How to change the oil in a DSG box. How to change the oil in a DSG box When to change the oil in a DSG 7 box

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 him. DirektSchaltGetriebe or English. Direct Shift Gearbox) - a family of preselective robotic transmissions with dual clutches installed on VAG cars (Audi, Volkswagen, Skoda, Seat).

DSG7 0CL (DL382-7Q)	"wet"	longitudinal	2.0 - 3.0	full	400Nm	Audi: A4 (8W - from 2016).
DSG7 0СJ	"wet"	longitudinal	2.0	full (Ulta Quattro, with electromechanical clutch)	400Nm	Audi: A4 (8W - from 2016).

Looking at the table, you can draw some simple conclusions:
1. DSG with dry clutches are usually 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 century 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 the diagnostic tool to the car, 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 type 02E, etc.
Option 2: Look by the vehicle’s VIN code in the ETKA electronic spare parts catalog.
Option 3: Send the car's VIN code to our address, we will check and send you a response.

Question 003:
Q: How is S-tronic for Audi different 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:

Type	Oil	Replacement interval (manufacturer's recommendation)
DSG7 0AM (DQ200)		for the entire service life
DSG6 02E (DQ250)	Refill volumes: up to 6.9l - full filling up to 5.5l - oil change Filter element: 02E 305 051 C	60 000
DSG7 0B5	Gearbox oil DSG G 052 529 up to 7.5l - full filling up to 6.7l - oil change Filter element: 0B5 325 330 A	60 000
DSG7 0BT/0BH (DQ500)	Gearbox oil DSG G 052 182 up to 7.6 - full charge up to 6.0l - oil change Filter element: 0BH 325 183 B	60 000
DSG7 0CW (DQ200)	In the box: Gearbox oil G 052 512 - 1.9l In mechatronics: Hydraulic oil G 004 000 - 1 l	for the entire service life
DSG7 0D9 (DQ250)	In the box: Gearbox oil DSG G 052 182 Refill volumes: up to 6.9l - full filling up to 5.5l - oil change Filter element: 02E 305 051 C In the transfer case: G 052 145 - 0.9l	60 000

Question 005:
Q:What is mechatronics?
A:Mechatronik (mechatronik, mechatron, valve body, brain) - electronic-hydraulic control unit of the gearbox. Perhaps the most important, but at the same time the most unreliable unit in the entire transmission.

Question 006:
Q:How are mechatronics different?
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 a traffic light”, 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, there have been jerks when shifting gears. Previously, the car drove normally, the shifts were smooth, but latelythere were jerks and knocks 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 can I unlock it in order to shift?box 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 shows errors “06247 P1867 - Drive data bus, no messages from the steering column electronics - J527” and “06227 P1853 Drive data bus, invalid 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 the softwareVAS-PC:
"Self-diagnosis" ->"02-Gearbox electronics" -> "006-Basic installation"-> In the "Group" field enter the value 69 -> Press "Q".

When using the softwareODIS:
"Self-diagnosis" ->"02-Electronics Gearbox" ->"Basic installation" ->Enter the value 69 -> Click "Select channel".

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.

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 whose warranty has expired, it is clear that there is no point in continuing to service the car from an official dealer. In today's article we will talk in detail about how to independently change the oil in the DSG-7 gearbox in a Volkswagen Passat CC (there is practically no difference between changing the restyled and derestyling version, at least the process itself is completely similar). We will also consider the issue of choosing which oil The official dealer recommends filling the oil and what oil is best suited as an analogue so that you can save a little.

Owners of a used Volkswagen Passat SS 1.8 with DSG-7 often have a question: do they need to change the oil in the box or not? Disputes arise due to the fact that the DSG-7 uses a dry clutch, which is why many people mistakenly think that there is no oil in the box and therefore there is nothing to change. Let us hasten to dispel this myth.

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

The second most popular question, which logically follows from the first, is how much oil is needed to change? Having studied a huge number of forums where owners share their experiences, we came to a figure of 2.1 liters. For comparison, an oil change in the DSG-6 is 6 liters, it’s easy to remember the amount equal to the number of gears.

What kind of oil should I use?

It is best to pour the gear oil G 052 512 A2 recommended by the manufacturer; it is sold in liter bottles at a price
from 900 to 1,300 rubles depending on the region. This product is suitable for manual and robotic transmissions (DSG-7 DQ 200) installed on Audi, Skoda, SEAT and Volkswagen.

