How to change the oil in a DSG box. How to change the oil in a DSG box Do they change the oil in a dsg 7 box

Modern cars have a complex structure. This applies not only to engines, but also boxes. Previously, automakers practiced only two transmissions - a mechanic and an automatic. Today there are new checkpoints. One of these is a robotic DSG box. 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 boxes. What technology is used for this operation? What kind of oil to pour into the DSG box? DSG and much more - further in the article.

Regulations

You always have to follow the rules. Oil (be it engine or transmission oil) is always consumable and sooner or later it will fail. Over time, the fluid 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 oil to fill in the DSG. The dealer recommends using the original VAG product G052182A2. However, its cost is more than a thousand rubles per liter. Therefore, many prefer analogues.

So, Pentosin FFl-2 oil has proven itself well. This is a German-made transmission fluid that costs 300 rubles cheaper 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, it is better to use it in the future.

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

note

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

Only then can the oil in the DSG be changed.

Get to work

So, first you need to drive the car into a viewing hole. Then you should turn off the engine, after setting the gearbox selector to the “parking” mode. After that, unscrew the drain plug of the box pan. You will need an 8mm hex socket for this. Prepare an empty container for old oil with a volume of about five liters. It is desirable that it be clean (you need to determine if there are chips in the old fluid). After draining the old oil, tighten the plug and inspect the condition of the liquid. In case of detection of metal particles, increased wear of the box elements can be stated. Such a checkpoint may be unstable.

After that you need to get to oil filter. He is above. To get it, you will have to dismantle the battery and the platform under it.

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

What next?

After that, you need to fill in new fluid. Some people add it directly to the new filter housing, but this is long and complicated (a liter is poured over ten minutes). Therefore, it is better to find an adapter that is screwed in instead of an 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 over the throat of a narrow funnel, which is attached above engine compartment.

After that, start the engine. Warm up the box. To do this, switch the gearbox selector to different modes. The oil should be heated to a temperature of 45 degrees. If room temperature liquid was poured, 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 it). Place this bottle on the floor so that it is below the level of the transmission. In this case, excess liquid will drain through the transparent tube. As soon as the jet decreases to drops, the adapter is unscrewed and the oil drain plug is screwed on. Previously, the seal is changed on it.

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

Nuances

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

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

How to change the oil to a "dry" DSG 7?

The sequence of work on the seven-speed box:

1. The protection is being removed, which covers the checkpoint.
2. The drain plug is loosened.
3. The old oil is drained.
4. The remaining oil is pumped out with a syringe or by jacking up the machine in the area of ​​the left front wheel.
5. The drain plug is screwed on.
6. The protection is in place.

Liquid is poured through a plastic breather (it is black and is located on the plastic cover of the DSG blocking mechanism). You can completely remove the cover, but this will also require dismantling the battery or air filter housing. Next, 1.9 liters of new fluid is poured. After that, the replacement procedure can be considered completed.

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

Conclusion

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

Box DSG gear type 0CW (DQ200) has two separate oil fills. One for gear oil and one for hydraulic oil. The gearbox oil level is 0CW 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 DSG - 0CW dual clutch transmission 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 a 7-speed dual clutch transmission, use only the spare transmission oil and hydraulic oil 0CW see e-catalogue original spare parts.
Gearbox 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 7-speed dual clutch transmission 0CW is permanently filled (oils are designed to last a lifetime). For this reason, the oil level is not checked and the check plug is not on this gearbox.

In the event of a transmission leak, 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 filling the gearbox with new oil in the specified quantity. See charge quantities DSG 0CW .

Draining gear oil
- Raise the car.
- 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 observed exactly - the gearbox will only be filled correctly if this has been done.
Overfilling as well as underfilling impairs the correct operation of the gearbox.

New oil is filled through the air outlet.
If the gearbox is on the vehicle, depending on the model and engine, the air filter or battery with battery tray must be removed when filling the gearbox with oil.

Remove air filter
- Remove the battery and battery tray
- Remove the cap from the air outlet.

Install adapter VAS 6262/4 on 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 the dimension -a-: 210 mm.
Dimension -a- is measured from the shaft (green area in the figure) of the VAS 6262A oil filling adapter.

Note: Shake the oil bottle before opening to mix any deposits at the bottom of the oil bottle. For filling, use only gear oil for 7-speed dual clutch transmission 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.

