I bit the bullet and let BMW Sytners of Nottingham replace mine, but since they did it..the red light stays on when the roof is down and i have alot more wind noise coming through the door/roof seal when the roof is up!!! The work is garenteed for 2 years though so i think il have to return it at some point...wonder if id be given a car to trot about in while they have mine....every time i have asked they tell me they dont have one avaliable...................
