Diagnostic Steps

1
Park the vehicle on a level surface and turn off the engine.
2
Open the hood and locate the power steering reservoir.
3
Inspect the reservoir for any visible markings indicating fluid level.
4
If applicable, remove the cap to check the fluid level against the dipstick or markings.
5
Observe the color and texture of the fluid to check for contamination.

Solution

1. Preparation

Ensure the vehicle is parked on a flat surface.
Wear gloves and safety glasses for protection.

2. Locate the Power Steering Reservoir

Open the hood and secure it.
Identify the power steering reservoir; it is typically located near the engine and marked with a steering wheel icon.

3. Check the Fluid Level

If the reservoir has a dipstick attached to the cap, remove the cap and wipe the dipstick clean.
Insert the dipstick back into the reservoir without threading it in, then remove it again to check the fluid level against the markings.
If the reservoir has markings on the side, simply observe the fluid level against the “MIN” and “MAX” lines.

4. Add Power Steering Fluid (if necessary)

If the fluid level is below the "MIN" mark, add the recommended power steering fluid until it reaches the "MAX" mark.
Use only the fluid specified in the owner’s manual (typically CHF 11S fluid for BMW vehicles).

5. Replace the Cap

Ensure the cap is securely fastened to prevent contamination.
Close the hood properly.
