The gear oil for the 7-speed dual-clutch transmission 0CW is filled on a permanent basis (oils are designed for life). For this reason, the oil level is not checked and there is no inspection plug on this transmission.
In the event of a transmission leakage, the cause must be determined and the problem rectified.
The correct oil level in the gearbox can only be achieved by draining the old oil and then filling the gearbox with new oil in the specified amount. See DSG 0CW filling volumes.
Draining transmission oil
- Raise the vehicle.
- Place a pallet under the gearbox.
- Unscrew the oil drain plug on the gearbox (arrow).
Drain the oil.
- Install the oil drain plug.
Filling with gear 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 insufficient filling impairs the correct operation of the transmission.
New oil is filled through the air outlet.
If the transmission is on a 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 air filter
- Remove the battery and battery tray
- Remove the cover from the air outlet.
Install the VAS 6262/4 adapter on 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 dimension -a-: 210 mm.
Dimension -a- is measured from the shaft (green area in the illustration) of the oil filling adapter VAS 6262A.
Note: Shake the oil bottle well before opening to mix any deposits on the bottom of the oil bottle. Use only gear oil for 7-speed dual-clutch gearbox DSG - 0CW to fill, see Electronic Genuine Parts Catalog.
Screw the oil bottle onto the VAS 6262 A adapter.
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 transmission after refueling.
- Wipe the area around the air outlet with a cloth.

The manufacturer himself claims that the DSG robot is highly reliable and is a profitable solution compared to traditional hydromechanical automatic transmissions or CVTs. One way or another, it is important to understand that this box needs regular and high-quality maintenance, taking into account a number of features of its design.
Such maintenance should be understood, first of all, to change the oil in the DSG, as well as the DSG. Next, we will talk about when the oil in the DSG needs to be changed, how the oil in the DSG box is changed, and what to look for during this procedure.

Changing gear oil in a DSG robot: when is it needed and why
So, at the heart of the specified gearbox is a manual transmission, as well as (by analogy with a manual transmission). In other words, unlike "classic" automatic machines or a variator, there is no torque converter.
At the same time, there are two clutch discs, due to which the gears change very quickly and smoothly. The result is a high level of comfort and fuel efficiency, as well as impressive acceleration dynamics, as there is virtually no interruption in the power flow during gear changes, etc.
It controls the operation of the gearbox and clutch, as well as (analog). In fact, the electronic unit sends signals to the actuators, after which, due to the redistribution of fluid (oil) flows in mechatronics, gears are switched on and other processes are controlled.
It is quite obvious that the presence of such a device as a mechatronic means increased requirements for the quality and condition of the transmission oil. In other words, a timely oil change in the DSG box is necessary.
Immediately, we note that, according to the regulations, an oil change in DSG-6, and also often in DSG-7, is required every 60 thousand km. However, if the car is operated in difficult conditions (towing a trailer, aggressive driving, maximum loads), it is necessary to change the transmission oil earlier (the interval is reduced by 20-30 or even 40%).
Please note, DSG-6 is and can go about 200-250 thousand km. without repair. At the same time, it is important to understand that the result of an untimely oil change in the box at the same time as a violation of the operating requirements for the gearbox is the vast majority of DSG failures encountered.
Also, after changing the oil, most owners note that after replacing, for example, in the DSG-6, shocks disappear when switching, the gearbox works smoothly, without jerking. Next, we will look at the process of changing the oil in the DSG-6 with our own hands.
How to select and change oil in DSG
So, in order to change the oil in the DSG, it is necessary to select in advance a special transmission fluid or oil in the DSG box, which is suitable for units of this type. To change the oil in a DSG box, for example, DQ-250, you will need 6 liters of gear oil.
Considering that such a gearbox with a "wet" clutch (clutch packs are immersed in an oil bath), more oil is needed in this case. As for the DSG-7 with the so-called "dry" clutch, such a box requires less transmission fluid.
