Don't miss

• The drain plug for gear oil (MTF) is located behind the tunnel cross member.
• Risk of damage to gearboxIf there is no gear oil (MTF) in the gearbox (or not enough oil):The engine must not be started.The vehicle must not be towed. — If fitted, remove bolts (arrows) and detach air deflector (A).
• Items marked (1) and (arrow) can be disregarded.The in-line ATF filter must be pressed to the side for access to the filler and inspection plug for gear oil (MTF).
• Risk of eye injury.Wear safety goggles. — Unscrew filler and inspection plug (arrow) at side of gearbox housing.
• Make sure to wait the required amount of time so that the various oil chambers in the gearbox are filled evenly.

📋 Procedure

1. Remove rear noise insulation (2)General body repairs, exterior66Noise insulation; Removing and installing noise insulation.
2. Place used oil collection and extraction unitVAS 6622 below gearbox. [Note: 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.In the following description, vehicles with drain plug for gear oil (MTF) are differentiated from vehicles that are fitted with gearbox oil temperature sender 2G754 instead of drain plug for gear oil (MTF).]
3. ⚠ Risk of eye injury.Wear safety goggles. — Place suitable cloth on tunnel cross member. [Note: The drain plug for gear oil (MTF) is located behind the tunnel cross member.]
4. Unscrew drain plug for gear oil (MTF) (arrow) under gearbox housing.
5. Drain gear oil (MTF).

6. Tighten drain plug for gear oil (MTF) (arrow).
7. Switch off ignition. [Note: Always switch off ignition before unplugging connector at gearbox oil temperature sender 2G754. If the ignition is on, the gearbox reverts to a backup programme. This increments the counter for high temperature operation, and after 10 minutes an entry is recorded in the event memory of the automatic gearbox control unit J217.]
8. Unplug connector (2) from gearbox oil temperature sender 2G754, move clear to the top and tie up. [Note: Keep gear oil away from connector (2) and contacts on gearbox oil temperature sender 2G754. The connector contacts must be cleaned immediately if they come into contact with gear oil (MTF). The gear oil (MTF) causes contact problems in the connector contacts.]
9. Unscrew gearbox oil temperature sender 2G754(1).
10. Drain gear oil (MTF).
11. Tighten gearbox oil temperature sender 2G754(1) and plug in connector (2).
12. ⚠ Risk of damage to gearboxIf there is no gear oil (MTF) in the gearbox (or not enough oil):The engine must not be started.The vehicle must not be towed. — If fitted, remove bolts (arrows) and detach air deflector (A).
13. Set up gearbox support T10337 on engine and gearbox jackV.A.G 1383 A and position underneath gearbox.
14. 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.]
15. Remove tunnel cross member .
16. Remove bolts (2) and press in-line ATF filter to side. [Note: Items marked (1) and (arrow) can be disregarded.The in-line ATF filter must be pressed to the side for access to the filler and inspection plug for gear oil (MTF).] [Note: 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.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.]
17. Place suitable cloth on tunnel cross member.
18. Place used oil collection and extraction unitVAS 6622 below gearbox.
19. ⚠ Risk of eye injury.Wear safety goggles. — Unscrew filler and inspection plug (arrow) at side of gearbox housing.
20. Using hand pump for gear oilVAS 6617, fill up with gear oil (MTF) until oil comes out at filler and inspection hole.
21. Repeat the procedure, adding 50 ml of 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.]
22. Tighten plug. [Note: The level does not need to be re-checked after this step.]
23. Screw in bolts (2).
24. Install tunnel cross member . [Note: On vehicles not equipped with an in-line ATF filter at the rear left of the gearbox the tunnel cross member must be cleaned.Any gear oil (MTF) which has run into the casting pockets on the tunnel cross member must be removed completely.]
25. Remove cloth on tunnel cross member.
26. Clean tunnel cross member and remove any remaining gear oil.
27. After changing gear oil, perform "“Guided Function”"02 - Reset temperature counter (G754) using vehicle diagnostic tester.
