Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a level surface and turn off the engine.
Disconnect the battery to ensure safety while working on the electrical system.

2. Check and Refill Power Steering Fluid

Tools Required: Funnel, clean rag
Locate the power steering fluid reservoir.
Remove the cap and check the fluid level against the markings.
If low, add the recommended power steering fluid (usually CHF 202 or similar) until it reaches the proper level.
Replace the cap securely.

3. Inspect and Repair Leaks

Tools Required: Wrench set, flashlight
Examine all power steering hoses and connections for signs of leaks.
If leaks are found, replace damaged hoses or tighten loose connections.
Use a clean rag to wipe any spilled fluid to prevent slipping hazards.

4. Test and Replace Power Steering Pump (if necessary)

Tools Required: Socket set, torque wrench
Disconnect the power steering pump from its electrical and fluid connections.
Remove the mounting bolts and carefully take out the pump.
Install the new pump by reversing the removal procedure. Use a torque wrench to tighten bolts to the manufacturer's specifications (usually around 20 Nm).
Reconnect the fluid lines and electrical connector.

5. Bleed the Power Steering System

Tools Required: Clean power steering fluid
With the engine running, turn the steering wheel from lock to lock several times to remove air from the system.
Check the fluid level again and top up if necessary.
