Having problems with your 2003 BMW 5 Series ?
Does replacing the Battery in my 2003 BMW 530i require any special concern for the on board computer or sound system?
If the radio is security coded which is activated it will not work after the battery has been disconnected,it is much safer to connect another battery before disconnecting the original battery.....hope this helps.....cheers
