Solution

1. Preparation

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

2. Access the Brake Fluid Reservoir

Open the hood of the BMW X3 F25.
Secure the hood using the prop rod.

3. Check Brake Fluid Level

Locate the brake fluid reservoir, which is usually a transparent plastic container.
Inspect the fluid level against the min and max markings on the reservoir.
If the fluid level is below the minimum line, it indicates a need for a top-up.

4. Add Brake Fluid (if necessary)

If the fluid level is low, use only the recommended brake fluid (typically DOT 4 for BMW).
Clean the area around the reservoir cap thoroughly before opening it.
Remove the cap and use a funnel to add brake fluid to the correct level.
Replace the cap securely after adding fluid.
