in power.

The gears are switched on by ordinary synchronizers. The forks are driven by hydraulic cylinders. The clutch is also engaged and disengaged by the hydraulic system. Manages all this mechatronics. This is the main electronic and hydraulic assembly. The shaft of even gears is made hollow. Inside it is a shaft of odd speeds. This is how VAG engineers managed to install two manual gearboxes in one housing.

Typical "diseases"

It is necessary to change the DSG-6 oil strictly according to the manufacturer's regulations - they can be seen in the instructions for the machine. Almost all typical breakdowns occur due to an untimely change of transmission fluids.

The multi-disk wears out very often. Most often, this manifests itself in the periodic absence of reverse gear loading and in jerks when shifting even gears. The gearbox can go into emergency modes. In this case, it is impossible to include odd gears. DSG repair in this case is the replacement of the entire friction clutch or the replacement of individual discs. Next, the basic setup and adaptation is performed.

Also, one of the problems of these boxes is the wear of the solenoids that regulate the pressure in mechatronics. In this case, you can feel jerks when switching. Breakdown does not cause errors. You can solve the problem by replacing the solenoids. Also performed complete replacement mechatronics in some cases.

There may be certain problems with the mechatronics electronic unit. They are usually detected during a cold start of the engine. The DSG-6 box will go into emergency mode once. Sometimes for the same reason, the checkpoint may periodically go into emergency mode. You can restore the work by replacing the mechatronics or repairing the unit.

Often craftsmen diagnose wear and other bearings. Differentials also fail. This is manifested by increased noise during movement, braking, acceleration. You can solve the problem overhaul DSG using quality used spare parts.

When to change the oil?

Change the oil yourself

To change the gear oil, you will need six liters of VAG G052182A2 fluid, oil filter, drain plug sealing ring.

Some drivers, when changing oil to DSG-6, prefer not to use VAG products, but transmission oil Pentosin FFI-2. It has a lower price, all the necessary tolerances and guarantees stable operation of the dual clutch gearbox. The main thing is never, under any circumstances, mix this product with VAGovsky.

Process steps

First of all, the car is raised on a lift or installed on a pit. recommended for parking. Next, unscrew the drain plug on the gearbox housing. First, a liter of liquid will pour out of the box. Then you need to unscrew the control tube - about five more liters will pour out from there. If chips leak out with the oil, then this is a reason to contact the service to repair the box.

The next step is to replace the filter. On many cars (including Skoda) with DSG-6, the filter is higher. To gain access to it, you need to remove the battery along with the platform, the air filter housing and air ducts. Then you can unscrew the filter.

Filling in new oil

Then you should fill in the DSG-6 preselective gearbox with new fluid. Some pour it directly into the filter hole. But it is very long. It is best to find a special adapter that is screwed in instead of an oil filler plug, and two meters of hose. A funnel is pulled over the hose from above and the product is poured.

According to the manufacturer, the box should include about seven liters. But in reality there are only five. Next, the engine is started, and the funnel is kept where it was. Then the box switches to different modes. After that, check the level.

The funnel is taken out, and a bottle of oil is put in its place. The bottle must be placed on the floor. Excess oil will drain into it. When the liquid stops flowing, but only drips, the adapter can be unscrewed.

Examination

This completes the DSG-6 oil change. The oil filler plug is screwed on, the box is parked, and the engine is not turned off. Special equipment from VAG will help determine the oil temperature. Next, unscrew the plug and see if oil drips. If this is so, then he is allowed to drain. If not, then add more and repeat the procedure.

Since the invention of the automobile, designers have constantly tried to improve and automate the gearbox. Individual automakers offered their own options for automatic transmissions. So, the German concern Volkswagen has developed and brought to the market a robotic box DSG.

Features of the device and operation of the DSG box

DSG (Direct Shift Gearbox) literally translates as a direct shift gearbox and is not considered an automatic in the strict sense of the word. It would be more correct to call it a dual-clutch preselective gearbox or a robot. Such a box consists of the same elements as a mechanical one, but the functions of gear shifting and clutch control are transferred to electronics. From the point of view of the DSG driver, the box is automatic with the ability to switch to manual mode. In the latter case, the gear change is performed by a special steering column switch or the same gearbox lever.

