Special tools and workshop equipment required

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

t	Engine and gearbox jack -V.A.G 1383 A-

t	Gearbox support -T10337-

t	Hand pump for gear oil -VAS 6617-

t	Safety goggles

Procedure   Note t  → Chapter „Repair instructions“. t  → Chapter „Rules for cleanliness when working on the dual clutch gearbox“. t  Always use the correct fluid for the different parts of the gearbox: gear oil (MTF) system and ATF system. l  Gear oil about 20 °C (room temperature). l  Vehicle must be absolutely horizontal (drive it onto a four pillar lifting platform or over an inspection pit). l  The hand pump for gear oil -VAS 6617- must be clean; flush out with gear oil (MTF) if necessary. The oil must not be mixed with other lubricants. l  The vehicle must be stationary with the engine switched off for at least 15 minutes to allow the oil level to stabilise. –  Remove rear noise insulation -2- → General body repairs, exterior; Rep. gr.66.

Vehicles with in-line ATF filter -arrow- at rear left of gearbox:

–  Set up gearbox support -T10337- on engine and gearbox jack -V.A.G 1383 A- and position underneath gearbox. –  Raise gearbox slightly.   Note If the tunnel cross member is being removed in order to check or top up the gear oil level (MTF), the gearbox must be brought back to the normal position after the tunnel cross member is removed. Only then can the gear oil level be topped up correctly. –  Remove tunnel cross member → Chapter.

–  Remove bolts -2- and press in-line ATF filter to side.   Note t  Items marked -1- and -arrow- can be disregarded. t  The in-line ATF filter must be pressed to the side for access to the filler and inspection plug for gear oil (MTF). Vehicles not equipped with in-line ATF filter at rear left of gearbox:   Note t  On vehicles not equipped with an in-line ATF filter at the rear left of the gearbox the tunnel cross member does not have to be removed. t  A cloth should be placed on the tunnel cross member to prevent gear oil (MTF) from running into the casting pockets on the tunnel cross member. –  Place suitable cloth on tunnel cross member.

All vehicles: –  Place used oil collection and extraction unit -V.A.G 1782- below gearbox.   WARNING Risk of eye injury. Wear safety goggles. –  Unscrew filler and inspection plug -arrow- at side of gearbox housing. l  Gear oil level (MTF) must be up to bottom lip of filler and inspection hole. If gear oil level (MTF) is not up to bottom lip of filler and inspection hole: –  Using hand pump for gear oil -VAS 6617-, fill up slowly with gear oil (MTF) until oil comes out at filler and inspection hole. l  Gear oil (MTF) specifications → Electronic parts catalogue –  Repeat the procedure in several steps by adding gear oil (MTF) every 15 seconds until the gearbox will not take any more oil.   Note Make sure to wait the required amount of time so that the various oil chambers in the gearbox are filled evenly. –  Tighten plug. l  Tightening torque → Chapter „Exploded view - drain and inspection plugs for gear oil (MTF) in gearbox“ The remaining installation steps are carried out in reverse sequence; note the following:

Vehicles with in-line ATF filter -arrow- at rear left of gearbox: –  Screw in bolts -2-. l  Tightening torques → Chapter „ATF cooler, ATF lines and ATF filter“ –  Install tunnel cross member → Chapter. Vehicles not equipped with in-line ATF filter at rear left of gearbox:   Note t  On vehicles not equipped with an in-line ATF filter at the rear left of the gearbox the tunnel cross member must be cleaned. t  Any gear oil (MTF) which has run into the casting pockets on the tunnel cross member must be removed completely. –  Remove cloth on tunnel cross member. –  Clean tunnel cross member and remove any remaining gear oil.
