Hi there, I am new to the forum and came here to ask fellow owners if anyone has had this problem before. I can take the key out of my 2002 316i, and still play the radio and operate the windows. The battery never runs down as I switch these off. My dealer says he has never come across the problem, and if I bring it in for an hour, he will charge me about a ton, but doesn't guarantee he will find the problem. Bit of a liberty really. Any help would be much appreciated, as I have not found anyone who has come across this problem before. The strange thing is that it doesn't seem to do any harm to the battery, but the problem still nags in the back of my mind. Many thanks for reading this, and all help will be gratefully recieved.
