Hello, unfortunately I used the jack wrongly and placed it further in front. Now both sleepers are pressed left and right. On the driver’s side even pushed so far up that the door hit the bottom of the sleeper. This was corrected in the meantime with the hammer so that the door no longer roams. Now it was so that I once did not get a TÜV with it. The follow-up then went through without problems and the last TÜV even on the first time without Now the question, because on demand one or the other thought that the complete threshold would have to be changed. Is this really absolutely necessary? From an optical point of view it doesn’t matter to me and the door does not roam as far as possible. Is it absolutely necessary from a safety technical point of view or for other reasons? I ask for feedback!