As an alternative, some use:

• FEBI 21829 price from 500 rubles per 1 liter;
• SWAG 10921829 price from 500 rubles per 1 liter;
• VAG GCN052512Z2 price from 900 rubles per 1 liter.

Step-by-step instructions for changing the oil yourself

Before proceeding to the description of the actions, in addition to the oil, you will need a drain plug; its cost is 170 rubles. The tools you will need are a “10” hexagon, a syringe with a flexible hose and the actual container where the old oil will be drained. This process must take place on a warm transmission. so let's get started:

1. remove the plastic protection;
2. unscrew the gearbox plug;
3. drain the oil;
4. tighten the plug;
5. install plastic protection;
6. remove the cap from the breather;
7. insert the tube into the hole;
8. fill in the oil (Important! you need to fill in exactly as much oil as the old one has poured out, since the box is not equipped with a dipstick, you will have to do the calculations yourself);
9. put the breather cap in place.

That’s basically the whole process, which shouldn’t cause any particular difficulties or take a long time. By the way,

Modern cars have a complex structure. This applies not only to engines, but also to gearboxes. Previously, automakers used only two transmissions - manual and automatic. Today new checkpoints appeared. One of these is the DSG robotic gearbox. It is installed on cars of the Volkswagen - Audi concern and has a special device (with two clutches and a dual-mass flywheel).

You need to understand that changing the oil in a DSG has some differences from classic gearboxes. What technology is used to perform this operation? What kind of oil should I put in the DSG box? DSG and much more - later in the article.

Regulations

You must always follow the rules. Oil (be it motor or transmission) is always a consumable material and sooner or later becomes unusable. Over time, the liquid loses its color and lubricating properties.

This negatively affects the resource of the box. Therefore, in order to keep the car in good condition, you should change the oil in the DSG mechatronics on time. Experts recommend doing this procedure every sixty thousand kilometers. But if the car is used in extreme conditions (frequent traffic jams or severe frosts), this period should be reduced to forty thousand kilometers.

What to pour and how much?

Many people want to know what kind of oil should be poured into the DSG. The dealer recommends using the original VAG product G052182A2. However, its cost is more than a thousand rubles per liter. Therefore, many people prefer analogues.

Thus, Pentosin FFl-2 oil has proven itself well. This is a German-made transmission fluid that costs 300 rubles less than the original Vagovskaya. However, when changing the oil in the DSG, these two fluids should not be mixed. If the original oil was previously used in the box, in the future it is better to use it.

Now it's worth talking about volume. How much oil should be in the DSG box? The filling volume is seven liters. But if it is a DSG 7 with a dry clutch, the volume is smaller - 1.9 liters.

note

In addition to new oil, to replace you also need to purchase:

Only after this can the oil in the DSG be changed.

Get to work

So, first you need to drive the car into the inspection hole. Then you should turn off the engine, having previously set the gearbox selector to “parking” mode. After this, unscrew the drain plug of the box pan. To do this you will need an 8mm hex socket. Pre-prepare an empty container for old oil with a volume of about five liters. It is advisable that it be clean (you need to determine whether there are chips in the old fluid). After draining the old oil, tighten the plug and inspect the condition of the fluid. If metal particles are detected, increased wear of the box elements can be noted. Such a gearbox may be unstable.

After this you need to get to the oil filter. It is located higher. To get it, you will have to remove the battery and the platform under it.

If access is difficult, you can also remove the air filter housing with pipes. Then unscrew the cap two turns and allow the remaining oil to drain into the crankcase. Then unscrew the cap completely and replace the filter element.

What next?

After this, you need to fill in new fluid. Some people add it directly to the housing of the new filter, but this is long and difficult (a liter is filled within ten minutes). Therefore, it is better to find an adapter that screws in instead of the oil drain plug. You also need a 10 mm hose (it is important that it is transparent). The length of the hose is about two meters. Its second end is pulled onto the neck of a narrow funnel, which is attached above the engine compartment.

After this, start the engine. The box should be warmed up. To do this, switch the gearbox selector to different modes. The oil should heat up to a temperature of 45 degrees. If the liquid was poured at room temperature, the box should warm up in three to five minutes.

