I have a 2003 530 i and my check license plate light keeps coming on . When I have the head lights on my license plate lights are on , when I have the head lights off the licence plate lights are off . Any one ever have this problem ? The lighting system works fine (parking marker lights head lights and license plate lights both when their on and off . It's when I'm driving I get warning on instrument panel "check your license plate light " and their seems to be no problem with I cant understand why I keep geting this warning ?
