Solution

1. Preparation

Gather required tools and parts.
Ensure the vehicle is parked on a level surface and the engine is turned off.
Wear safety gloves and goggles for protection.

2. Locate Power Steering Fluid Reservoir

Open the hood and locate the power steering fluid reservoir. Refer to the owner’s manual if necessary.
Clean the area around the reservoir cap to prevent contamination.

3. Check and Refill Fluid

Remove the reservoir cap slowly to avoid fluid spillage.
Using a clean funnel, add the recommended power steering fluid (typically CHF 11S for BMW) to the reservoir until it reaches the "MAX" level indicator.
Replace the reservoir cap securely.

4. Bleed the Power Steering System (if necessary)

Start the engine and turn the steering wheel from lock to lock several times to help purge any air from the system.
Check the fluid level again and add more if necessary.
Inspect for any leaks during this process.
