6-Cylinder Gasoline Engine

Power Steering Pump Delivery Pressure, Checking

Special tools, testers and auxiliary items required

• Hose Clamps up to 25 mm (3094)

• Power Steering Tester (V.A.G 1402)

• Adapter (V.A.G 1402/2)

• Adapter Set (V.A.G 1402/6)

• Adapter Set (V.A.G 1402/17)

- Clamp off the suction hose using a (3094) - 1 -.






- Remove the screws - 2 - and remove the pressure line from the power steering pump.

- Mount the (V.A.G 1402) and the adapters as illustrated.






1. (V.A.G 1402)

2. Hose from (V.A.G 1402/6)

3. Bolt

4. Pressurized line

5. Adapter (V.A.G 1402/17-2) 1) with elbow (V.A.G 1402/17-3)

6. Power steering pump

7. Adapter (V.A.G 1402/17-1) with (V.A.G 1402/17-3)


1) Replace the (V.A.G 1402/17-1) seal if it is damaged or leaking. Allocation, refer to the Electronic Parts Catalog (ETKA).

• Position the (V.A.G 1402/17-3) on the (V.A.G 1402/17-1) so that the hose from the (V.A.G 1402/6) does not touch the pulley and/or ribbed belt.

• Tighten the union nuts on the (V.A.G 1402/17-3) and the (V.A.G 1402/6) hoses hand-tight with an open-end wrench.

- Remove (3094) from intake hose.

Make sure that lever on pressure gauge stands in position - 2 -.






- Start engine and fill hydraulic fluid in reservoir if necessary.

- Turn the steering wheel approximately 10 times from stop to stop.

- Check the delivery pressure.

Test Prerequisites

• Ribbed belt/ribbed belt tension OK.

• Sealing of system.

• Hoses/lines are not kinked or constricted.

- With engine at idle speed, close stopcock, not more than 5 seconds (position - 1 -) and read pressure.






Specification for Delivery Pressure: 120 to 128 bar

If specified value is not attained, replace power steering pump.

- Remove the pressure gauge and adapter.

- Bleed steering system. Refer to => [ Power Steering System, Bleeding ] Service and Repair.

- Check the hydraulic fluid level and fill if necessary.

- Check the steering system for leaks. Refer to => [ Steering System, Checking for Leaks ] Testing and Inspection.
