Solution

1. Preparation

Gather necessary tools: flashlight (if needed for visibility) and a clean cloth.
Ensure the vehicle is parked on a level surface and the engine is off.

2. Locate and Inspect the Brake Fluid Reservoir

Open the hood and secure it properly.
Locate the brake fluid reservoir; it is usually a translucent plastic container with a black cap.
Clean the area around the reservoir cap to avoid dirt entering the system.

3. Check Brake Fluid Level

Carefully remove the cap from the brake fluid reservoir.
Visually inspect the fluid level against the "MIN" and "MAX" markings on the side of the reservoir.
- If the level is below the "MIN" mark, it indicates a need for fluid replenishment.

4. Assess Brake Fluid Condition

Check the color and clarity of the brake fluid. Fresh fluid is typically yellow or clear.
If the fluid appears dark, contaminated, or has particles, it may need to be replaced.

5. Refill Brake Fluid (if necessary)

If the fluid level is low, add the recommended brake fluid type (usually DOT 4 for BMW) until it reaches the "MAX" mark.
Avoid overfilling, which can cause pressure buildup in the system.

6. Replace Cap and Clean Up

Securely replace the cap on the brake fluid reservoir.
Wipe any spills or drips from the reservoir area with a clean cloth.
Close the hood securely.
