Reset Brake Fluid Light BMW: Method Steps

To reset the brake fluid light on a BMW, follow these general steps. Note that the exact procedure may vary slightly depending on your BMW model and year, but these steps will work for most BMW vehicles with an electronic brake fluid light system.

1. Check Brake Fluid Level:

Reset Brake Fluid Light BMW: Before resetting the light, ensure that your brake fluid level is at the proper level. If the fluid is low, top it up with the recommended brake fluid for your vehicle. If the fluid is contaminated or old, it might be a good idea to replace it before resetting the light.

2. Insert the Key/Turn on Ignition:

Place the key in the ignition and turn it to the “On” position (without starting the engine). In newer BMW models with keyless entry, press the start button without pressing the brake pedal.

3. Press the Brake Pedal:

Depress the brake pedal fully. Some models require you to do this for the reset to work.

4. Press and Hold the Odometer Reset Button:

Locate the odometer reset button (usually found on the dashboard near the speedometer). Press and hold this button for approximately 10-15 seconds. You may need to press it multiple times on some models or hold it down longer.

5. Watch for the Reset Procedure:

While holding the reset button, the brake fluid light on your dashboard should begin to flash and then turn off once the reset is complete.

6. Turn Off Ignition:

Once the light has been reset, turn off the ignition and start the car as usual. The brake fluid light should remain off.

7. Test the System:

After resetting the light, check if the brake fluid level remains stable and the light does not return. If it does, there may be an issue with the brake fluid system or a sensor.

8. If the Light Stays On:

If the brake fluid light continues to stay on after performing the reset, it could indicate that the fluid level is still low, there is air in the brake lines, or there is a sensor malfunction. In this case, a thorough inspection by a mechanic is advised.

Common Tips:

• Ensure you are using the correct type of brake fluid as specified in the owner's manual.
• If your vehicle is equipped with a "CBS" (Condition-Based Service) system, the brake fluid service may also need to be reset through the vehicle's computer using an OBD-II scanner.
• On some newer BMWs, you might need to use a special tool or diagnostic equipment to reset the brake fluid light.

Always consult your owner's manual for any specific instructions related to your BMW model. If you're unsure about the process or any warning lights, it's always best to consult a professional mechanic.