For the first time, the DSG box appeared on Porsche racing cars in the 80s of the last century. The debut turned out to be successful - in terms of gear shifting speed, it surpassed traditional mechanics. The main disadvantages, such as high cost and unreliability, were overcome over time, and DSG boxes began to be massively installed on mass-produced cars.

Volkswagen was the main promoter of robotic gearboxes, installing such a gearbox on the VW Golf 4 in 2003. The first version of the robot is called the DSG-6 by the number of gear stages.

Device and characteristics of the DSG-6 box

The main difference between a DSG box and a mechanical one is the presence of a special unit (mechatronics) that performs the function of shifting gears for the driver.

Mechatronics includes:

• electronic control unit;
• electrohydraulic mechanism.

The electronic unit reads and processes information from the sensors and sends commands to the actuator, which is the electrohydraulic unit.

As hydraulic fluid a special oil is used, the volume of which in the box reaches 7 liters. The same oil is used to lubricate and cool clutches, gears, shafts, bearings and synchronizers. During operation, the oil is heated to a temperature of 135 ° C, so a cooling radiator is integrated into the DSG oil circuit.

The hydraulic mechanism, with the help of electromagnetic valves and hydraulic cylinders, sets in motion the elements of the mechanical part of the gearbox. The mechanical scheme of the DSG is implemented using a double clutch and two gear shafts.

Double clutch is technically implemented as a single block of two multi-plate clutches. The outer clutch is connected to the input shaft of the odd gears, and the inner clutch is connected to the input shaft of the even gears. The primary shafts are installed coaxially, with one partially located inside the other.

The dual-mass flywheel transmits engine torque to the clutch, to which the gear corresponding to the crankshaft speed at the moment is connected. In this case, the mechatronic immediately selects the next gear on the second clutch. Having received information from the sensors, the electronic control unit decides to switch to another gear. At this point, the second clutch closes on the dual-mass flywheel and an instantaneous speed change occurs.

The main advantage of the DSG box over the hydromechanical machine is the gear shift speed. This allows the car to accelerate even faster than when using a manual transmission. At the same time, due to the selection of the correct transmission modes by the electronics, fuel consumption is reduced. According to representatives of the concern, fuel savings reach 10%.

Features of the DSG-7 box

During the operation of the DSG-6, it was found that it is not suitable for engines with a torque of less than 250 Nm. The use of such a box with weak engines led to a loss of power when shifting gears and an increase in fuel consumption. Therefore, since 2007, Volkswagen began to install a seven-speed gearbox option on budget cars.

Principle of operation new version The DSG of the box has not changed. Its main difference from the DSG-6 is dry clutch. As a result, the oil in the box became three times less, which, in turn, led to a decrease in its weight and size. If the weight of the DSG-6 is 93 kg, then the DSG-7 already weighs 77 kg.

In addition to the DSG-7 with dry clutch, for engines with torque exceeding 350 Nm, Volkswagen has developed a seven-speed gearbox with an oil circuit. This box is used on cars of the VW Transporter and VW Tiguan 2 family.

Diagnosis of malfunctions of the DSG box

The novelty of the design is the main reason for the appearance of problems in the operation of the DSG box. Experts identify the following signs of its malfunction:

• jerks when moving;
• switching to emergency mode (the indicator lights up on the display, you can continue driving only in one or two gears);
• extraneous noise in the gearbox area;
• sudden blocking of the gear lever;
• oil leak from the box.

The same symptoms may indicate different problems. So, jerks while driving can be caused by malfunctions of both mechatronics and the clutch. Emergency mode indication does not always lead to restrictions in the operation of the gearbox. Sometimes it disappears after restarting the engine or disconnecting the battery. However, this does not mean that the problem has disappeared. Blocking of the selector lever can be caused by freezing of the drive cable, any mechanical damage or breakage.

The most problematic elements of the DSG box are:

• mechatronics;
• dual mass flywheel;
• multi-plate clutch;
• mechanical shaft bearings.

In any case, if you suspect a malfunction of the DSG box, you should immediately contact service center Volkswagen.

