hello, have the search already tried but found nothing. have bought the s430 before a week, have now found the following problem: if I have the outside mirror fold in, this is done on the side of the driver quite normal, however on the side of the driver it takes about twice as long as on the side of the driver. one hears on the driver side a quiet “tack-tack” as if the teeth would not grip correctly. does anyone know this problem? handles here the MB-europa-guarantee? car has circ a 88′ down and is completely stapled and was also bought at a MB branch.
