What about leaving them open then? A little loss in drag and fuel efficiency vs. an expensive repair.So far no codes, but I believe its due to the Motor for the cooling-air flaps not working.
I found the flaps in the open position and I can manual move them. I check this on another Macan and there won't move. I guess the gear is stripped.
I ask the question, how difficult it is to change the motor, in another post.