Self-service DSG box

On the issue of the possibility of self-maintenance and repair of the DSG box, to date, there has not been a consensus. Some car owners believe that when problems arise, it is necessary to change the assemblies. Others try to disassemble the box and fix the problem with their own hands. This behavior is explained by the high cost of DSG box repair services. Moreover, often experts attribute malfunctions to design features and try to avoid work, especially if the car is under warranty.

Self-troubleshooting in the DSG box requires high qualifications and the availability of funds computer diagnostics. The large weight of the assembly requires the participation of at least two people and strict adherence to safety regulations.

As an example of a relatively simple DSG repair, consider a step-by-step mechatronics replacement algorithm.

Replacing mechatronics DSG box

Before replacing the mechatronics, it is necessary to move the rods to the dismantling position. This procedure will greatly facilitate the further dismantling process. This can be done using the Delphi DS150E diagnostic scanner.

To work, you will need the following tools:

• a set of torexes;
• a set of hexagons;
• tool for fixing the clutch blades;
• set of wrenches.

The dismantling of mechatronics is carried out in the following order:

1. Place the car on a lift (overpass, pit).
2. Remove engine protection.
3. In the engine compartment, remove the battery, air filter, necessary pipes and harnesses.
4. Drain the oil from the gearbox.
5. Disconnect the holder of the wiring harness with connectors.
6. Loosen the screws securing the mechatronics.
7. Remove the clutch block from the box.
8. Disconnect the connector from the mechatronics board.
9. Gently pull towards you and remove the mechatronics.

Installation of a new mechatronics is carried out in the reverse order.

Self-changing oil in a DSG box

DSG-6 and DSG-7 boxes need regular oil changes. However, for DSG-7, the manufacturer does not provide for this procedure - this node is considered unattended. Nevertheless, experts recommend changing the oil at least every 60 thousand kilometers.

You can change the oil yourself. This will save up to 20-30% on maintenance costs. It is most convenient to perform the procedure on a lift or viewing hole (flyover).

The procedure for changing the oil in the DSG-7 box

To change the oil in the DSG-7 box, you will need:

• internal hex key 10;
• funnel for filling oil;
• a syringe with a hose at the end;
• container for draining used oil;
• drain plug;
• two liters of gear oil that meets the standard 052 529 A2.

Warm oil will drain faster from the gearbox. Therefore, before starting work, the transmission should be warmed up (the easiest way is to make a short trip). Then you should release access to the top of the box in the engine compartment. Depending on the model, you will need to remove the battery, air filter and a number of pipes and wires.

To change the oil in the DSG-7 box, you must:

The procedure for changing the oil in the DSG-6 box

About 6 liters of transmission fluid are poured into the DSG-6 box. Oil change is carried out in the following sequence:

1. Place the car on a lift, overpass or viewing hole.
2. Remove engine protection.
3. Place a container under the drain plug to drain the used oil.
4. Unscrew the drain plug and drain the first part (about 1 liter) of oil.
5. Unscrew the control tube from the drain hole and drain the main part of the oil (about 5 liters).
6. Screw in a new drain plug.
7. To access the upper part of the gearbox, remove the battery, air filter, necessary harnesses and pipes.
8. Remove oil filter.
9. Pour 6 liters of gear oil through the filler neck.
10. Install a new oil filter and screw on the cap.
11. Start the engine and let it run for 3-5 minutes. At this time, switch the gear lever to each position for 3-5 seconds.
12. Unscrew the drain plug and check for oil leaks from the drain hole.
13. If there is no oil leakage from the drain hole, continue filling.
14. If an oil leak occurs, tighten the drain plug and install engine protection.
15. Start the engine, make sure there are no errors on the dashboard.
16. Carry out a test drive to verify that the transmission is working properly.

Reviews of motorists about DSG boxes

Since the advent of the DSG box, its design has been constantly improved. However robotic boxes still remain rather capricious knots. Volkswagen Group periodically conducts a mass recall of cars with DSG transmission. The manufacturer's warranty on the boxes either increases to 5 years, or decreases again. All this testifies to the manufacturer's incomplete confidence in the reliability of DSG boxes. Oil is added to the fire and negative reviews from owners of cars with problematic boxes.

