Changing the oil in the DSG-7 gearbox type 0CW (DQ200)

I was not faced with the question of whether to change or not to change, of course, to change because the vaunted VAG engineers are not yet able to cancel chemistry and physics. For information from the official Liqui Moly website:

Storage of motor oils (synthetic, semi-synthetic) and transmission oils for no more than 3 years (do not confuse shelf life and expiration date).
And it is used in our carabasses and is also subjected to heating. !Attention! 1.
VAG claims that the oil in the box is filled for its entire service life and is changed only when the box is repaired.
2.
The DSG-7 has two oil circuits:
-
transmission oil circuit (here we will change the oil)
-
hydraulic circuit (aka Mechatronic)
3.
Use only
VAG G 052512A2
. The use of other oils leads to malfunctions or failure of the gearbox. Ideally, you need to change the oil in all two circuits, but in Mechatronics, changing the oil yourself is painful and problematic.

There are 2 ways to change the oil:

1. Remove the battery, battery platform, rocker, breather cover, pour oil through a watering can. 2. Lightly remove the breather cap, insert the tube and pump in the oil with a syringe.

So, to change the oil in the DSG-7 in the 2nd way you will need:
-
a 10mm hex to unscrew the gearbox plug

—

2 clean plastic bottles

The algorithm of actions is as follows.

Before changing the oil, the box must be warmed up
-
remove the plastic protection

The DSG gearbox type 0CW (DQ200) has two separate oil fills. One is for gear oil and the other is for hydraulic oil. The oil level in the 0CW gearbox and the hydraulic oil level in the mechatronics cannot be checked. The correct oil level can only be achieved by draining the old oil and adding new oil!

Transmission oil

The 7-speed dual clutch transmission DSG - 0CW has two separate oil fills.
One for the transmission oil area - arrow A
-, and the other for the hydraulic oil area -
arrow B
-.

For the 7-speed dual clutch transmission, only use replacement gear oil and 0CW hydraulic oil, see Electronic Catalog of Original Parts. Gearbox oil level - arrow A

- and the hydraulic oil level in the mechatronics -
arrow B
- cannot be checked. The correct oil level can only be achieved by draining the old oil and adding new oil.

The gear oil for the 0CW 7-speed dual clutch gearbox is permanently filled (oils are designed to last a lifetime). For this reason, the oil level is not checked and there is no oil level plug on this gearbox.

If there is a leak in the gearbox, the cause must be determined and the problem repaired. The correct oil level in the gearbox can only be achieved by draining the old oil and then refilling the gearbox with new oil in the specified quantity. See DSG 0CW filling quantities.

Draining transmission oil

— Raise the car. — Place a tray under the gearbox. — Unscrew the oil drain plug on the gearbox (arrow).

— Drain the oil. — Install the oil drain plug.

Refilling with transmission oil

The prescribed amount of oil must be strictly observed - the gearbox will only be filled correctly if this has been done.
Overfilling as well as underfilling impairs the proper operation of the gearbox. Read also: Nissan Qashqai brake pads reviews
New oil is filled through the air release hole. If the transmission is on the vehicle, depending on the model and engine, the air filter or battery with battery tray must be removed when filling the transmission with oil.

— Remove the air filter — Remove the battery and battery tray — Remove the air vent cover.

— Install the VAS 6262/4 adapter onto the VAS 6262A adapter.

Before screwing the adapter VAS 6262A onto the oil distributor, measure the length of the tube (dimension -a-) and, if necessary, shorten the adapter tube to size -a-: 210 mm. Dimension -a- is measured from the shaft (green area in the picture) of the oil filling adapter VAS 6262A.

Note: Shake the oil bottle before opening to mix any deposits on the bottom of the bottle with the oil. For filling, use only gear oil for 7-speed dual-clutch gearbox DSG - 0CW, see Electronic Catalog of Original Parts.

— Screw the oil bottle onto the adapter VAS 6262 A.

If the thread of the oil distributor does not match the thread of the adapter VAS 6262 A, the adapter VAS 6262/6 must be used.

— Remove the adapter from the gearbox after refueling. — Wipe the area around the air outlet with a cloth. — Install on the ventilation cover. — Install the battery tray and battery — Install the air filter.