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

If hydraulic oil is lost from the mechatronics, correct level oil can only be set by changing the oil. During installation work the mechatronics must be hermetically sealed.
Insufficient hydraulic oil and overfilling affect the mechatronics and may cause malfunctions.

Condition:
Mechatronic must be removed

Question 004:
Q:What oil is poured into the DSG?
A:For convenience, we have formulated the answer in the form of a table:

Question 006:
Q:How are mechatronics different?
A:Each type of DSG has its own type of mechatronics. Mechatronics from different DSG types 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 cars. You can read more about the firmware.

Question 007:
Q:Which DSG is better/more reliable?
A:There is no single answer to this question. Each type of DSG has its own advantages and disadvantages. And the duration of the "life" of any DSG largely depends on the conditions of its operation, such as:
- Ambient temperature. All DSGs do not like overheating, especially 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 are more likely to come to replace the mechatronics than those who mainly drive long distances on the highway;
- Driving style. Those who like to "give a corner" and "light it up at a traffic light" are much more likely to get to replace the clutch and differential than 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 push the clutch release rods. When you (or auto-hold) hold the car in place by depressing the brake, the mechatronics clutch rods are retracted and the clutches are disengaged. Accordingly, no load is transferred to the gearbox or clutch. What position the selector lever is in is not important.

Question 009:
Q: Over time, jerks appeared when shifting gears. Previously, the car drove normally, the shifts were smooth, but recentlythere were jerks and bumps when shifting gears. Can this be fixed by reprogramming the box ECU (software update)?
A: No you can't. The software cannot "spoil" 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 you changed the mechatronics and installed the unit with the wrong software. You can read more about reprogramming.

Question 010:
Q:How to find out the software version in mechatronics?
Question 011:
Q: The DSG7 shift knob is locked in the P position, how do I unlock it in order to shiftbox in neutral?
A: Brief instructions for unlocking the DSG7 0AM selector.


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




Question 014:
Q: After replacing the DSG7 0AM mechatronics, the 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" hang in the event recorder. How to remove them?
A:It is necessary to reset information about the installed components (steering column switches, electric parking brake, etc.). To do this, you need to do the basic installation on channel 69. After the basic installation is done, the errors will go from the "permanent" state to the "sporadically" state and can be cleared.

When using VCDS software (VAG-COM, VASYA-Diagnost, etc.):
"02-KP 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 setting"-> In the "Group" field, enter the value 69 -> Press "Q".

When using the softwareODIS:
"Self-diagnosis" ->"02-KP Electronics" ->"Basic installation" ->Enter the value 69 -> Press "Channel Selection".

After completing the basic installation, clear the event recorder.


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

To change the oil in the 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 anything out, the work goes 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 pad under 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 the replacement:

1. After removing the protection, carefully clean the Mechatronic unit from dirt.
2. Unscrew the drain plug with a 5 hexagon.
   
   
3. We substitute a container (about a liter) under the Mechatronics block.
4. Drain all fluid from the control unit.
   
   
5. Screw the drain plug into place.
6. Now we clean the drain plug already on the gearbox.
   
   
7. We unscrew the cork with a 10 hexagon, substituting a container of about two liters.
   
   
8. Let's wait until all the oil drains from the gearbox.
   
   
9. We measure the amount of drained oil, since no control hole is provided.
10. Tighten the gearbox oil drain plug.
    
    
    
11. Now fill the oil into the Mechatronic control unit.
    
    
12. We remove the plastic breather on the control unit from under the hood. It is located near the starter.
13. To do this, use the key for 16. We substitute the key under the breather and, as a lever, take it out of the hole.
14. We put a hose with a diameter of 8 mm on the breather fitting, pour a liter of oil G004 000 M2 into the syringe and pump the oil into the mechatronics with smooth movements of the piston.
    
    
15. If there is no primer syringe, a 150 cc medical syringe or any other device can be used. We put the breather in place.
    
    
16. Now pour oil into the gearbox. This we will also do through the breather hole. To make it easier to get to it, we transfer the gearbox control selector to the Parking mode.
    
    
17. Remove the plastic breather by hand.
    
    
18. 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. Good luck to everyone and reliable gearboxes!

The manufacturer himself claims that the DSG robot is highly reliable and is a cost-effective 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 primarily as an oil change 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 as part of this procedure.