Review: Car Volkswagen Golf 6 - hatchback - The car is not bad, but the DSG-7 requires constant attention

Pluses: Frisky engine, good sound and insulation, comfortable lounge. Cons: Unreliable automatic transmission. I had the honor of owning this car in 2010, 1.6 engine, DSG-7 gearbox. Pleasantly pleased consumption … In mixed mode, the city highway was 7l / 100km. Also pleased with the noise isolation and the quality of regular sound. Good throttle response in the city and on the highway. The box, if necessary, quick overtaking, does not slow down. But at the same time in the same box and the main problems !!! With a run of 80,000 km. the box began to twitch when switching from 1 to 2 in traffic jams ... As many have already said, this is a flaw in this box, like the previous DSG-6 ... I'm still lucky, many people have problems much earlier ... So, gentlemen and ladies, when buying this brand car, be sure to pay attention to this moment !!! And always on a hot engine! Since it only appears when the box is warmed up !!! Time of use: 8 months Year of manufacture of the car: 2010 Engine type: Gasoline injection Engine size: 1600 cm³ Gearbox: automatic Drive type: Front Ground clearance: 160 mm Airbags: at least 4 General impression: The car is not bad, but DSG-7 requires constant attention!

Review: Car Volkswagen Passat B7 sedan - Does not live up to expectations about German quality

Pros: Comfortable. Accelerates quickly due to the turbine. Quite economical in terms of fuel consumption

Cons: No quality, very expensive repairs

It so happened that since 2012, a VW Passat B7 car has been at the disposal of our family. Automatic transmission (dsg 7), the highest grade. So! Of course, the car made the first impression, and a very good one, since there were no foreign cars of this class in the family yet. But the impression was short-lived. The first step was to compare the complete set of the car with other automakers. For example, the Camry's driver's seat is electrically adjustable, but here everything has to be done by hand. More about the quality of the cabin. The plastic is terrible and ugly, compared to the French or the Japanese. The leather on the steering wheel rubs very quickly. The leather of the front seats (as they are used more often) also cracks very quickly. The radio freezes frequently. Rear view camera included, the image just freezes. This is what first of all catches the eye. The doors began to open tighter and creak terribly after a couple of years, and it is not possible to fix this with an ordinary fairy tale. The box is a different story. After 40 thousand run the car just got up! When visiting an authorized dealer, it was found that the box is completely replaceable. A new box costs about 350 thousand, plus the cost of labor. Wait a month for the box. But we were lucky, the car was still under warranty, so the replacement of the box was completely free. However, the surprise is not very pleasant. After replacing the box there were still problems. At 80 thousand kilometers, I had to change the double clutch disc. There was no guarantee and I had to pay. Also out of trouble - the liquid in the tank froze. The computer gave an error and blocked the supply of liquid to the glass. It was fixed only by a trip to the service. Also, the inhabitant of the headlights consumes a lot of liquid, you can fill the whole bottle of 5 liters, it will be enough for a day of traveling around the city in bad weather. Fixed it by simply turning off the headlight washer. The windshield was heated. A pebble flew off, a crack went. I don't deny that windshield suffers very often and it can be considered a consumable, but for a replacement official dealer requested 80 thousand. Expensive for a consumable though. Also, from the sun, the plastic on the door melted and curled up into an accordion. In this case, the question arises - where is the German quality and what do they take such money for? Very disappointing. Time of use: 5 years Cost: 1,650,000 rubles. Year of manufacture of the car: 2012 Engine type: Petrol injection Engine displacement: 1798 cm³ Gearbox: robot Drive type: Front Ground clearance: 155 mm Airbags: at least 4 Trunk volume: 565 l Overall impression: Does not live up to expectations of German quality

However, there are also owners who are completely satisfied with their car with a DSG gearbox.

