I've spoken a few times the other day, if anyone cares, it was of course the Ot-Geber! I also got Tüv, and so that this runs smoothly, before in the instrument cluster the airbag light is deactivated, the Tüv man did not notice it :-)
So and now to my contribution, as if there had not already been enough problems at the same time, I still have this screeching in P and N. It finally turned out to be a hanging Zünschloss, the "screeting" of course only appeared in P and N, because the starter is "free" and so it went along! But now that I already have the 2nd Zünschloss in it (was replaced by VAG a few years ago), I have found a different solution than turning the key back by hand.
So, I just removed the cigarette lighter and put a start button in this place. The fence was connected to terminal 15 (duration plus), terminal 50 (starter) was tweaked and is now connected to the start button on the other side. I'm going to put on some photos, I think it looks quite passable, I'm also glad I didn't have to drill a new hole somewhere in the center console. The button is a little "grey" but it can withstand 50 A load. The only thing to find out is whether it is bearable in the long run to have such a bright red light in the field of view...especially at night
