How to Reset BMW Service Lights


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