Solution

1. Preparation

Gather all necessary tools and parts.

Locate the power steering fluid reservoir (refer to owner's manual for exact location).
Remove the cap and check the fluid level against the dipstick.
If low, add the recommended type of power steering fluid (Porsche-approved fluid).
Replace the cap securely.

3. Inspect the Power Steering Pump

Locate the power steering pump, usually driven by the serpentine belt.
Check for any fluid leaks around the pump and hoses.
If leaks are found, replace the power steering pump and/or hoses as necessary.

4. Check the Steering Rack

Inspect the steering rack for any signs of damage or fluid leaks.
If the steering rack is leaking, it will need to be replaced.
Properly align and secure all connections upon installation.

Reconnect the negative battery terminal.
Start the vehicle and turn the steering wheel from lock to lock to bleed any air from the system.
Take the vehicle for a test drive to ensure smooth steering operation.
