I mean something over a year now, and get angry about the tailgate, which occasionally on our good old East German streets quite poltert, clapping or as one might call it. Had it once in the WS had had it straightened (tightened, tightened up), then it went again for a while. But now I have the feeling, the two sliding doors connect to the tailgate, and make div. noises. Who knows that too? My problem with the ZV has after the 5th or 6th W the “only” the contacts of the doors have placed a little higher, and since then funzt ́s!!