At the next stage, the knob is unscrewed and a bottle of oil is installed instead (usually the liquid is sold in liters, so take that one). Place this bottle on the floor so that it is below the transmission level. In this case, excess liquid will flow through the transparent tube. As soon as the stream decreases to drops, the adapter is unscrewed and the oil drain plug is screwed in. The seal on it is first changed.

Please note that you only need to tighten the plug after changing the oil in the DSG by hand. After this, with the engine running, you need to switch modes again with a delay of five seconds. Next, return the lever to the “parking” mode (the engine does not turn off). Unscrew the plug again. If the oil drains, you need to wait until the excess goes away. Then you can tighten the plug and begin full operation.

Nuances

The most difficult part of this procedure is determining the exact temperature of the transmission oil. Specialists have a special device for this, which is connected via a diagnostic connector. But when replacing it yourself, they can do it without it. The main thing is to remember that the optimal temperature for checking the oil level is from 35 to 45 degrees Celsius.

It is worth remembering that both excess and lack of oil are harmful to a robotic transmission. The level should be average.

How to change the oil on a “dry” DSG 7?

Sequence of work on a seven-speed gearbox:

1. The protection that covers the checkpoint is being removed.
2. The drain plug is unscrewed.
3. The old oil is drained.
4. The remaining oil is pumped out using a syringe or by jacking up the car in the area of ​​the left front wheel.
5. The drain plug is screwed in.
6. The protection is put in place.

The liquid is poured through a plastic breather (it is black and is located on the plastic cover of the DSG locking mechanism). You can remove the cover completely, but to do this you will also have to remove the battery or air filter housing. Next, 1.9 liters of new fluid is poured. After this, the replacement procedure can be considered complete.

If this operation is performed in winter, the transmission should be preheated. It's better to take a short trip. This will make the oil less viscous, and it will drain faster from the gears and shafts located inside the transmission. In summer, you can do without preheating. The liquid already has normal viscosity at +20 degrees Celsius.

Conclusion

So, now you know how to change the oil on a robotic gearbox. As you can see, this operation can be done with your own hands.

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!

Manual for vehicles with DSG type 0CW/0AM.

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

For the 7-speed dual clutch transmission, only use replacement gear oil and 0CW hydraulic oil, see Electronic Catalog of Original Parts.
Transmission oil level - arrow A-, as well as the hydraulic oil level in the mechatronics - arrow B- cannot be verified. 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 observed exactly - the gearbox will only be filled correctly if this has been done.
Overfilling as well as underfilling impairs the proper operation of the gearbox.

New oil is filled through the air vent.
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 cover from the air outlet.

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

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.

Set of plugs for VAS 6122 engine
Funnel

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.

Insert funnel

Shake the hydraulic oil bottle thoroughly before filling.
- Fill with the specified amount of hydraulic oil.
- Install a new oil filler plug.
Install mechatronics

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

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.

The first unit 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.

What is DSG?

First, it’s worth understanding the features of this transmission. This abbreviation stands for dual-clutch gearbox in German. In essence, it is mechanics, the control of which is automated.

This design allows for quick operation of the switching mechanism, due to the fact that one clutch disc operates at even speeds, and the other at odd speeds. The transmission performs the operations that precede the transition between gears in advance.

Such designs also appear on cars from other manufacturers. However, when talking about DSG, it should be understood that we are talking about transmissions installed under different names on Skoda, Seat, Audi and Volkswagen products.

Experts say that gearboxes of this design will displace conventional torque converter transmissions, as they provide faster operation. Other advantages include 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?

VAG cars are equipped with two main types of DSG transmissions. Some of them have a wet clutch, while others have a dry clutch. The latter are called DSG7. Their design does not require a hydraulic clutch cooling system. For this reason, such a transmission does not tolerate work in traffic jams and congestion: the lack of incoming air flow often leads to overheating and failure.

A distinctive feature of this model is the limitation of the torque of the motors used. They are equipped with the concern's cars, whose maximum thrust is within 250 Nm.

How to easily and quickly update the lubricant in a gearbox?

Do I need to change the oil in the DSG?

