Checking and correcting ATF level Special tools and workshop equipment required t  Vehicle diagnostic tester

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

t  ATF charging device for CVT gearboxes -VAS 5162- t  Safety goggles

Preparations:   Note t  The illustration on the reservoir of the ATF charging device for CVT gearboxes -VAS 5162- displays a warning in the top left corner to use ONLY the ATF specially formulated for CVT gearboxes. t  The illustration also shows the steps to follow when filling up; these are also described below.   Caution Risk of damage to 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 you need to fill the gearbox first with 5.5 … 7 litres of ATF.

l  Different versions have ATF inspection plugs -A- of different lengths. The ATF inspection plug must be renewed after checking the ATF level. Always select correct version according to gearbox code letters in → Electronic parts catalogue. To prevent damage to the gearbox, please check the new ATF inspection plug by comparing it with the old one. 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  Electromechanical parking brake applied. l  Exhaust hose(s) of an exhaust gas extractor (switched on) must be connected. l  The air-conditioner and heating system must be switched off. l  Vehicle diagnostic tester is connected. 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.   Note t  The ATF temperature is taken from the reading on the vehicle diagnostic tester. 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. t  The ATF temperature is taken from the reading on the vehicle diagnostic tester. Checking and correcting ATF level   Note The ATF filler and inspection plug must be renewed. –  Using the diagnostic tester in „Guided Fault Finding“ mode, go to Function/Component Selection and select the following menu items: t  Drive system t  0AW gearbox t  01 - Self-diagnosis-compatible systems t  02 - Gearbox electronics t  02 - Gearbox electronics, Functions t  02 - Measured values –  Select the value for Gearbox oil temperature (ATF) from the menu. –  Read off ATF temperature.   Caution Risk of damage to gearbox Risk of damage to gearbox t  Select the correct type of ATF → Electronic parts catalogue. Only the ATF available as a replacement part for „multitronic 0AW, front-wheel drive“ may be used in this gearbox. t  The ATF must NOT be mixed with other types of ATF, even in small quantities. Otherwise this could cause malfunctions and/or failure of the gearbox. t  The ATF charging device must be clean and the ATF must not be mixed with other types of oil!

–  Fill reservoir of ATF charging device for CVT gearboxes -VAS 5162- with ATF for „multitronic 0AW, front-wheel drive“; ATF specification → Electronic parts catalogue. –  Secure reservoir for ATF charging device as high as possible on vehicle. l  The stopcock on ATF charging device for CVT gearboxes -VAS 5162- must be closed.

–  Remove O-ring -1- at connection -2- on ATF charging device for CVT gearboxes -VAS 5162-.   Caution There is a risk of filling the gearbox incorrectly. t  The connection -2- must be screwed hand-tight all the way into the ATF inspection hole on the gearbox with the O-ring removed. t  The O-ring must be removed at the connection -2- so that the fluid level pipe in the inspection hole can be pressed into the upper position. t  Only then can the ATF level be checked and topped up correctly.

–  Remove rear noise insulation → General body repairs, exterior; Rep. gr.66.   Note t  Rev engine up to approx. 2500 rpm immediately after starting. t  The engine must be revved up to vent air from the ATF pump. t  The ATF cannot be topped up to the correct level if the engine is not run at increased speed as described. –  Start engine with selector lever in position „P“. –  Press accelerator pedal to rev engine briefly up to 2500 rpm. –  With brake pedal depressed, move selector lever to positions „R“ and „D“ alternately (leave for approx. two seconds in each position with engine running at idling speed). –  Repeat procedure three times. –  With the brake pedal depressed, shift through all selector lever positions („P“, „R“, „N“, „D“, „S“) and hold in each position for approx. 2 seconds (at idling speed).   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).

–  Place used oil collection and extraction unit -V.A.G 1782- below gearbox.   WARNING Risk of eye injury. Wear safety goggles. –  When the ATF has reached a temperature of 35°C, unscrew ATF inspection plug -A-.   Note t  When the plug is opened, approx. 5 to 10 cl of ATF will always run out of the internal fluid level pipe. t  Always adhere to waste disposal regulations.

–  With O-ring removed, screw connection of ATF charging device for CVT gearboxes -VAS 5162- hand-tight all the way into threaded hole for ATF inspection plug.   Note This will push the fluid level pipe into the correct (top) installation position. –  Check ATF level by turning stopcock in direction of drain pipe -lower arrow-. At 35 °C, there should be a flow of ATF from the inspection hole (strong at first, then steady). –  Wait until only a small amount of ATF can be seen emerging.

–  Tighten new ATF inspection plug -A-.   Note Different versions have ATF inspection plugs of different lengths. Always select correct version according to gearbox code letters in → Electronic parts catalogue. To prevent damage to the gearbox, please check the new ATF inspection plug by comparing it with the old one. l  Tightening torque → Item   Note t  ATF inspection plug must be screwed in again at the latest when ATF reaches 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! The ATF level check is now completed. If no ATF (or only a few drops) has emerged from the inspection hole by the time the temperature has reached 40 °C, top up ATF → Anchor.

Filling up ATF l  Engine keeps running at idle speed. –  Turn stopcock in direction of filling hose -lower arrow-. ATF flows into gearbox.

–  Check ATF level by turning stopcock in direction of drain pipe -lower arrow-.   Note Approx. 5 to 10 cl of ATF will always run out of internal fluid level pipe. –  If no additional ATF emerges, turn stopcock back in direction of filler hose and allow some more ATF to flow into gearbox; check ATF level repeatedly. At 35 °C, there should be a flow of ATF from the inspection hole (strong at first, then steady); repeat filling procedure if necessary. –  Wait until only a small amount of ATF can be seen emerging. –  Once correct ATF level has been reached, disconnect ATF charging device for CVT gearboxes -VAS 5162- again.   Note ATF will continue to flow after the connection has been removed.
