Checking delivery pressure of power steering pump (vehicles with 6-cylinder FSI petrol engine) — AUDI

🔩 Torque settings

Values can differ between engine variants — check the code stamped on your block.

ℹ️ Always cross-check the exact figure against your vehicle's factory manual before final tightening — a wrong torque can damage the engine. These values are extracted from workshop data and may not cover every variant or revision.

📋 Procedure

1. Detach engine cover panel.
2. Position vehicle on lifting platform .
3. Remove noise insulation 50.
4. Drain coolant 19.
5. Remove air conditioner compressor 87.

6. Clamp off suction hose and return hose at reservoir using hose clamps3094.
7. Place a cloth under the union to catch escaping hydraulic fluid.
8. Unscrew banjo bolt (2) and disconnect pressure hose (1) from power steering pump.
9. Connect power steering testerV.A.G 1402 as shown.
10. Remove hose clamps3094.
11. Make sure lever on pressure gauge is in position (2).
12. Start engine but do not press accelerator.
13. Turn steering wheel approx. 10 times from lock to lock.
14. Switch off engine and top up hydraulic fluid in reservoir if necessary. [Note: To avoid damaging the pump, please note the following points:Cut-off valve of pressure gauge must not remain closed for more than 10 seconds during this test.Start engine without pressing accelerator and leave it running at idling speed.Take pump pressure reading at idling speed immediately after starting engine (have second mechanic take reading).The pressure will drop during the test; take the highest pressure reading as the test value.]
15. Then check delivery pressure.
16. Start engine, close cut-off valve (position (1)) with engine idling and read off pressure. Do not leave cut-off valve closed for longer than 10 seconds.
17. Switch off engine.
18. Remove power steering testerV.A.G 1402.
19. Install banjo bolt and tighten to 47 Nm. — 47 Nm (35 lb-ft)
20. Install air conditioner compressor 87.
21. Bleed steering system .
22. Check hydraulic fluid level .
23. Check steering system for leaks .
24. Fit noise insulation 50.
25. Set down vehicle on its wheels .