We also note that in addition to the liquid, it is necessary to change the oil filter of the DSG box, as well as a special sealing ring of the drain plug. As a rule, when replacing, original oils and transmission fluids with VW TL52182 approvals are used. You can also select suitable third-party counterparts.
The main thing is to use high quality products as well. If we talk about the replacement itself, you can either use the services of specialized service stations, or perform all the manipulations yourself.
- First of all, in addition to the oil and the gearbox filter, you will need a garage with a viewing hole or lift, a set of tools, containers for draining mining, rags;
- Before starting the replacement, the box must be warmed up by driving a car for about 10 km;
- Next, the machine is placed on a pit or lifted on a lift, if available, the engine protection is removed;
- Then you will need to remove the air intake along with the air filter, battery with a casing and a pan;
- Next, the plastic cup is unscrewed, the filter is removed;
- Then you need to remove the breather cap (located closer to the headlamp from the filter);
- Now you can go down under the car and unscrew the drain plug, substitute the container where the mining will be drained;
- After unscrewing the plug, a hex key is inserted into the hole, with which a special insert is unscrewed. This allows the maximum amount of oil to be drained;
- After removing the insert, you need to wait until all the oil is drained into the container;
- At the same time, you need to soak the new filter of the DSG box with fresh oil. To do this, you can insert the filter into the cup case and spill it with oil;
- After the oil has completely drained from the gearbox, the insert can be tightened, but the drain plug does not need to be tightened. If you tighten it, the oil will be poured into the unit faster;
- To avoid oil leaks, place a container in the area of the drain hole.
- Now it remains to insert the funnel into the gearbox breather (from above under the hood) and fill in fresh oil. Pour in slowly and carefully, dosing portions.
We also add that oil can be filled in in other ways (for example, pumped with a syringe through the drain hole), but in practice, filling through the breather is the fastest and most efficient. Also, after about 4.5 liters of oil has been poured into the box, you need to tighten the gearbox oil filter cover, replace the breather cap, install the previously removed elements of the engine intake system, connect the terminals to the battery.
At the same time, you do not need to tighten or twist anything yet. At the same time, the old gearbox drain plug is installed (we do not install a new one yet, the O-rings do not change either). Next, the engine must be started by connecting in parallel to the ECU through.
The main task is to wait until the oil in the DSG warms up to 40-48 degrees. After such heating, the engine does not need to be turned off, while the old drain plug should be unscrewed. It is important that the oil drips a little from the hole as a result of vibrations from a running internal combustion engine.
Then you need to wait some time until the excess flows out, that is, the required amount remains in the gearbox (the plug-in plug installed in the drain hole will not allow more grease to flow out). Please note that if the oil does not immediately drip when unscrewing the plug, this indicates that it is not filled in enough and needs to be refilled.
After the oil stops dripping, this will indicate the correct oil level in the gearbox. In this case, you can tighten the already new plug with an O-ring, and also turn off the engine. Now you can start reassembling by tightening all previously removed and unscrewed elements. This completes the oil change.
What is the bottom line
As you can see, although the DSG gearbox is not a "classic" automatic and is more like a manual transmission, the oil change in the DSG should be done more often and regularly.
The reason is the presence of mechatronics and increased sensitivity to transmission fluid in the gearbox. The manufacturer's own regulations also indicate the need for replacement, that is, such a box cannot be considered officially maintenance-free.
It turns out that the owners of car models with DSG-6 should take into account that the service life of the transmission directly depends on the timely replacement of the oil and the gearbox filter in the transmission. You also need to follow certain operating rules (avoid abrupt starts, high loads, slippage, towing a trailer and other cars).
Finally, we note that changing the oil in the DSG-6 or DSG-7 box in some cases allows you to improve the quality of the gearbox itself, get rid of jerks when shifting, the car accelerates better, the transmission makes less noise during operation, vibrates less so much, etc. NS.

To change the oil in DSG 7, we only need a container for working out 5-6 liters, a standard set of tools, a filling syringe and a tube with a diameter of 7-8 mm. What is nice is that during the replacement we do not have to pump anything, squeeze out anything, the work is almost the same as with a conventional manual transmission, with the exception of a few nuances.
