hopefully you have a good relationship with your dealership. if you do and the problems persist BMW will buy you out of it and put you in something else. i know this from experience. i have been in the unfortunate position of having to have went through the process on 2 different cars. BMW wont make you go through the lemon law BS to make things right, they take care of their customers. the only problem is that its the dealership that gets it done.
