How to Reset the Oil Light on a BMW 745i

1. Open the fuse panel cover in the driver's side footwell by pulling down on the cover with your fingers.
2. Locate the pinned connector in the fuse panel. It will be a large, circular port.
3. Plug the OBD reset tool plug into the large round pinned open port. BMW uses a special tool, called an OBD reset tool, to reset its service indicators. These tools must be purchased from BMW.
4. Turn the ignition to the "on" position and don't crank the engine.
5. Wait for the reset tool to clear all engine codes. It will then reset your oil light on the dash.
