What is the Audi transmission fluid change interval for DSG transmissions?
How often should Audi DSG transmission fluid be changed? The recommended service interval for changing the Audi transmission fluid on DSG transmissions is every 40,000 miles. This includes the DSG transmission fluid and filter. Those with an aggressive driving style, constant extreme heat, heavy city traffic, trailer pulling, or other severe driving conditions may want to replace the DSG transmission fluid sooner or more frequently. Changing your 6 speed Audi DSG transmission fluid is important and helps extend the life of your transmission.
A variety of Audi models came equipped with the direct shift gearbox (DSG) transmissions. The design yields better RPM control for more powerful and a more instantaneous shift. The DSG transmission features both manual and automatic modes of operation. For this reason, in this article Audi DSG transmission fluid is not strictly referred to as Audi "automatic" transmission fluid (aka Audi ATF).
What type of Audi transmission fluid does the DSG transmission use?
- The 02E and 0D9 6-Speed DSG transmissions use Audi VW TL 521 82 transmission fluid quality specification.
- Audi VW TL 521 82 transmission fluid is also known as OE part numbers G 052 182 A2 and G 052 182 A6.
What is the Audi transmission fluid fill capacity for the DSG transmission?
- The transmission fluid service fill for the DSG 6-Speed is 5.2 liters (5.49 US quarts).
- The transmission fluid dry fill capacity for the DSG 6-Speed is 7.2 liters (7.6 U.S. Quarts).

Audi DSG Transmission Fluid Filling Procedure:
How To Step 27
With the filling tool adapter VAS 6262 installed, slide the fill hose on as pictured.
How To Step 28
With the fill hose up in front of the Audi A3, S3, and TT transmission, connect the hose to the fluid bottles as described in the supplied tool and hose kit instructions. Connect the hose to the DSG fluid bottle as described in the supplied instructions.
How To Step 29
Allow around 2.5 liters of DSG fluid to flow by gravity into the transmission. As fluid is being fed into the transmission, with the vehicle elevated, and level off the ground, start the vehicle. With the brakes applied, shift/select through all the gears of the transmission while the engine is idling. Allow 5 seconds for each gear selection. While the engine is in park and idling, continue to gravity feed the DSG fluid into the transmission. This will allow several more liters to flow into the transmission. Allow all 5.2-6 liters to empty and flow into the DSG transmission, quickly remove the fill adapter and hose and install the drain plug and sealing washer snug. The Drain plug only needs to be tight enough to minimize a leak. We will be removing the drain plug again during a later step.
Blauparts’ DSG Transmission Fluid Fill Tool Alternative
If you would like a quick flow of DSG fluid into the transmission for the above step 29 process you can use pump tool number J91001. See our J91001 Instructional Document that shows how to adapt the pump to the Ravenol bottle spout tube. The hand pump base can be adapter directly to the Ravenol bottle tube that pulls out from the Ravenol bottle cap. As the fluid is pumped into the transmission, the bottle will collapse as the fluid is sucked from it. This may not be the prettiest way to pump fluid into the transmission, but it is an adequate and cost-effective way to fill the fluid, rather than having to buy the more expensive and .
How To Step 30
As the engine is at idle. Plug the Ross-Tech diagnostic software into the OBD2 port and begin to monitor the Audi A3, S3, and TT transmission fluid temperature.
Using the Ross-Tech:
- 1st Select Control Module
- 2nd 02-Auto Trans Control Module
- 3rd Measuring Blocks – 08
- 4th Group 019
Display group 019 in field 1 will allow for an accurate DSG fluid temperature reading.
How To Step 31
With the vehicle level, bring the transmission fluid temperature to warm between 35°C - 45C° (95°F –113°F). At this temperature range, you can remove the transmission drain plug and transmission fluid should begin to flow out from the fill port level insert. When this happens, the proper DSG fluid level has beeing achieved. The DSG fluid level is correct when the DSG fluid transitions from a consistent stream into its very first drip between the fluid temps of 35°C - 45C° (95°F –113°F).
Side Note: Do not allow the Audi A3, S3, and TT transmission temperature to exceed 45C° (113°F). Reinstall the 14mm hex bit drain plug before the transmission fluid temperature exceeds 45C° (113°F).
Side Note: If no fluid drips from the fill port between the temperatures of 35°C - 45C° (95°F – 113°F), proper level has not been achieved. Reinstall the 14mm hex bit drain plug, turn off the engine, and allow the transmission to cool to below 30°C (86°F). Repeat the DSG transmission fluid level process per the above recommended steps 27 - 33.
How To Step 32
Reinstall the 14mm allen drain plug with new sealing crush washer and torque to 22 ft lbs. 22 ft lbs allows for an adequate compression and sealing of the drain plug crush washer.
How To Step 33
Once the proper transmission fluid level has been attained, turn the engine off and exit the Ross-Tech diagnostic software and disconnect the OBD2 plug port.
How To Step 34
If you do not have a Ross-Tech diagnostic software available to you for reading the internal transmission fluid temperature you can use any diagnostic software that can access and read the internal transmission fluid temperature. The most accurate transmission fluid level and temperature reading is achieved using diagnostic software.
However, if you do not have diagnostic software, you may wish to use other options to read the transmission fluid temperature. One alternative is an infrared thermometer (See Image). Typically, an infrared thermometer reads within a 4-5 degree temperature difference when compared to diagnostic software which measure the true internal transmission fluid temperature. Thus, an infrared thermometer can be a reliable temperature source when performing the transmission fluid leveling sequence. If an infrared thermometer is used it is best to allow the fluid temperature and level reading to be more towards the low side of the temperature window of 35°C - 45C° (95°F–113°F). For example, a 34°C reading will be closer to a 38-39°C internal fluid temperature reading.
How To Step 35
Re-install the lower engine splash pan with T-25 torx.
How To Step 36
Remove the Audi A3, S3, and TT from the approved automotive lift or jack stands using factory lift points and procedures.
How To Step 37
Dispose of the old DSG fluid responsibly by taking it to a certified recycling collection center.
Its also good to note in your records the current mileage of when your DSG fluid change was done, as well as, when you'll need to change your fluid next. Keeping detailed service records is a must for proper vehicle maintenance and good vehicle resale value.