Changing gear oil in a DSG robot: when is it needed and why

So, at the heart of the specified checkpoint is mechanical box, and also (by analogy with the manual transmission). In other words, unlike the "classic" automatic or CVT, there is no torque converter.

At the same time, there are two clutch discs, due to which the gears switch very quickly and smoothly. The result is a high level of comfort and fuel efficiency, as well as impressive acceleration dynamics, since there is practically no interruption in the power flow during shifts, etc.

Controls the operation of the box and clutch, as well as (analogue). 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 gear oil. In other words, a timely oil change in the DSG box is necessary.

We note right away that according to the regulations, an oil change in the DSG-6, and also often in the DSG-7, is necessary every 60 thousand km. However, if the vehicle is used in severe conditions (trailer towing, aggressive driving, maximum loads), the transmission oil needs to be changed 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 is not timely replacement oil in the box, along with a violation of the operating requirements for the gearbox, is the vast majority of DSG breakdowns encountered.

Also, after an oil change, most owners note that after the replacement, for example, in the DSG-6, the shocks disappear when switching, the box works smoothly, without jerks. Next, we will consider the process of changing the oil in the DSG-6 with our own hands.

How to choose and change oil in DSG

So, in order to change the oil in the DSG, you must first select 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, 6 liters of gear oil will be required.

Considering that such a gearbox has 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, a smaller amount is required in such a box 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 for the drain plug. As a rule, when replacing original oils and transmission fluids with VW TL52182 approvals. You can also select suitable analogues from third-party manufacturers.

The main thing is to use products High Quality, as well as . 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 oil and a gearbox filter, you will need a garage with an inspection hole or a lift, a set of tools, containers for draining mining, rags;
• Before starting the replacement, the box must be warmed up by driving about 10 km;
• Next, the car is placed in a pit or lifted on a lift, if available, the engine protection is removed;
• Then you need to remove the air intake along with air filter, joint stock bank with a casing and the pallet;
• Next, the plastic cup is unscrewed, the filter is removed;
• After you need to remove the breather cap (located closer to the headlight from the filter);
• Now you can go down under the car and unscrew the drain plug, substitute a container where mining will merge;
• After unscrewing the plug, a hex key is inserted into the hole, with which a special insert is unscrewed. This allows you to drain the maximum amount of oil;
• After removing the insert, you need to wait until all the oil has drained into the container;
• In parallel, you need to saturate the new DSG box filter with fresh oil. To do this, you can insert the filter into the cup body and spill it with oil;
• After the oil has completely drained from the gearbox, the insert can be screwed in, but the drain plug does not need to be screwed in. If it is screwed in, the oil will be poured into the unit faster;
• To avoid oil leaks, a container should be placed in the area of ​​​​the drain hole.
• Now it remains to insert a funnel into the gearbox breather (from above under the hood) and fill in fresh oil. Pour should be 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), however, in practice, filling through a breather is the fastest and most efficient. Also, after about 4.5 liters of oil have been poured into the box, you need to tighten the gearbox oil filter cover, put the breather cap in place, install the previously removed elements of the engine intake system, and connect the terminals to the battery.

At the same time, it is not necessary to tighten and twist anything else. At the same time, the old gearbox drain plug is installed (we do not install a new one yet, the sealing rings do not change either). Next, the engine must be started by connecting to the computer in parallel 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 the vibrations of the running engine.

Then you need to wait some time until the excess flows out, that is, the right amount remains in the gearbox (the plug-insert installed in the drain hole will not allow more grease to leak out). Please note that if the oil does not immediately drip when the plug is unscrewed, this indicates that it is not filled enough and needs to be topped up.

After the oil stops dripping, this will indicate the correct oil level in the gearbox. In this case, you can screw in a new plug with a sealing ring, as well as turn off the engine. Now you can proceed to reassembly by tightening all previously removed and untwisted elements. This completes the oil change.

What is the result

As you can see, although the DSG box is not a “classic” automatic and is more like a manual transmission, the oil in the DSG should still be changed more often and performed regularly.

The reason is the presence of mechatronics and increased sensitivity to the 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 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 gearbox filter in the transmission. You also need to follow certain operating rules (avoid sudden starts, high loads, slippage, towing a trailer and other cars).

Finally, we note that changing the oil in a DSG-6 or DSG-7 box in some cases improves the quality of the gearbox itself, gets rid of jerks when switching, the car accelerates better, the transmission makes less noise during operation, does not vibrate so much, etc. P.