And yet, when replacing, we will not remove either the starter, or the battery, or the platform for the battery. The only thing that will need to be dismantled is the engine protection. But a child can handle it too. If everything is ready, we can start replacing:
- After removing the protection, thoroughly clean the Mechatronic unit from dirt.
- Turn off the drain plug with a 5 hexagon.
- We substitute a container (about a liter) under the Mechatronic unit.
- We drain all the liquid from the control unit.
- We twist the drain plug into place.
- Now we clean the drain plug already on the gearbox.
- Using a 10 hexagon, unscrew the cork, substituting a container of about two liters.
- Let's wait until all the oil drains from the checkpoint.
- We measure the amount of drained oil, since no control hole is provided.
- We tighten the gearbox oil drain plug.
- Now pour oil into the Mechatronic control unit.
- Remove the plastic breather on the control unit from under the hood. It is located near the starter.
- To do this, use a 16 key. Place the key under the breather and, like a lever, remove it from the hole.
- We put a hose with a diameter of 8 mm on the breather fitting, pour a liter of G004 000 M2 oil into the syringe and pump oil into the mechatronic with smooth piston movements.
- If no filling syringe is available, a 150 cc medical syringe or any other device can be used. We put the breather in place.
- Now fill in the oil in the gearbox. We will do this also through the breather hole. To make it easier to get to it, we transfer the gearbox control selector to the Parking mode.
- Remove the plastic breather by hand.
- We put the same 8-mm hose on the breather fitting, fill the syringe with exactly the same amount of oil as we drained and pump it into the gearbox. After that we put the breather in place.
Thus, you can quickly change the oil in the DSG7 gearbox and the Mechatronic control unit on the Skoda Octavia A7. Successful work to all and reliable gearboxes!
DSG gearboxes have been actively used in vehicles of the VAG group several years ago. Today, a significant number of cars with this type of transmission are presented on the secondary market.
The tradition is that buyers of used cars in Russia prefer to replace service fluids immediately after purchasing a vehicle. This is done to ensure that quality lubricants that meet the manufacturer's requirements are poured inside.
Among the first units to be serviced is the gearbox. If everything has been known for a long time about the features of servicing automatic transmissions of a torque converter type, then in the case of cars with DSG boxes that have recently appeared on the secondary market, the information is fragmentary and contradictory.
What is DSG?
First, it's worth understanding the features of this transmission. This abbreviation stands for Gearbox with two clutches in German. In fact, it is a mechanic, the control of which is of an automated nature.
This design allows for quick response of the shifting mechanism, due to the fact that one clutch disc operates at even speeds and the other at odd speeds. The transmission pre-performs operations prior to changing gears.
Such designs also appear on cars from other manufacturers. However, when talking about DSG, it should be understood that we are talking about transmissions, under different names installed on the products of Skoda, Seat, Audi and Volkswagen.
Experts say that gearboxes of this design will replace the usual torque converter transmissions, since they provide faster operation. Other advantages are fuel efficiency and less power loss when transmitting torque to the drive wheels, as well as the relative compactness of the unit.
How is DSG7 different?
Two main types of DSG transmissions are installed on VAG cars. Some of them have a wet grip, while others have a dry one. The latter are called DSG7. Their design does not imply a hydraulic clutch cooling system. For this reason, such a transmission does not tolerate work in conditions of traffic jams and congestions: the absence of an incoming air flow often leads to overheating and its failure.
A distinctive feature of this model is the limitation of the torque of the motors used. They are used in vehicles of the concern, whose maximum thrust is within 250 Nm.
How to quickly and easily renew the lubricant in the gearbox?
Do I need to change the oil in the DSG?
This question is not idle, since the manufacturer's policy and operating features of this transmission may lead to conflicting conclusions. On the one hand, the manufacturer claims that the gearbox is not serviceable, so the oil in it cannot be changed. On the other hand, there are severe climatic and road conditions in Russia, which significantly affect the condition of the lubricating fluid.
