Years 1998-2006

Answer

If the on-board computer of your BMW 3 Series E46 no longer works, the ideal would be to reset it to the factory settings. The procedure should be described in the car's user and maintenance manual. If you can't do it or can't find it, try disconnecting the negative pole of the battery for a quarter of an hour. The system will reset completely and should return to the initial settings.
