Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and turn off the engine.
Disconnect the negative battery terminal to prevent electrical issues.

2. Check and Refill Power Steering Fluid

Locate the power steering fluid reservoir (usually marked with a steering wheel icon).
Remove the cap and check the fluid level against the dipstick or markings on the reservoir.
If low, add the appropriate power steering fluid as specified in the owner’s manual (typically CHF 202 or equivalent).

3. Inspect Power Steering Pump

Reconnect the battery.
Start the engine and listen for any unusual noises from the power steering pump.
If the pump is noisy or not functioning, replace the power steering pump:
- Tools Required: Socket set, wrench set, fluid catch pan.
- Sub-steps:
  1. Disconnect the hoses from the power steering pump.
  2. Remove the mounting bolts securing the pump to the engine.
  3. Install the new pump and tighten bolts to the manufacturer's torque specifications (usually around 25 Nm).
  4. Reconnect the hoses and ensure no leaks are present.

4. Inspect Steering Rack and Pinion

If the power steering pump is functioning, inspect the steering rack:
- Tools Required: Socket set, wrench set, jack stands.
- Sub-steps:
  1. Lift the front of the vehicle using a jack and secure it on jack stands.
  2. Visually inspect the steering rack for leaks or damage.
  3. If damaged, disconnect the steering linkage from the rack and remove the mounting bolts.
  4. Replace with a new steering rack and torque the bolts to specifications (usually around 50 Nm).
  5. Reconnect the steering linkage.

5. Final Checks

Refill the power steering fluid reservoir if it was drained during repairs.
Start the engine and turn the steering wheel from lock to lock to bleed the system of air bubbles.
Check for leaks around the power steering pump and steering rack.
