Checking and topping up ATF level in planetary gearbox Test conditions l  Gearbox must not be in emergency running (backup) mode. l  Vehicle must be absolutely horizontal (drive it onto a four-pillar lifting platform or over an inspection pit). l  Exhaust hose(s) of an exhaust gas extractor (switched on) must be connected. l  Selector lever in position “P”, engine idling. l  Air conditioner and heating system switched off. l  Vehicle diagnostic, testing and information system -VAS 5051B- connected up; “Vehicle self-diagnosis”, vehicle system “02 - Gearbox electronics”, “Measured values, display group 4” selected. l  The ATF temperature at the beginning of the test must not be higher than 30°C. If necessary, first allow the gearbox to cool down.

ATF temperature reading Display on -VAS 5051B-: –  Reading for ATF temperature is shown in display zone -1-. Checking and correcting ATF level   Note t  The ATF level is checked at the ATF inspection plug. t  The ATF level is correct if a small amount of fluid comes out at the ATF inspection plug 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). –  Fill container of ATF filling unit -V.A.G 1924- with ATF for automatic gearbox 01V, ATF specification → Chapter.   Caution The ATF filling unit must be clean and the ATF must not be mixed with other types of ATF!

–  Secure container for ATF filling unit -V.A.G 1924- as high as possible on vehicle. –  Start engine and let it idle.

–  Detach noise insulation -arrows-.

–  Place used oil collection and extraction unit -V.A.G 1782- below gearbox.   WARNING Wear safety goggles. –  When the ATF temperature reaches 35°C, unscrew the ATF inspection plug -2- and drain off any surplus ATF.

–  Renew seal -arrow- for ATF inspection plug.

If ATF comes out of the inspection hole before the ATF has reached 40°C the ATF level -arrow- is OK.   Note The ATF inspection plug must be screwed in again at the latest when ATF reaches a temperature of 45°C (or 50°C in hot climates). If no ATF emerges from ATF inspection hole when ATF has reached 45°C, top up with ATF → . –  Fit new seal on ATF inspection plug and tighten to 80 Nm. The ATF check is now completed. –  Exit “Vehicle self-diagnosis”, switch off ignition and unplug diagnostic connector. Filling up ATF If no ATF emerges from ATF inspection hole when ATF has reached 40°C, top up with ATF:   Note The ATF inspection plug must be screwed in again at the latest when ATF temperature reaches 45°C (or 50°C in hot climates). If necessary, switch off engine, allow gearbox to cool down and repeat the test.

–  Guide filler nozzle of ATF filling unit -V.A.G 1924- in from below through an opening in the deflector cap -arrow-, taking care not to push the deflector cap upwards out of position. –  Fill with ATF using ATF filling unit -V.A.G 1924- until ATF comes out of inspection hole.   Note The ATF level must not be too low or too high, otherwise this would impair the function of the gearbox. –  Fit new seal on ATF inspection plug and tighten to 80 Nm. –  Exit “Vehicle self-diagnosis”, switch off ignition and unplug diagnostic connector.