This question is not idle, since the manufacturer’s policies and the operating features of this transmission can lead to conflicting conclusions. On the one hand, the manufacturer claims that the gearbox is not subject to maintenance, so the oil in it cannot be replaced. On the other hand, there are difficult 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 service life exceeding 100 thousand km, so the oil can be changed during repairs.
Considering the fact that a buyer is unlikely to purchase a car with a faulty transmission (this can be identified during a test drive, during which characteristic twitching will be observed), it makes sense to make its work easier. The oil in a 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 interval should you change the DSG7 oil?

Given that the manufacturer considers this transmission to be maintenance-free, there are no official recommendations regarding the mileage or period after which new lubrication will be required. In such a situation, it is better to turn to the experience and advice of owners of cars with DSG.

By searching for information on the forums of the owners of these cars, you can find different points of view. Some say there is no need for replacement, since the design uses a dry clutch, others insist on updating the oil almost in parallel with the engine oil. However, most experienced users indicate the need to service the gearbox every 30 or 40 thousand kilometers.

What is the best way to change: on your own or at the bus station?

In the context of the need to save the family budget, this issue is becoming increasingly relevant for car enthusiasts. Of course, not everyone has the necessary basic skills, a garage, or the ability to use a lift themselves. Therefore, the dilemma exists only in these cases.

There is no universal recipe and each car owner must make an independent decision. Each of the options has its own advantages and disadvantages, each of which can be decisive if it is necessary to change the oil. Below are the main arguments for and against.

Oil change at service station

The positive aspects of changing the oil at 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 faults in good lighting conditions.

However, there are a number of disadvantages. If we are talking about a service center of an official dealer, 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 labor-intensive nature of the operations.

Do-it-yourself oil change

This method is unlikely to be suitable for the fair sex who own a car with DSG7, since physical effort will have to be used during the work. However, for many men who have the opportunity to use a garage, such work will even be a pleasure.

The main advantage is that you will have to pay exclusively for new lubricating fluid. This will save a significant amount on service costs, because the replacement will be done by yourself. Another advantage will be confidence in the quality of the work performed: the owner will know for sure that all the removed elements are back in place.

An advantage when servicing the DSG yourself compared to an automatic transmission is that there is no need to use special equipment to bleed 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 structure of vehicle components. An inexperienced owner risks draining the oil from the engine.

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.

Tools you will need for work

The nice thing is that when changing the fluid 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 driving principles;
• Funnel for pouring liquid;
• A container into which the oil will be drained;
• A syringe with a hose at the end to collect residual oil in the gearbox (in case of work on a lift or overpass);
• Jack (in case the oil is changed in the garage);
• A key with an indicator of the applied force (it is desirable, but not required);
• Internal hex key 10 for unscrewing the gearbox drain plug;
• 2 liters of oil;
• A rag for wiping surfaces of grease;
• Gloves;
• Replacement drain plug.

What kind of oil should I use?

Initially, DSG7 boxes were filled with synthetic lubricant. However, due to identified deficiencies in its use, the manufacturer carried out a recall campaign. During this, a replacement was made with a mineral fluid, since the synthetic 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 inside all transmissions. Currently, the manufacturer recommends filling in service fluid that meets standard 052 529 A2. The easiest way is to purchase it from a dealer, but you can also find analogues offered by oil companies.

How to prepare a car for work?

Before starting the replacement, it is important to warm up the transmission thoroughly. To do this, it is better to make a preliminary trip, during which the oil inside will become warm. In this state, the liquid becomes more fluid and will flow much more easily and quickly from the shafts and gears located inside during draining.

If in the summer you can do without a long preheating procedure, then in the winter it will be difficult to drain the lubricant from the gearbox of a car that has been standing in the cold for even less than an hour. Warming up can be accelerated by frequent starts and stops; this mode loads the transmission of this type most heavily and quickly.

Draining old fluid

Replacement begins with draining the old lubricant. It will consist of the following stages:

When unscrewing the cap, 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 lubricant drains. The new one should be tightened to a force of 30 Hm. If there is no key that measures this parameter, there is a danger of the thread breaking, so do not tighten it all the way.

Pouring new lubricant

In order to get to the gearbox, you will have to remove the interfering elements under the hood. Depending on the car model, this could be the battery, its platform, as well as the air filter housing. There should be enough space for further work.

You can add 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, and the second involves additional operations.

1.9 liters of fresh lubricant must be poured through the funnel. After this, you need to perform all the steps in reverse order.

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.
