I can also relate, my 06 X5 was acting up and the car only had 5000 km on it. The 4X4 light, brake light (!) and the DSC button was on i couldnt turn it off. Also my passanger seatbelt occasionaly turns on even when someone is sitting there. I had taken the car to BMW of Mississauga for service since its under warrenty but im to pleased with the sauga dealerships service dept. I am just about ready to get my two subs installed and im very skeptical about letting best buy or future shop install the subs becasue if anything goes wrong with the electrical system i know exactly who bmw is going to blame. maybe i show let bmw install the subs and amp.
