Vehicles with 4-cylinder 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
- Hose clamps up to 25 mm dia. 3094
- Power steering test unit V.A.G 1402
- Adapter V.A.G 1402/3
- Clamp off suction and return line using hose clamps Hose Clamps Up to 25 mm dia. 3094.
- Remove pressure hose from power steering pump.
- Screw adapter V.A.G 1402/3 into power steering pump in place of banjo bolt.
NOTE:
- If adapter V.A.G 1402/3 threads are too long, use more seals.
- Screw pressure gauge V.A.G 1402 hose on adapter V.A.G 1402/3.
- Close gauge shut-off valve (lever to left).
- Remove hose clamps up to 25 mm dia. 3094.
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 |
|---|---|---|
| 4-cylinder gasoline engines | 8E0 145 153 B 8E0 145 153 8E0 145 155 L | 110 to 118 110 to 118 110 to 118 |
If pressure is not to specification, replace pump → Power steering pump, removing and installing .
- Switch off engine.
- Remove pressure gauge.
- Connect pressure line to power steering pump with banjo bolt.
- 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
