Pressure checking
- Remove cover for power steering fluid reservoir.
- Pinch off intake line using 3094 hose clamp.
- Unbolt expansion hose from power steering pump.
- Install VAG 1402/3 adapter on power steering pump in place of the banjo bolt.
- Install hose from VAG1402 pressure gauge on VAG 1402/3 adapter.
- Close shut-off valve on pressure gauge (lever faces toward left).
- Remove 3094 hose clamp and add fluid to power steering fluid reservoir if necessary.
Check pressure:
NOTE:
To avoid damaging pump, note the following:
- Do not allow engine to run more than 10 seconds during the test.
- Start engine without depressing the accelerator pedal and let engine idle.
- Make a note of pressure immediately after starting engine when it is idling (this may require a second technician).
- As pressure drops during check, the highest pressure is definitive.
Specification: 120-130 bar
- Turn engine off.
If specification is not obtained, replace the power steering pump. See POWER STEERING PUMP, REMOVING AND INSTALLING .
- Check fluid level. See POWER STEERING FLUID LEVEL, CHECKING; STEERING SYSTEM, BLEEDING AND CHECKING FOR LEAKS .
- Bleed steering system. See STEERING SYSTEM, BLEEDING .
- Check steering system for leaks. See STEERING SYSTEM, CHECKING FOR LEAKS .
