How to Reset the BMW Service Light
1. Put the key in the ignition, and turn it one notch so the BMW dashboard illuminates, but do not turn on the engine.
2. Notice which service icon on the dashboard is illuminated in red. The service light indicates services that are not working properly, which may include brake pads or the engine-cooling fan.
3. Locate the button labeled 'BC' on the stick used to turn the headlights of the car on and off. This stick is located on the left side of the base of the steering wheel.
4. Press the 'BC' button once. A clock should appear on the dashboard.
5. Locate the small button located to the left and below the odometer on the BMW dashboard. Press this button and hold it down until the failed service light on the dashboard is illuminated in red again.
6. Press the 'BC' button one time. You should see the word 'Reset' appear on the dashboard.
7. Push the 'BC' button again and hold it down until you see the failed service light reappear on the dashboard. The icon for the service should be orange instead of red, which means the service warning light has been reset.
8. Locate the scroll button on the stick used to turn the headlights on and off.
9. Scroll through the service icons to make sure they're all orange. If you see another failed icon illuminated in red, follow Steps 3 though 9 until all service warnings have been reset.
