^ ATF level is correct if a little bit of fluid still escapes at the ATF check plug between 35° and 45° C 1) (dependant on the fluid level when warming up).
1) For warm countries 50° C
- Secure container of VAG 1924 ATF filler tool as high up on vehicle as possible.
- Raise vehicle.
- Place VAG 1306 drip tray under transmission.
WARNING:
Wear protective glasses.
Once an ATF temperature of 35° C is reached, remove ATF check plug -2- and drain excess ATF if necessary.
^ If ATF exits from the ATF filler plug hole before the ATF reaches 40° C, the ATF level is OK
Note:
ATF check plug must be closed again by 45° C 1) at the latest.
1) For warm countries 50° C
^ Add ATF if no ATF has escaped from the ATF check plug hole by 40° C.