There is a third point: experienced owners of cars with DSG7 claim that the transmission rarely has a resource exceeding 100 thousand km, so the oil can be changed during repairs.
Given the fact that the buyer is unlikely to purchase a car with gearbox faults (this can be detected during a test drive, during which characteristic twitching will be observed), it makes sense to facilitate its work. The oil in the unit that has been subjected to stress will obviously be worse than new. Changing the fluid will extend the life of many of its elements.
At what intervals should the DSG7 oil be changed?
Given that the manufacturer considers this transmission to be maintenance-free, there is no official recommendation for mileage or the period after which a new lubricant will be required. In such a situation, it is better to turn to the experience and advice of owners of cars with DSG.
Looking for information on the forums of the owners of these cars, you can find different points of view. Someone says there is no need to replace it, since the design uses a dry-type clutch, others insist on updating the oil almost in parallel with the engine oil. However, most experienced users point out the need to service the checkpoint every 30 or 40 thousand kilometers.
What is the best way to change: on your own or at the bus station?
In the face of the need to save the family budget, this issue is becoming more and more relevant for motorists. Of course, not everyone has the appropriate basic skills, a garage or the ability to use a lift on their own. Therefore, the dilemma exists only in these cases.
There is no universal recipe and every car owner must make an independent decision. Each of the options has its own advantages and disadvantages, each of which can be crucial if you need to change the oil. Below are the main pros and cons.
Oil change at service station
The positive aspects of oil change in a car service include the speed of the procedure and the absence of the need to work independently. And the presence of a lift will allow you to inspect the car for other malfunctions in good lighting conditions.
However, there are a number of disadvantages as well. If we are talking about an authorized dealer's service center, then the cost of work will seriously hit the pocket of the owner of such a car. Similar problems are possible in unauthorized services: unscrupulous employees can tell a large number of stories about the “incredible technical complexity” of DSG and the laboriousness of the operations performed.
Self-oil change
This method is unlikely to be suitable for the fair sex who owns a car with DSG7, since during the work you will have to apply physical effort. However, for many men who have the opportunity to use the garage, such work will even be a pleasure.
The main advantage is that you will have to pay exclusively for a new lubricant. This will save a significant amount on service costs, because the replacement will be done by hand. Another advantage will be confidence in the quality of the work performed: the owner will know for sure that all removable elements are back in place.
A plus for self-service DSG in comparison with an automatic transmission is the absence of the need to use special equipment for pumping the contents of the transmission.
The disadvantages, first of all, include the need to carry out the replacement operation in dirty conditions. For this reason, you should choose clothes that you don't mind getting dirty.
These actions will be difficult for users who do not have basic knowledge of the device of car units. An inexperienced owner runs the risk of draining the oil from the engine.
DIY oil change in DSG7
Having decided on an independent oil change, 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 his premises for work.
An even better option would be to be able to use the lift. Currently, there are car services 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 an ordinary overpass will do. If this issue is resolved, it will be possible to change the oil without any problems.
Tools that will be needed during work
The nice thing is that during the fluid change, you will not need special tools produced by the manufacturer to service their equipment. You will need the following:
- A set of keys with different sizes and leading principles;
- Funnel for filling liquid;
- The container into which the oil will be drained;
- A syringe with a hose at the end to collect the remaining oil in the checkpoint (in case of work on a lift or overpass);
- Jack (in the case when the oil is changed in the garage);
- A key with an indicator of the applied effort (it is desirable, but not required);
- Internal hex key 10 for unscrewing the gearbox drain plug;
- 2 liters of oil;
- Rags for cleaning surfaces from grease;
- Gloves;
- Drain plug for replacement.
What kind of oil should you add?
Initially, a synthetic lubricant was poured into the DSG7 boxes. However, due to the identified shortcomings during its use, the manufacturer carried out a recall campaign. In the course of it, a replacement was made for a mineral liquid, since the synthetics corroded the gasket and got inside the gearbox control unit (mechatronics). This led to the destruction of the latter.