Tightening torques, see below. Note. Replace the bolts/nuts that are tightened at an angle and also replace the necessary components after removal.

Note: There is a risk of damage to the mechatronics of the double clutch transmission J743. For mechatronics, only hydraulic oil available in spare parts may be used, see Electronic Catalog of Original Spare Parts. Other hydraulic oils will cause problems and/or failure of the gearbox. The hydraulic oil level cannot be checked.

If hydraulic oil is lost from the mechatronics, the correct oil level can only be established by changing the oil. During installation work, the mechatronics must be hermetically sealed. Insufficient hydraulic oil and overfilling affect the operation of the mechatronics and can lead to malfunctions.

Condition: Mechatronics must be removed

Draining hydraulic oil

Remove oil filler screw -arrow-. Replace the filler screw after removal.

— Remove the ventilation cover - arrow - if this has not already been done.

The mechatronics ventilation cover is destroyed when removed and must be replaced, see the electronic catalog of original spare parts. When the mechatronics is turned, oil drains from both the oil hole and the vent hole. For this reason, the mechatronics should be positioned so that both openings are above the oil drain pan. Switch on the mechatronics and allow the hydraulic oil to drain completely.

Filling with hydraulic oil

Fill in new hydraulic oil only after completing all mechatronics repair work. After completely draining the hydraulic oil, return the mechatronics to its original position. The filler hole is directed upwards.

If you have not found information on your car, look at the cars built on the platform of your car. Most likely, the information on repair and maintenance will be suitable for your car.

Owners of cars with a DSG-7 robotic gearbox with a double dry clutch are concerned about the question: does this transmission require maintenance? According to the manufacturer's regulations, the box is maintenance-free. This means that the oil filled at the factory can not be changed during the entire service life, which the manufacturer limits to a mileage of 100,000 km.

To change or not to change the oil

However, real experience in operating the DSG-7 DQ200 in our country proves that replacement is necessary.

• Firstly, the harsh climatic conditions of many regions of Russia significantly reduce the service life of the oil.
• Secondly, in European countries people change cars much more often, while our car enthusiasts, when making such a purchase, expect a longer service life.

Car service workers confirm in practice the need for an oil change. Technical fluid drained from the box after 50-60 thousand kilometers has a dark tint and loses its original properties. Consequently, she can no longer cope with her tasks 100%.

If you purchased a used car with an automatic transmission, it is recommended to immediately replace the transmission fluid. After all, you cannot know for sure when the previous owner changed the oil, in what mode he operated the car, or what brand of transmission fluid he used.

Of course, you can operate the gearbox without servicing, and change the oil during repairs, but for those who want to extend the service life of the “robot”, it is better to go to a car service center every 40-60 thousand km and change the transmission fluid. There are no official recommendations regarding the maximum mileage without maintenance, so you should rely on the experience of technicians and car owners.

What types of DSG-7 are there?

1. DSG7-0B5 (DL501) – 7-speed robot with wet clutch. It is installed on cars with a longitudinal internal combustion engine, as well as front-wheel drive or all-wheel drive.
2. DSG7-0BT/0BH (DQ500) is a 7-speed preselective gearbox with a wet clutch, designed for installation in cars with a transverse internal combustion engine, as well as front-wheel drive or all-wheel drive. Suitable for engines with torque up to 600 N/m
3. DSG7-0AM/0CW (DQ200) - a 7-speed robot with a dry clutch, which is installed on inexpensive VW cars with front-wheel drive and low-power 1.2-1.4 liter engines with a torque of up to 250 N/m

Oil selection

You should know that different transmission fluids are poured into the mechatronics control unit and into the box itself. The mechatronics need 1 liter, and the gearbox needs about 2 liters of oil. Use only transmission fluids recommended by the manufacturer, otherwise you can significantly reduce the life of the transmission.

For mechatronics, VAG G 004 000 M2 oil is recommended . A liter bottle will be enough to completely replace the liquid. You need to fill the box with VAG G 052 512 A2 . You will need two liters of this liquid.

Some car owners are trying to save money and use cheaper transmission fluids. For example, FEBI 06161, SWAG 99906161 . They cost not much less than the original, but how their use will affect the service life of the gearbox has not been thoroughly studied. It’s up to you to take the risk or not, but car service technicians strongly recommend purchasing original transmission fluids.

