Removing and installing power steering pump (vehicles with 4-cylinder diesel engine, vehicles with dynamic steering) — AUDI

🧭 Before you start

Fits: Audi Q5 (8R, 2008–2017); platform code 83

• Opens: power steering fluid
• Special tools named: 3320, T10172/5
• Renewed: gaskets

Don't miss

• First slacken (but do not remove) bolts (arrow) for pulley using door alignment tool3320 and corresponding bit 3320/2. If necessary, use counterhold tool T10172 with adapter T10172/5(1).
• When fitting the pressure line (4), make sure the angle between the pipe connection and the shaft of the power steering pump is approx. 90°.
• Align marking on pulley (arrow) (made previously) with marking on hub.
• Ensure that the belt is properly seated in the pulleys when installing.

📋 Procedure

1. Raise vehicle on lifting platform.
2. Lift off engine cover panel (arrows).
3. Unfasten clips (arrows) and detach toothed belt cover.
4. Mark position of pulley relative to hub (arrow). [Note: If the power steering pump is being renewed, transfer the marking on the hub from the old pump to the new pump.Due to limited space, it is not possible to see the positions of the holes in the pulley relative to the holes in the hub during installation.] [Note: Before removing poly V-belt, mark direction of rotation. A used belt can break if it runs in the opposite direction. Ensure that the belt is properly seated in the pulleys when installing.]
5. Detach poly V-belt only from power steering pump pulley 13Cylinder block (pulley end); Removing and installing poly V-belt.

6. First slacken (but do not remove) bolts (arrow) for pulley using door alignment tool3320 and corresponding bit 3320/2. If necessary, use counterhold tool T10172 with adapter T10172/5(1).
7. Now remove slackened bolts and detach belt pulley.
8. Extract hydraulic fluid from reservoir with used oil collection and extraction unitV.A.G 1782.
9. Clamp off suction hose (1) and return hose (2) using hose clamps up to ∅ 25 mm3094.
10. ⚠ Hose clamps up to ∅ 25 mm3094 must not be applied at any point near the non-return valve in the return hose (2). The non-return valve will otherwise be damaged.The non-return valve is located in the return hose (2) between the hose clips (arrows). — Release hose clips (arrows) and remove air hose.
11. Remove noise insulation General body repairs, exterior66Noise insulation.
12. Place drip tray underneath power steering pump.
13. If fitted, carefully cut through cable tie (1) for wiring harness (2).
14. Detach hose clip (4) from suction hose (3). Pull off suction hose (3).
15. Place several cloths beneath power steering pump and pressure line.
16. Unscrew union nut (1) and pull pressure line (4) out of power steering pump.
17. Seal off connections of power steering pump and lines with clean plugs.
18. If fitted, move wiring harness (2) clear at power steering pump.
19. Remove bolts (1) (3x) and bolt (3).
20. To install power steering pump, drive back sleeve (2) for bolt (3) slightly at bracket.
21. Take out power steering pump. [Note: Renew gaskets and seals.Before fitting a new power steering pump, put in hydraulic fluid at the inlet and turn pump by hand until fluid flows out at the pressure outlet.Secure all hose connections with new hose clips Electronic parts catalogue.]
22. Note correct position of suction hose on power steering pump.
23. Note installation dimensions of hose clip. Dimension (a) should be 4 mm.
24. Turn hub by hand until fluid comes out at pump outlet.
25. Fit power steering pump into bracket.
26. First screw in front bolts (1) (3x) loosely.
27. Then screw in rear bolt (3) loosely.
28. First tighten bolts (1) and then bolt (3).
29. Insert pressure line (4) into power steering pump (5) as far as stop. Then tighten union nut (1). [Note: When fitting the pressure line (4), make sure the angle between the pipe connection and the shaft of the power steering pump is approx. 90°.]
30. Push suction hose onto connection and attach a new hose clip (3).
31. Clean off fluid in engine compartment where necessary.
32. Align marking on pulley (arrow) (made previously) with marking on hub.
33. Tighten bolts (arrows) for belt pulley.
34. Check hydraulic fluid level .
35. Bleed steering system .
36. Check steering system for leaks .
37. Install noise insulation General body repairs, exterior66Noise insulation.
38. Install poly V-belt and make sure that belt runs straight 13Cylinder block (pulley end); Removing and installing poly V-belt drive. [Note: Ensure that the belt is properly seated in the pulleys when installing.]
39. Start engine and check that belt runs properly.
