I have a 5 series wagon (2007 530xi). Tried to open pano sunroof yesterday, but wouldn't open. Made no sound, as if if no juice. It would tilt to vent and close, but wouldn't open. The movement was smooth without rattle or jerk. To add insult to injury, now the vent won't close.
So now I have both front and back panels stuck in the vent (tilted up). The roof wont open and the cover panel is in close position.
I've tried reinitialization. It will only go through the first step, where it extends tilt and back. But it won't go through the full motion of opening and close.
So how to get both panels to close? How to fix?
