Ensure lever on pressure gauge stands in the open position - 1 -.
Start engine without giving gas.
Turn steering wheel from lock to lock about 10 times.
Switch off engine and, if needed, top off hydraulic fluid in reservoir.

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

Check delivery pressure.

Fig 7: Ensuring Lever On Pressure Gauge Stands In Open/Closed Position

Start engine and close shut-off valve to the closed position - 2 - while engine is idling and read pressure (lever must face away from pressure hose). Do not perform measurement longer than 10 seconds.

Specification for delivery pressure: 123 to 130 bar

If pressure is not to specification, replace pump → Power steering pump (vehicles with 8-cylinder gasoline engine with chain drive), removing and installing .

Switch off engine.
Remove Power steering test unit V.A.G 1402.
Tighten connection for pressure hoses to 40 Nm.
Check power steering fluid level → Power steering fluid level, checking .

Check steering system for leaks → Steering system, checking for leaks .