What happens if you don't change the oil?

The role of transmission fluid is to clean parts and protect them from premature wear. The oil covers all surfaces with a thin film, preventing excessive friction and abrasion. This effect is achieved through the use of a liquid having a certain composition and viscosity.

Over time, foreign impurities appear in the transmission fluid, including tiny particles of metal that can scratch parts. In addition, the oil becomes more liquid, so it does not stay on the surface of the parts as well as fresh oil. The conclusion is obvious: all gearbox parts begin to deteriorate much faster, so the need for repairs may arise even during the first hundred thousand mileage.

What is DSG adaptation and when should it be carried out?

If, over time, jerks and jolts occur in the robotic box when moving, then it’s time to make an adaptation. The need for this procedure arises due to wear and deterioration in the efficiency of the clutch, which causes a decrease in the smoothness of gear shifting and the appearance of jerking. This ailment can be eliminated with the help of adaptation, which must be carried out after 15 thousand km or even earlier if the car is constantly used in a city with traffic jams. Ideally, you should not wait for shocks to appear and stick to an interval of 10-15 thousand km. Modern versions of the DSG are equipped with special travel sensors for the clutch fork and pulleys so that the electronics themselves adapt as the clutch wears out, regardless of the mileage of 10 or 15 thousand.

How to make an adaptation using the example of DSG DQ200

Adaptation is best done at a service center using a computer program, but thrifty owners of used cars often resort to a simplified method of DSG adaptation:

1. Drive 10-15 km to warm up the engine and gearbox
2. Turn off the engine and turn the key to activate the dashboard (in some cars, adaptation can be carried out with the ignition off)
3. Lower the door window and press the gas until the kick-down is activated so that an audible click appears in the transmission housing
4. Hold the accelerator for 40 seconds
5. Release the pedal and remove the ignition key
6. Reconnect the chain, start the engine and start driving.

How to drain old oil

Draining transmission fluid is easy. To do this, you will need a pit or a lift, containers for mining and hexagons for 6 and 10. After removing the protection, the lower part of the box and the drain plugs of the control unit and the box itself become visible.

You need to unscrew the plugs one by one and carefully drain all the liquid into pre-prepared containers. It is advisable to replace the plugs with new ones. Their tightening torque is 30 Nm. At this point, the oil drainage is complete, the protection can be returned to its place and proceed to the next stage.

DSG 6 device

DSG 6 (model DQ250) was developed in 2003. At the factory, the box is labeled as VW02 E, a distinctive feature of this box from the 7-speed “older friend”, released three years later, is the so-called “wet clutch”. This means that the gearbox disc packs are constantly immersed in an oil bath and operate under conditions of constant lubrication and cooling. This significantly increases the resource of both the discs themselves and the box as a whole.

Schematic structure of the box:

Main building blocks:

• double clutch box;
• crankcase;
• differential box;
• two rows of gears;
• control unit of the Mechatronic box;
• main gear.

The double clutch transmits torque to the gearbox's rows of gears. The drive disk of the box is connected to the friction clutches and the flywheel by a special hub, which also combines the gears.

The first row of gearboxes operates with odd gears and reverse gear. The second, accordingly, serves the remaining stages of the transmission.

The ECU is located in the box body, in the crankcase.

An equally important element is the electro-hydraulic unit, which carries out all the physical operations of changing gear ratios in the box. Its main components:

• control and solenoid valves of the box;
• multiplexer generating a control signal;
• box distribution spools.

When the driver moves the gearbox selector to one of the positions, the gearbox distributors are activated. Gears are changed using solenoid valves, and the clutch clutches are adjusted by pressure valves. Therefore, these valves can be called the “heart” of the box, and “Mechatronic” - its “brain”. The DQ250 box multiplexer controls the hydraulic cylinders. In DSG 6 there are 8 of these, but a maximum of 4 box valves are activated at the same time. When the multiplexer uses one mode or another, different cylinders are activated, depending on the gear selected on the gearbox.

