Don't miss

• The ATF inspection and filler hole must be sealed again before the ATF temperature reaches 45 °C (or 50 °C in hot climates).
• The ATF inspection and filler hole must be sealed again before the ATF temperature reaches 45 °C (or 50 °C in hot climates). If necessary, switch off engine, allow gearbox to cool down and repeat test.
• The ATF level must not be too low or too high, otherwise this would impair the function of the gearbox.

📋 Procedure

1. Observe test conditions and notes (see the separate procedure).
2. Using the diagnostic tester in Guided Fault Finding mode, go to Function/Component Selection and select the following menu items:
3. Select the value for Gearbox oil temperature (ATF) from the menu.
4. Read off ATF temperature. [Note: The ATF level can be checked at the ATF inspection and filler hole. The ATF level is correct if a small amount of fluid comes out at the ATF inspection and filler hole when ATF temperature is between 35°C and 45°C, or 50°C in hot climates (the fluid level rises due to expansion as it warms up).Renew plug for ATF inspection and filler hole.]
5. ⚠ Risk of damage to gearboxOnly the ATF available as a replacement part may be used for the automatic gearbox 0BK. Other types of oil cause malfunctions and/or failure of the gearbox. For the correct type, refer to Electronic parts catalogue. The adapter for filling ATF oil must be clean and the ATF must not be mixed with other types of ATF! — Attach ATF container with adapter for oil filling VAS 6262 A as high as possible on vehicle; for ATF specification refer to Electronic parts catalogue.

6. ⚠ Risk of damage to gearboxThe engine must not be started if only a little or no ATF remains in gearbox after repair work or after excessive ATF leakage. In this case the gearbox must be filled with ATF before proceeding further (see the separate procedure). — Remove rear noise insulation (2)General body repairs, exterior 66.

7. Start engine with selector lever in position "“P”".
8. With brake pedal still depressed, select all gear positions ("“P”", "“R”", "“N”", "“D/S”") one after the other at idling speed, maintaining each position for at least 10 seconds.
9. Shift gearbox into "“P”".
10. Allow engine to continue running at idling speed.
11. Place used oil collection and extraction unit VAS 6622 below gearbox.
12. ⚠ Risk of eye injury. Wear safety goggles. — When an ATF temperature of 35 °C is reached, unscrew plug for ATF inspection and filler hole (arrow A) and drain off any surplus ATF. [Note: The ATF inspection and filler hole must be sealed again before the ATF temperature reaches 45 °C (or 50 °C in hot climates).]
13. Tighten new plug for ATF inspection and filler hole. The ATF level check is now completed. [Note: The ATF inspection and filler hole must be sealed again before the ATF temperature reaches 45 °C (or 50 °C in hot climates). If necessary, switch off engine, allow gearbox to cool down and repeat test.]
14. Insert adapter for filling ATF oil VAS 6262/5 into ATF inspection and filler hole (arrow).
15. Fill up with ATF via adapter until ATF comes out of inspection and filler hole. [Note: The ATF level must not be too low or too high, otherwise this would impair the function of the gearbox.]
16. Tighten new plug for ATF inspection and filler hole (arrow A). The ATF level check is now completed.
