I have started having a minor intermittent problem with the roof closing sequence on the car. Sometimes when I close the roof and the windows close one or both of them opens again by about 8 inches. (Yes I do wait for the light to come on and take my finger off of the button immediately.) This does not happen all of the time and sometimes it is just the driver's side or the passenger's side that is affected. The dealer took the car in for a couple of days and tried to 'adjust' the windows but the problem remains. Now they are contacting BMW for advice. Anyone else had this problem?
