Solution

1. Preparation

Gather all necessary tools and parts before beginning the repair.
Disconnect the negative terminal of the battery to avoid any electrical shorts.

2. Check Power Steering Fluid

Remove the power steering fluid reservoir cap.
Inspect fluid level; if low, top off with the recommended fluid (VW G004000).
If fluid is contaminated, proceed to replace the fluid.

3. Inspect Power Steering Pump

Locate the power steering pump and check for leaks or damage.
If leaks are found, replace the power steering pump.
Remove the pump by disconnecting the fluid lines and mounting bolts.

4. Inspect Steering Rack

Examine the steering rack for signs of wear or failure.
If the steering rack is damaged, it will need to be replaced.
Disconnect the tie rods from the steering rack and remove the mounting bolts.

5. Reassemble and Refill

Reinstall the steering rack and power steering pump.
Reconnect all electrical connectors and fluid lines securely.
Refill the power steering fluid reservoir with the appropriate fluid.

6. Test the System

Reconnect the negative terminal of the battery.
Start the engine and turn the steering wheel from lock to lock to bleed air from the system.
Check for any leaks around the power steering components.
