Solution

1. Preparation

Gather tools: socket set, torque wrench, OBD-II scanner, fluid catch pan, and safety gloves.
Ensure the vehicle is parked on a level surface and the engine is off.
Disconnect the battery to avoid any electrical issues.

2. Check Power Steering Fluid

Locate the power steering reservoir.
Remove the cap and check the fluid level against the markings on the reservoir.
If low, add the recommended power steering fluid (usually CHF 11S for Volkswagen).
Inspect the fluid for contamination (dark color or debris); if contaminated, proceed to fluid replacement.

3. Inspect for Leaks

Clean the area around the power steering components.
Use a flashlight to inspect hoses and connections for signs of leaks.
If leaks are found, replace the affected hoses or seals.

4. Examine the Power Steering Pump

Remove the serpentine belt by loosening the tensioner pulley.
Inspect the power steering pump for any physical damage or noise when manually rotating the pulley.
If the pump is faulty, replace it with a new unit.

5. Inspect Steering Rack

Lift the vehicle using a jack and secure it with jack stands.
Check the steering rack for any signs of wear or damage.
If necessary, replace the steering rack, ensuring to align the tie rods properly during installation.

6. Reassemble Components

Reinstall the serpentine belt if it was removed.
Reattach the battery and ensure all connections are secure.
Refill the power steering fluid to the appropriate level.
