Solution

1. Preparation

Gather necessary tools: clean cloth and flashlight.
Ensure the vehicle is on level ground and the engine is off.

2. Locate the Brake Fluid Reservoir

Identify the brake fluid reservoir by referring to the owner’s manual if necessary.
Ensure the area around the reservoir is clean to prevent contamination.

3. Check Fluid Level

Visually inspect the brake fluid level through the transparent walls of the reservoir.
The fluid should be between the minimum and maximum lines.
Use a flashlight if needed to get a clearer view.

4. Add Brake Fluid (if necessary)

If the fluid level is below the minimum line, remove the cap of the brake fluid reservoir.
Using a funnel, add the appropriate type of brake fluid (DOT 4 is commonly used in BMWs).
Fill to the maximum line without overfilling.

5. Clean Up and Recheck

Wipe any spills immediately with a clean cloth to prevent damage to paint or components.
Reinstall the cap securely on the reservoir.
Close the hood and ensure all tools are removed from the engine bay.
