My i4 is 3 months old and my sunroof rattles when it’s closed? Anyone else with this problem?
UK owners of F series cars found that the use of wash and wax shampoos made their door and window seals creak. Only wash these cars with car shampoo (no wax). I certainly would NOT be putting any wax near any of those rubber seals. People go on about Gummipflege, but the MB Krytox is a far better product if somewhat expensive. Just lube those seals.
