Servicing air pipe — AUDI

📋 Procedure

1. Clean sections in vicinity of connection piece and relevant cutting location.
2. Cut through air pipe at cutting location (at a right angle) using cutting pliersVAS 6228.
3. Unscrew connection piece and remove air pipe.
4. Then use waterproof pen to mark end of air pipe in vehicle and both ends of new air pipe.
5. Fit sponge rubber insulation to both pipes.

6. Fit new pipe connector. [Note: The connection pieces in the pipe connector are already tightened to torque. The air pipes only need to be pushed in.]
7. Remove transport protection cap.
8. Push old air pipe through seals (1) and (2).
9. Then push air pipe through sealing edges (3) and (4) of cutting ring in pipe connector as far as stop (5), exerting more force as required.
10. Fit sponge rubber insulation over connection pieces.
11. Repeat this procedure with the new pipe.
12. Renew connection piece .
13. Release original air pipe (2) from wiring harness (3).
14. Sheathe wiring harness again in the proper manner.
15. Service air pipe .
16. Secure sheathed pipe connector (1) and new air pipe (4) to wiring harness with cable ties. [Note: Route new air pipe (5) in a wide arc, as shown in illustration.]
17. Release original air pipe (3) from wiring harness (4).
18. Sheathe wiring harness again in the proper manner.
19. Service air pipe .
20. Secure sheathed pipe connector (2) and new air pipe (5) to air pipe leading to accumulator (1) and to wiring harness (4) with cable ties. [Note: If air pipes are damaged at the solenoid valve block, the cutting location must be positioned in the vehicle interior (spare wheel well) because of the short pipe lengths.Route new air pipe through opening (1) in spare wheel well to solenoid valve block.]
21. Release original air pipe from wiring harness (3).
