Checking and correcting ATF level Special tools and workshop equipment required

t  Used oil collection and extraction unit -V.A.G 1782-

t  ATF filling unit -V.A.G 1924-

t  Vehicle diagnostic, testing and information system -VAS 5051B- t  Safety goggles Procedure l  Gearbox must not be in emergency running (backup) mode. l  Drive vehicle onto lifting platform or inspection pit to make sure it is placed absolutely horizontal. l  Selector lever at position “P”. l  Exhaust hose(s) of an exhaust gas extractor (switched on) must be connected. l  Engine idling. l  The air-conditioner and heating system must be switched off.

l  Vehicle diagnostic, testing and information system -VAS 5051B- connected up; Vehicle self-diagnosis and vehicle system 02 - Gearbox electronics selected. l  The ATF temperature at the beginning of the test must not be higher than 35 °C. If necessary, first allow the gearbox to cool down.   Note 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 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. t  The ATF temperature is taken from the reading on the vehicle diagnostic, testing and information system -VAS 5051B-.

ATF temperature reading Display on -VAS 5051B-: –  From menu -1-, select function “Measured values” and advance by pressing → button.

Display on -VAS 5051B-: –  Using keypad -1- press buttons 5 for “Display group 005” and confirm entry by pressing Q button.

Display on -VAS 5051B-: –  Read off ATF temperature in display zone -1-. Checking and correcting ATF level   Note t  The ATF level is checked at the ATF inspection hole. 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 ATF filling unit -V.A.G 1924- with the ATF for the automatic gearbox 01M. l  ATF specifications → Electronic parts catalogue.   WARNING The ATF filling unit must be clean and the ATF must not be mixed with other types of ATF!

–  Secure reservoir for ATF filling unit -V.A.G 1924- as high as possible on vehicle. –  Place used oil collection and extraction unit -V.A.G 1782- below gearbox.   WARNING Wear safety goggles.

–  When ATF reaches temperature of 35 °C, unscrew ATF inspection plug -A-.

–  Cut open seal -arrow- for plug and renew.   Note

When the plug is opened, a small amount of ATF will always run out of the overflow pipe -arrow 2-. –  Check whether overflow pipe is screwed in as far as it will go (2 Nm). If ATF continues to come out through ATF inspection opening via overflow pipe before ATF has reached a temperature of 40 °C, the ATF level is OK.   Note t  The ATF inspection plug must be screwed in again at the latest when the ATF reaches a temperature of 45 °C (countries with hot climates: 50 °C). t  If ATF temperature exceeds 45 °C too much fluid will escape as it expands when heated. In this case the quantity of fluid in the gearbox is NOT sufficient! –  Fit new seal on plug -arrow 1- and tighten. l  Tightening torque: 15 Nm The ATF check is now completed. –  Exit from function “Measured values” by pressing ← button. –  Press “End output”. –  Switch off ignition and unplug diagnostic connector. If no ATF emerges from ATF inspection hole when ATF has reached 40 °C, fill up with ATF → Anchor.

Filling up ATF   Note Engine keeps running at idle speed.

–  Remove centre noise insulation (loosen fasteners -arrows-).

–  Remove left noise insulation -arrows-.

–  Prise off cap -arrow- securing sealing plug.   Note t  The cap -arrow- securing the sealing plug is supplied in two versions. t  The cap with snap-lock is damaged upon removal and must be renewed. t  The cap with a spring retainer can be used again. –  Detach sealing plug from filler pipe and attach pipe of ATF filling unit -V.A.G 1924- to filler pipe.

–  Fill with ATF using ATF filling unit -V.A.G 1924- until ATF comes out of inspection hole -arrow-.   Note t  The ATF inspection plug must be screwed in again at the latest when the ATF reaches a temperature of 45 °C (countries with hot climates: 50 °C). t  If ATF temperature exceeds 45 °C too much fluid will escape as it expands when heated. In this case the quantity of fluid in the gearbox is NOT sufficient! t  If necessary, switch off engine and allow gearbox to cool down.

–  Cut open seal -arrow- for plug and renew.

–  Fit new seal on plug -arrow 1- and tighten. l  Tightening torque: 15 Nm –  Attach sealing plug to filler pipe and secure with a new cap -arrow 2-: t  Renew cap with snap-lock and press onto sealing plug. t  Push cap with spring retainer onto sealing plug until it engages. –  Exit from function “Measured values” by pressing ← button. –  Press “End output”. –  Switch off ignition and unplug diagnostic connector. –  Install noise insulation → Rep.