Typical DSG gearbox selector:

Thus, the DSG 6 box operates on fairly simple shifting algorithms, changing gears cyclically. At one point, two rows of gears are engaged, but the second (currently inactive) is still working, just not being used. If the gearbox changes the gear ratio, the row is engaged without restarting, entering the activity phase. This allows you to reduce the gear shift time literally to a fraction of a second, making the car move smoothly and accurately, without the “thoughtfulness” typical of “slower” gearboxes. And this approach made it possible to give the box the name “preselective”, since the desired gear is always ready for work.

Filling with new oil

To fill the oil, you need to remove the cover and remove the starter, battery and its platform. This is quite difficult and time-consuming, which is why many auto mechanics prefer to fill the oil through the breather. This is much faster, although it requires some skill.

The mechatronics breather is located near the starter. To remove it, just place a 16mm wrench under it and carefully loosen the plastic plug. To add oil, you will need a hose with a diameter of 8 mm, a large-volume syringe or a funnel. The tube is connected to the hole, and a syringe with oil is attached to the other end. Transmission fluid is slowly poured into the mechatronics control unit. After 1 liter is filled, the hose is removed and the plug is put in place.

To gain access to the breather hole of the box itself, the gear selector must be moved to the “P” position. If this is not done, access will be limited by the lever. The gearbox breather plug can be easily removed by hand. The technology for filling oil is the same as for the control unit, but the gearbox will require 1.9 liters of transmission fluid. It is better to drain the oil into a separate container in order to accurately measure its volume and pour exactly the same amount. The breather plug is reinstalled and the car is ready to hit the road again.

Is it possible to change the oil yourself?

For a car enthusiast who has the appropriate skills, a garage with a pit and a minimum set of tools, changing the oil in the DSG-7 DQ200 independently is not difficult. It is better to buy transmission fluid from an authorized dealer. Random sellers may sell a fake that will negatively affect the performance of the transmission. If you want to save on car maintenance, enjoy the car repair procedure, want to be sure that everything is done efficiently and have hexagons, hoses, wrenches and containers for working on, you can easily carry out this procedure yourself.

For car owners without repair experience and tools, it is faster and cheaper to entrust their vehicle to an experienced technician. This will save time and guarantee the quality of gearbox maintenance. A good car service center will not only change the oil, but also inspect the car for faults. This will allow you to complete repair work on time and avoid troubles on the road. While the craftsmen are doing their work, you can solve your business issues or have a cup of coffee.

DSG boxes, after modernization and modification by the manufacturer, have become convenient and reliable, which cannot be said about the first versions of the robotic transmission. Compliance with the rules of their use, timely maintenance and the use of original technical fluids will allow you to easily travel much more than 100 thousand declared by the manufacturer.

How to extend the life of DSG-7

Knowing about the shortcomings of DSG, many caring car enthusiasts are wondering how to increase the service life of a robotic gearbox so that it pleases its owner with fast and clear shifts for as long as possible. In this case, you can do the following: simply reduce the oil change interval to 40 or 30 thousand km, so that it does not have time to deteriorate under any circumstances. This is especially true for harsh conditions of use, when you have to frequently change gears in city traffic jams.

Signs of deteriorating DSG performance due to bad oil

• extraneous sounds
• unclear gear engagement
• metallic clang
• kicks, jerks and vibrations
• lack of traction during acceleration

Signs of deterioration in oil quality in the DSG box

If the above symptoms are detected, it is necessary to check the condition of the transmission fluid.

1. Remove the engine protection, wipe the gearbox in the area of ​​the drain plugs
2. Unscrew the drain plug and drain the waste fluid
3. Assess the condition of the oil: - amber-yellow color does not give cause for concern - light or dark brown color indicates the presence of wear products and deterioration in oil quality

What negatively affects the reliability of DSG-7 and the shelf life of the oil

• constant movement around the city with traffic lights
• sudden throttle changes and frequent shifts
• using the wrong oil
• frequent slipping
• overheating of the box due to high load
• transportation of heavy loads and semi-trailers
• unqualified maintenance with deep intervention in the DSG design

Do-it-yourself oil change in DSG7

Having decided to change the oil yourself, the car owner must find a suitable place. If he does not have a garage with a service pit, you can ask friends or acquaintances to provide their premises for the work.

An even better option would be to have access to a lift. Currently, there are car repair shops that rent out their premises and equipment for short-term use to carry out car repairs.

