Hello everyone , I have a strange problem with my interior lights , the trunk light , the glove box light , the reading lights and the sun-visors lights don't work properly . They come on and stay on only for a second or two and shut down after that . Also if i lock / unlock the car the trunk light goes on and off in the same manner. Last year my car was at bmw dealer for a MPM and CCC replace after having water in the trunk - flooding the MPM and burning out the CCC as well . After getting the car back I ve noticed the problem . Can this be some bad codding by the dealer or just coincidence ? Thanks for your replies .
