🧭 Before you start

Fits: Audi A3 (8P, 2003–2012), Audi TT Mk2 (8J, 2006–2014)

• Special tools named: puller

Don't miss

• Risk of damage to flexible joints in exhaust system.The flexible joint in the front exhaust pipe must not be bent further than 10°. — Disconnect exhaust system at clamp (arrows).
• Make sure axial needle bearings (5 ... 7) do not move out of their centred position when fitting housing.
• Before installing, lightly oil outer circumference of new oil seal and space between sealing lips with high performance oil for Haldex coupling.
• Drive in new oil seal as far as stop using thrust piece T10019. Make sure seal remains straight.

📋 Procedure

1. ⚠ Risk of damage to flexible joints in exhaust system.The flexible joint in the front exhaust pipe must not be bent further than 10°. — Disconnect exhaust system at clamp (arrows).
2. Tie up front exhaust pipe on underbody.
3. Remove rear section of exhaust system: Audi A3 Engine, mechanics26; Audi TT 26Exhaust pipes/silencers; Exploded view - silencers.
4. Remove flexible coupling (rear) .
5. Unscrew hexagon nut for propshaft flange.

6. Pull off propshaft flange. Use three-arm puller (e.g. Kukko 12-1) if flange is difficult to remove.
7. Pull seal out with oil seal extractor lever VW 681.
8. Remove Haldex coupling .
9. Place Haldex coupling on a clean workbench.
10. Detach housing for Haldex coupling
11. Remove circlip (1) in front of grooved ball bearing (2).
12. Press out grooved ball bearing.
13. Carefully press new grooved ball bearing in until stop.
14. Fit circlip (1).
15. Heat grooved ball bearing (2) to approx. 80 ℃ using hot air blowerV.A.G 1416.
16. Position axial needle bearings (5 ... 7) on the centre of multi-plate clutch (1)“Assembly of multi-plate clutch”.
17. Fit Haldex coupling housing onto multi-plate clutch (1) by hand. [Note: Make sure axial needle bearings (5 ... 7) do not move out of their centred position when fitting housing.]
18. Before installing, lightly oil outer circumference of new oil seal and space between sealing lips with high performance oil for Haldex coupling.
19. Drive in new oil seal as far as stop using thrust piece T10019. Make sure seal remains straight.
20. Press on propshaft flange.
21. Apply locking fluidD 000 600 to new hexagon nut and tighten nut. Tightening torque
22. Install Haldex coupling .
23. Install flexible coupling (rear) .
24. Install exhaust system and align so it is free of stress: Audi A3 Engine, mechanics26; Audi TT 26Exhaust pipes/silencers; Exploded view - silencers.
25. Fill up with high-performance oil for Haldex coupling and check oil level in Haldex coupling .