Experience: a year or more Cost: 600,000 rubles I bought my faithful assistant "Plus" in 2013, after the sale of vv passat b6. I thought I would be disappointed, because the car was two classes lower. But to my surprise, I liked the plus one even more .Very unusual was the location of the driver behind the wheel. You sit like in a “bus”. The suspension is very “knocked down”, it never broke through. I was pleased with a large number of airbags (already 10 pieces) and 8 very worthy-sounding audio speakers. The car is really made of metal. When you close the door, it feels like a “tank hatch”, which gives additional confidence for safety. The 1.6 petrol engine is paired with 7 dsg mortars. An average consumption of 10 liters in the city. I read a lot about the unreliability of dsg boxes, but for the 5th year the car has been in the family, and there are no complaints about the operation of the box (there were light pokes from the very beginning). .In maintenance is not more expensive than any foreign car (unless you go crazy and not be repaired by the officials). The disadvantages would include a not quite economical engine (after all, 10 liters for 1.6 is a bit too much), and I would like a larger washer reservoir. In general, as a summary, I want to say that this is a faithful and reliable friend. I recommend it to all families! Posted on 23 January, 2018 - 16:56 review by ivan1977 5

SEAT Leon Copa Plus car. Bundle 1.8TSI+DSG7+ABS+ESP+EBD.

Robotic gearbox DSG-7, DQ200, 0AM, NTQ. We purchase original VAG transmission oil, order code - G052512A2. The gearbox drain plug is unscrewed with a regular hexagon by 10.

Photo-1: DSG-7 in section.

If you could damage it, then the cork code is N10037105. Both elements are taken from the catalog by VIN number.

How to change the oil we spied on Alexander Will Willis from Drive2.ru. He has everything clearly explained and shown. A couple of additions from us. If you have never removed the air filter housing, then check in advance how this is done. At 1.8 TSI, to remove it, you need to gently pull up, because. it sits tightly on two landing pins of the battery platform, and there are rubber dampers in the mounting holes of the filter housing. And one moment. We drained 1.7 liters of used oil from the DSG7 box, and filled in all 2 liters.

The oil change in the DSG-7 was made on a run of 76,000 km. What made us do it? Doubts! Doubts that in the constantly contacting parts of the gearbox, the technical fluid can work through the entire life of the car and retain its performance characteristics. 2 warranty years - yes, transmission oil is able to work out. So what is next? And if the machine is used for 5-7 years? We think not. The gearbox oil is not able to work without losing its physical and chemical characteristics for such a long time. Therefore, they made a replacement. The result of the work is below.

	Photo-2: metal particles in used oil from DSG7. Mileage 76 thousand km.		Photo-3: again metal particles in used oil from DSG7.
	Photo-4: used oil color from DSG. The bottle stands in front of the sun's rays and does not shine through. The photo was taken without a flash.		Photo-5: comparison of fresh and used DSG7 oil for color. Photo taken with flash.
	Photo-6:comparison of fresh and used DSG7 oil for color. Photo taken without flash

According to subjective feelings, we did the oil change procedure not in vain. The box began to switch very softly, barely noticeable.

19.07.2016 After changing the oil in the gearbox, 4 months have passed and 6000 km have been rolled. There were no problems during this time: there were no smudges, fogging, due to pouring 2 liters of oil. The car accelerated 1 time to 200 km. at one o'clock.

Our conclusion: the oil in the mechanical part of the DSG-7 needs to be changed. How often? We believe that once every 60 thousand km.

It’s good when the car is new and you don’t have to think about where and when to service your iron horse. Another thing is when you bought a used car with an expired warranty, it is clear that there is no point in continuing to service the car from an authorized dealer. In today's article, we will talk in detail about how to independently change the oil in a DSG-7 box in a Volkswagen Passat CC (there is practically no difference between replacing the restyled and derestyling versions, at least the process itself is completely similar). We will also consider the choice of oil, which the official dealer recommends filling in the oil and which oil is best suited as an analogue so that you can save a little.

Owners of the bu Volkswagen Passat ss 1.8 with dsg-7 often have the question of whether they need to change the oil in the box or not? The controversy arises from the fact that the DSG-7 uses a dry clutch, which is why many people mistakenly think that the oil in the box is completely empty and therefore there is nothing to change. Let's dispel this myth.

How much oil is in a DSG-7 DQ 200 box?

The second most popular question, which logically follows from the first, is how much oil do you need to change? After studying a huge number of forums where owners share their experiences, we came to a figure of 2.1 liters.