As a result, mineral oil of the same composition as in mechatronics was poured into all transmissions. Currently, the manufacturer recommends filling with a service fluid that meets the 052 529 A2 standard. The easiest way to get it is from a dealer, but you can also pick up analogues offered by oil companies.
How to prepare the car for work?
It is important to warm up the transmission well before starting a replacement. To do this, it is better to make a preliminary trip, during which the oil inside will warm up. In this state, the liquid becomes more fluid and it will be much easier and faster to drain from the shafts and gears located inside during draining.
If in summer it is possible to do without a long preheating procedure, then in winter it will be difficult to drain the grease from the gearbox of a car that has stood in the cold for even less than an hour. Warm-up can be accelerated by frequent starting and stopping, this mode loads the transmission of this type most strongly and quickly.
Draining old fluid
Replacement begins by draining the old grease. It will consist of the following steps:
At the time of unscrewing the plug, you should be careful, because the liquid may flow past the container. In this case, the old plug becomes unusable, which does not require holding it while the grease is draining off. The new one should be screwed up to a force of 30 Nm. In the absence of a key that measures this parameter, there is a danger of thread breaking, so do not tighten it all the way.
Filling with new grease
In order to get to the checkpoint, you will have to remove the interfering elements under the hood. Depending on the car model, this can be a battery, its platform, as well as an air filter housing. There should be enough space for further work.
You can fill in oil in 2 ways:
- Through a black plastic breather on the plastic cover of the gearbox locking mechanism;
By removing the indicated cover.
The first method requires more accuracy, while the second involves additional operations.
Pour 1.9 liters of fresh grease through the funnel. After that, you need to perform all the steps in reverse order.
Changing the fluid in the control unit
According to statistics, the mechatronic is the most vulnerable element of the DSG. Many users are interested in the need to change the lubricant and in it. Unfortunately, this element is separately located inside the unit, so there is no possibility of its regular maintenance without removing the gearbox. For this reason, replacement takes place only during its repair.
How not to kill the checkpoint?
Despite the fact that this type of checkpoint is a step forward, their independent basic maintenance is now easier than with conventional automatic gearboxes. The change of grease in a dry DSG will be handled by the owner with the usual skills.

My life is not only connected with cars, but also with repair and maintenance. But I also have a hobby like all men. My hobby is fishing.
I started a personal blog in which I share my experience. I try a lot of things, various methods and ways to increase the catch. If interested, you can read it. Nothing more, just my personal experience.
Attention, only TODAY!
SEAT Leon Copa Plus car. Bundle 1.8TSI + DSG7 + ABS + ESP + EBD.
Robotic transmission 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, then the plug code - N10037105. Both items are taken from the catalog by VIN-number.
We spied on how to change the oil from Alexander Willwillis from Drive2.ru. He has everything clearly told and shown. A couple of additions from us. If you have never removed the air filter housing, then check in advance how it is done. At 1.8 TSI, to remove it, you need to carefully pull up, because it sits tightly on two landing pins of the battery platform, and rubber dampers are located in the filter housing mounting holes. 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 DSG-7 was carried out at a mileage of 76,000 km. What made us do this? Doubts! Doubts are that in the constantly contacting parts of the gearbox, the technical fluid can work out the entire life of the car and maintain its operational characteristics. 2 years of warranty - yes, the gear oil is capable of working. So what is next? And if the car 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 period. Therefore, they made a replacement. The result is below.

Subjectively, we did not do the oil change procedure in vain. The box began to switch very gently, barely noticeable.
19.07.2016 After changing the oil in the gearbox, 4 months have passed and 6,000 km have been driven. During this time, no problems arose: there were no smudges, fogging due to the filling of 2 liters of oil, and there are no. The car was accelerated 1 time to 200 km. in hour.
Our conclusion: the oil in the mechanical part of the DSG-7 needs to be changed. How often? We believe that every 60 thousand km.