In any case, you will need conditions that allow you to work comfortably and freely under the machine, so a regular overpass will do. If this issue is resolved, you can change the oil without any problems.

Car models where you can find the DSG7 gearbox

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. are). If on a conventional manual gearbox the clutch is clamped by design springs installed during manufacture, and when you press the clutch pedal, the clutch “releases”, thus no torque is transmitted, then in DSG7 the opposite happens, until the mechatronics gives the signal “released” to the clutches, they rotate freely , the mechatronics gives a signal, and the piston acts on the fork and the fork clamps the disk, and if there are no pressure leaks in the mechatronics, then the disk is clamped with the necessary force.

Diagnostic instruments contain the temperature value of the first and second friction disc; the temperature is calculated, i.e. how the clutch was slipping, how long, what torque was on the engine or what pressure was in the mechatronics, based on these readings the clutch temperature is calculated - this is the unmeasured temperature - this is the calculated temperature. If the calculated temperature begins to rise, it means that the clutch begins to slip excessively and the DSG7 gearbox will need to be repaired in the future.

Ford, Mercedes, Fiat have developed their DSG gearboxes with “dry” clutches. Ford abandoned hydraulics, installing electric motors, which are controlled by an electronic unit combined with electric motors, mounted on the box. Adaptation of the DSG7 Ford after replacing the electronic unit or double clutch is carried out automatically, unlike VW where it is necessary to carry out the adaptation procedure using 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 assembled, with adjusted disc clearances.

Basic box malfunctions

Subject to proper operating rules, the DSG 6 gearbox is quite reliable, has a long mileage and fine-tuning capabilities. But the design features also caused some problems with the box.

Friction clutch wear

Most often, the “disease” is manifested by jerking of the gearbox when engaging even-numbered gears or when reverse gear disappears. At the same time, the box goes into emergency mode, prohibiting gear changes, and information about errors enters the automatic transmission unit.

In this case, there is only one repair method - either replacing the entire clutch or individual friction discs (if the car's mileage is up to 150 thousand km). If the entire clutch was replaced on a DSG 6, the box must be adjusted using a proprietary diagnostic device; it is also advisable to adapt the DSG 6 clutch while in motion. Adaptation is also required when replacing disks.

Wear of control solenoids in the mechatronics unit

Another typical problem with these boxes, which manifests itself as “kicks” of the automatic transmission. In this case, the DSG gearbox does not go into emergency mode, and there are no errors in the memory either. The problem can be resolved by replacing the mechatronics or broken solenoids.

Classic problems with DSG7

The occurrence of defects in the operation of DSG7 is often associated with incorrect operation of the mechatronics

• There is no forward or reverse gear shifting,
• Jerks when changing gears.

After diagnostics, repair of the DSG7 mechatronics or its reprogramming is required. The reasons may be pressure leaks in the internal cavities, or incorrect operation of the gear shift software. Which leads to clutch slipping. Reprogramming the DSG7 is also required to update the software and optimize the operation of the box.

It is possible for the mechatronics unit to overheat in vehicle driving modes (providing a creeping mode) and, as a result, clutch discs to slip, subsequently repairing the DSG7, which is an operational defect in the operation of the DSG7. The manufacturer has recommended actions for DSG7 owners to force the transmission to switch from mode “D” to mode “N” when the car is in a traffic jam and stopped for more than 1 minute. VW developers did not count on the Russian specific operating conditions of the DSG7 (long hours of regular driving in traffic jams).

Also, 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 the exposed parts of the DSG7 from contamination. Failure of “dry” discs is possible for various reasons: Oil getting into the clutch (for example, due to a leak in the engine crankshaft oil seal), water, clogging of the clutch with dirt, etc. is a problem with a DSG7 gearbox with dry clutches.

The mechanical part of the DSG7 with high mileage is characterized by breakdowns of conventional manual 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 During the production of DSG7, modifications were made to individual components, improvements were made, installation dimensions for clutches were changed, and the release bearing drive lever was changed.

Owners of cars with DSG7 are faced with problems with the automatic transmission

• jolts when shifting forward or backward,
• shocks when switching,
• automatic transmission vibration,
• slipping on shifts,
• the car turns on emergency mode.

