Solution

1. Preparation

Gather necessary tools: a clean lint-free cloth and possibly a funnel for adding fluid.
Ensure the vehicle is parked on a level surface.

2. Check Fluid Level

Locate the power steering fluid reservoir, which is typically near the engine's front on the driver's side.
If a dipstick is present, remove it and wipe it clean to avoid contamination.
Reinsert the dipstick fully into the reservoir and remove it again to check the fluid level.
If the fluid level is low, proceed to add fluid.

3. Add Power Steering Fluid

If the fluid level is below the "MIN" mark, remove the cap from the power steering fluid reservoir.
Using a funnel, add the appropriate type of power steering fluid as specified in the owner’s manual (usually CHF 11S for BMW).
Fill slowly and check the level frequently to avoid overfilling.
Replace the cap securely after filling.

4. Check for Leaks

After topping off the fluid, visually inspect the power steering hoses and connections for any signs of leaks.
Start the engine and turn the steering wheel from lock to lock to circulate the new fluid, checking for any abnormal noises or issues.
