Application: The fluid should be replaced every 4 years or 60,000 km, whichever comes first.
1. Apply the handbrake, raise the front of the vehicle and install safety stands. Remove the lower engine cover.
Application: For accuracy, Audi mechanics use an electrode tester connected to the electronic control system of the automatic transmission, which determines the temperature of the fluid (it should be within 35...40°C). Therefore, it is recommended to entrust this operation to specialists of the dealer car service. The procedure described below involves the final check of the oil level in the automatic transmission with the help of specialists of the dealer car service.
2. Please note that the liquid is poured from under the car, so the car should be raised quite high.
3. Place a suitable container under the automatic transmission. Wipe the pan, unscrew the control plug and remove it together with the measuring tube (Fig. 29.3). Drain the oil into the container.
Fig. 29.3. Components of the automatic transmission oil pan (01N):
1. Control plug
2. Measuring tube
3. Sealing cap with plug
4. Sealing cap type B, must be replaced after removal
5. Sealing cap of early models
6. Late model sealing cap
4. Screw in the measuring tube and tighten it to the specified torque.
5. Remove the sealing cap from the filler tube installed on the side of the pan.
Application: the sealing caps of later models must be replaced after any removal - they are disposable.
6. Pour liquid into the tray until it starts to flow out of the measuring tube.
7. Switch to "P" mode, start the engine at idle speed and warm it up to operating temperature. If necessary, add fluid until it starts to flow out of the measuring tube.
8. Press the brake pedal, engage each automatic transmission mode in turn for three seconds, then move the selector lever to position "P".
9. At this stage, Audi mechanics connect a tester to ensure that the fluid temperature is within the range of 35...40°C.
Note: If you add liquid at a lower temperature, you can pour it out too much. If you finish drinking liquid at a higher temperature, you can underfill it.
10. Keeping the engine idling, allow excess fluid to drain through the measuring tube.
11. Stop the engine, screw in the check plug with a new seal and tighten it to the specified torque.
12. Install the new sealing cap onto the filler tube.
13. Lower the vehicle.
