Vehicles with 6-cylinder gasoline engine
WARNING: This page does not describe the selected car, but rather 17 other vehicles, including the 2009 Audi S4, 2009 Audi A4, 2008 Audi S4, 2008 Audi RS 4, and 2008 Audi A4. However, it is still accessible from the selected car via links, so may be relevant.
Special tools, testers and auxiliary items required
- Power steering test unit V.A.G 1402
- Remove engine cover.
- Disconnect extension hose - arrow - while counterholding extension hose hex head.
NOTE:
- Place a cloth under separation point to absorb escaping hydraulic oil.
- Remove hydraulic line bracket if necessary to make work easier.
- Screw pressure gauge V.A.G 1402 hose onto extension hose.
- Close gauge shut-off valve (lever to left).
NOTE:
- To avoid damage to pump, observe the following:
- Pressure gauge shut-off valve must not remained closed longer than 10 seconds during this test.
- Start engine without giving gas and run at idle.
- Read pump pressure immediately after starting at idle speed (have it read by second technician, if necessary).
- Because pressure falls over the course of the test, the highest pressure shown is the decisive measurement.
- Start engine and top off fluid level in reservoir if necessary.
- At idle speed, read off pressure on pressure gauge (measurement no longer than 10 seconds).
Pump pressure specified value (positive pressure)
| Engine | Pump | Pump pressure (bar |
|---|---|---|
| 6-cylinder gasoline engines | 8E0 145 155 E 8E0 145 155 F 8E0 145 155 P | 120 to 127 120 to 127 120 to 127 |
If pressure is not to specification, replace pump → Power steering pump, removing and installing .
- Switch off engine.
- Remove pressure gauge.
- Connect extension hose while counterholding hose hex head.
- Check power steering fluid level → Power steering fluid level, checking .
- Check steering system for leaks → Steering system, checking for leaks .
- Bleed steering system → Steering system, bleeding after reconstructing
