Solution

1. Preparation

Gather all necessary tools and parts.
Disconnect the negative terminal of the battery to ensure safety.
Place a drain pan under the power steering system to collect any spilled fluid.

2. Remove Old Power Steering Fluid

Sub-steps:
- Use a turkey baster or fluid siphon to remove old fluid from the reservoir.
- Dispose of the old fluid according to local regulations.

3. Inspect and Replace Leaking Components

Sub-steps:
- If hoses are leaking, use a socket set to remove the clamps and hoses from the power steering pump and steering rack. Replace with new hoses.
- If the power steering pump is leaking, detach the pump from its mounting using the appropriate socket size, disconnect the inlet and outlet hoses, and replace it with a new pump.
- If the steering rack shows signs of leakage, consider replacing the rack or resealing it if feasible.

4. Reassemble and Refill

Sub-steps:
- Reattach all hoses and clamps securely, ensuring no cross-threading.
- Reinstall the power steering pump and tighten to manufacturer specifications (usually around 18-25 ft-lbs).
- Refill the power steering reservoir with the correct fluid (usually CHF 11S for VW models).

5. Bleed the Power Steering System

Sub-steps:
- Start the engine and turn the steering wheel from lock to lock several times to remove air from the system.
- Check the fluid level and top off as necessary while ensuring no air bubbles are present.
