Audi Workshop Service and Repair Manuals

Checking and correcting ATF level 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  Selector lever at position “P”. l  Parking brake button must be pulled up to apply the electronic parking brake. l  Exhaust hose(s) of an exhaust gas extractor (switched on) must be connected. l  Air conditioner and heating system switched off. l  Vehicle diagnostic, testing and information system -VAS 5051B- must be connected. l  The ATF temperature must not be higher than 30°C at the beginning of the test. If the temperature is higher, allow the gearbox to cool down before proceeding.   Note t  The ATF temperature is taken from the reading on the vehicle diagnostic, testing and information system -VAS 5051B-. t  The ATF level will vary according to the ATF temperature. t  If the ATF level is checked when the ATF temperature is too low, this will result in overfilling. t  If the ATF level is checked when the ATF temperature is too high, this will result in underfilling. t  Both overfilling and underfilling will impair the function of the gearbox. Procedure –  Using the vehicle diagnostic, testing and information system -VAS 5051B- in Guided Fault Finding mode, go to Function/Component Selection and select the following menu items: t  Drive system t  0B6 gearbox t  01 - Self-diagnosis-compatible systems t  02 - Gearbox electronics t  02 - Gearbox electronics, Functions t  02 - Read measured value block –  Select measured value for gear oil temperature from list on vehicle diagnostic, testing and information system -VAS 5051B-. –  Read off ATF temperature. 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).   Caution Risk of damage to the gearbox. t  Only the ATF available as a replacement part may be used for the automatic gearbox 0B6. t  Other types of oil cause malfunctions and/or failure of the gearbox. t  For the correct type, refer to → Electronic parts catalogue. t  The ATF filling unit must be clean and the ATF must not be mixed with other types of ATF!

–  Fill reservoir of ATF filling unit -V.A.G 1924- with ATF for automatic gearbox 0B6. For ATF specification refer to → Electronic parts catalogue. –  Secure reservoir for ATF filling unit -V.A.G 1924- as high as possible on vehicle.   Caution Risk of damage to the gearbox. t  The engine must not be started if only a little or no ATF remains in gearbox after repair work or after excessive ATF leakage. t  In this case the gearbox must be filled with ATF before proceeding further → Chapter.

–  Remove noise insulation (rear) → Rep. Gr.66. –  Start engine with selector lever in position “P”. –  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. –  Shift selector lever into position “N”. –  Increase engine speed to 2000 rpm for at least 60 seconds. –  Shift selector lever into position “P”. –  Allow engine to continue running at idling speed. –  Place used oil collection and extraction unit -V.A.G 1782- below gearbox.   WARNING Risk of eye injury. Wear safety goggles.

–  When an ATF temperature of 35 °C is reached, unscrew the ATF inspection plug -arrow B- and drain off any surplus ATF.   Note The ATF inspection plug is accessible via the opening in the tunnel cross member.

l  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 (countries with hot climates: 50°C).

–  Fit new seal -arrow- on ATF inspection plug and tighten to 9 Nm. The ATF level check is now completed. –  Install noise insulation → Rep. Gr.66. l  If no ATF emerges from ATF inspection hole when ATF has reached 40 °C: Filling up 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 -arrow- on ATF inspection plug and tighten to 9 Nm. The ATF level check is now completed.

–  Remove remaining ATF on tunnel cross member and clean tunnel cross member thoroughly.   Note t  There are several recesses in the top of the tunnel cross member in which ATF can collect. t  These must be cleaned thoroughly. t  -Arrows- can be disregarded. –  Install rear noise insulation → Rep. Gr.66.