The average operational mileage of a car with DSG7 is 90-150 thousand km. Repair and replacement of the clutch is carried out using special tools. Repairing the DSG7 requires strict adherence to the assembly and adjustment technology in accordance with the manufacturer's requirements.

Changing the oil in the DSG7 gearbox can only be done in the gearbox. Replacement can be done after an average of 40 thousand mileage or as needed, because The manufacturer fills in oil for the entire service life.

Released software updates are an advantage of the DSG7. At the first signs of improper operation of the DSG7, you should start with diagnostics and, if necessary, “reflash” the mechatronics if they were produced by the manufacturer for your car, but we do not recommend “reflashing” a normally operating DSG7.

Diagnostics and consultations on the DSG7 box

ATG service engineers provide technical support in the form of consultations on technical issues related to the repair and operation of the 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 using specialized test devices. Deciphering and analyzing the received gearbox operation codes allows you to find the cause of incorrect automatic transmission operation and prevents DSG7 breakdown by timely detection of defects. One of the points of DSG7 diagnostics is to monitor the clutch temperature in operating modes. Clutch wear can be viewed programmatically.

Checking for leaks and changing the oil can be done at the ATG service center and is a necessary procedure aimed at maintaining the automatic transmission in working technical condition, in order to increase its trouble-free operation.

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

Question 001: Q: What is DSG? What types of DSG are there? What is the difference? What cars are they installed on? A: DSG (from German DirektSchaltGetriebe or English Direct Shift Gearbox) is a family of preselective robotic transmissions with dual clutches installed on VAG cars (Audi, Volkswagen, Skoda, Seat).

Looking at the table, we can draw some simple conclusions: 1. DSG with “dry” clutches, as a rule, are installed on less powerful engines, because
are able to “digest” a smaller moment. 2. If you have all-wheel drive, then you have “wet” clutches. 3. If you have a DSG and a longitudinal engine, then you have an Audi :-) 4. Apparently, the age of the legendary Audi Quattro all-wheel drive with the famous Torsen differential is coming to an end. Question 002:Q: How can I find out which gearbox is installed on my car? A: Option 1: Connect to the car with a diagnostic tool, go to block 02 - Transmission electronics and read the identification data. The first three characters of the box and mechatronics identifiers identify your box. For example: 0AM 300049H - seven-speed DSG with dry clutches type 0AM. Or 02E 300051R - six-speed DSG with wet clutches like 02E, etc. Option 2: Look by the vehicle's VIN code in the ETKA electronic spare parts catalog. Option 3: Send the vehicle's VIN code to our address, we will check and send you an answer. Question 003: Q: How does S-tronic for Audi differ from DSG for Volkswagen/Skoda/Seat? A: Nothing. With the exception of boxes 0B5, 0CK/0CL and 0СJ which are installed only on audio. Question 004: Q: What kind of oil is poured into the DSG? A: For convenience, we have formulated the answer in the form of a table:

