Resetting BMW service lights should be done after the intended service has been completed. On most BMW models, this is a simple procedure. The service lights are reset by using a service light reset tool available from BMW. The tool is connected to to the diagnostic connector, located on the fuse panel in the passenger cabin. BMWs made before 1988 used a 15-pin connector. BMWs after 1987 used a 20-pin connector. Both types of connectors are reset the same way.

- Moderately Easy
Remove the fuse panel cover and locate the 15-pin or 20-pin diagnostic connector.
Plug the reset tool into the connector input.
Turn the BMW ignition to the "II" position, but do not crank the engine.
Wait 15 seconds until all of the service lights have been reset. The indicator light on the tool should stop blinking at this point.