Question 005:Q: What is mechatronics?
A: Mechatronik (mechatronik, mechatron, valve body, brain) - electronic-hydraulic control unit for the gearbox. Perhaps the most important, but at the same time the most unreliable unit in the entire transmission. Question 006: Q: What is the difference between mechatronics? A: Each type of DSG has its own type of mechatronics. Mechatronics from different types of DSG are not interchangeable. Moreover, for some types of DSG there are several generations of mechatronics, which also differ from each other. And for each type and generation of mechatronics, there are many versions of software designed for different engines and different gear ratios in the gearbox. In some cases, mechatronics of the same type can be reprogrammed (reflashed) for installation on different vehicles. You can read more about the firmware. Question 007:Q: Which DSG is better/more reliable? A: There is no clear answer to this question. Each type of DSG has its own advantages and disadvantages. And the “life” of any DSG largely depends on its operating conditions, such as: - Ambient temperature. All DSGs do not like overheating, especially for DSGs with “dry” clutches, in which the mechatronics have a separate oil circuit and there is no cooling; — Driving mode. Those who spend several hours every day in traffic jams have a greater chance of coming to replace mechatronics than those who mainly drive long distances on the highway; — Driving style. For those who like to “give the corner” and “light up at traffic lights”, the likelihood of having to replace the clutch and differential is much higher than for those who prefer a quiet ride. Question 008:Q: I have DSG7 0AM. Do I need to switch the selector to neutral when standing at a traffic light or in a traffic jam? A: No need. Unlike conventional manual gearboxes, the DSG7 0AM has a normally open clutch. And it closes only when the mechatronics begins to extend the clutch release rods. When you (or autohold) press the brake and hold the car in place, the mechatronics clutch rods are retracted and the clutches are open. Accordingly, no load is transferred to the gearbox or clutch. It doesn’t matter what position the selector knob is in. Question 009:Q: Over time, jerks appeared when changing gears. Previously, the car drove normally, the shifts were smooth, but recently there have been jerks and bumps when changing gears. Can this be fixed by reprogramming the transmission ECU (software update)? A: No you can't. The software cannot “deteriorate” over time and cause the CP to malfunction. If the car previously drove correctly, and then stopped, then the problem lies in the hardware, and not in the software. Reprogramming the mechatronics can only help if the mechatronics were changed and a unit with incorrect software was installed. You can read more about reprogramming. Question 010:Q: How to find out the software version in mechatronics? Question 011:Q: The DSG7 gear shift knob is locked in position P, how to unlock it in order to shift the gearbox to neutral? A: Brief instructions for unlocking the DSG7 0AM selector.

Question 012:Q: Will changing the oil in the DSG7 0AM(0CW) mechatronics help eliminate “kicks” during gear shifts? A: No, it won't help. Such malfunctions can be eliminated by repairing the hydraulic part of the mechatronics. In the initial stages, adaptation (basic installation) can help, but as an exception rather than a rule.

Question 014:Q: After replacing the mechatronics DSG7 0AM, the event recorder displays errors “06247 P1867 - Drive data bus, no messages from the steering column electronics - J527” and “06227 P1853 Drive data bus, unreliable message from the ABS control unit.” How to remove them? A: It is necessary to reset information about installed components (steering column switches, electric parking brake, etc.). To do this, you need to make a basic installation on channel 69. After completing the basic installation, the errors will go from the “constant” state to the “sporadic” state and they can be deleted.

When using VCDS software (VAG-COM, VASYA-Diagnostic, etc.): “02-Gearbox Electronics” -> “Basic. parameters - 04" -> In the "Group" field enter the value 69 -> Click "Read".

When using VAS-PC software: “Self-diagnosis” -> “02-Gearbox electronics” -> “006-Basic installation” -> In the “Group” field, enter the value 69 -> Press “Q”.

When using ODIS software: “Self-diagnosis” -> “02-Gearbox electronics” -> “Basic installation” -> Enter the value 69 -> Click “Channel selection”.

After the basic installation, you should clear the event recorder.

Question 015:Q: Structurally, DSG7 0AM and DSG7 0CW are almost identical transmissions (DQ200 family), is there any difference between the mechatronics installed on them? A: The main difference is the physical and software changes to the electronic control board. In particular, 0CW boards are tied to the vehicle immobilizer system. You can read more about the differences in mechatronics 0AM and 0CW.

DSG gearboxes began to be actively used on VAG group cars several years ago. Today, there are a significant number of cars on the secondary market that have this type of transmission.

The tradition is that buyers of used cars in Russia prefer to replace service fluids immediately after purchasing the vehicle. This is done to ensure that high-quality lubricants that meet the manufacturer’s requirements will be filled inside.

One of the first units to be serviced is the gearbox. If everything has long been known about the features of servicing automatic transmissions of the torque converter type, then in the case of cars with DSG gearboxes that have recently appeared on the secondary market, the information is fragmentary and contradictory.

Replacing fluid in the control unit

According to statistics, mechatronics is the most vulnerable element of the DSG. Many users are interested in the need to change the lubricant in it too. Unfortunately, this element is located separately inside the unit, so there is no possibility of regular maintenance without removing the gearbox. For this reason, replacement occurs only during its repair.

How not to kill the checkpoint?

Despite the fact that gearboxes of this type have become a step forward, their independent basic maintenance is now easier than that of conventional automatic transmissions. Changing the lubricant in a dry DSG can be done by an owner with ordinary skills.
