Nivau is no longer in a basic position.

Hello together, I was on Wednesday with my Diva at VW to make a check. After 1.5 hours I got a list of defects that should be made in the near future. As I ran to my vehicle, I noticed that the ass was pretty high. I ignored this first because I thought that this would level up again during the ride. Unfortunately this is not the case. After a few kilometers, I got in the display the error message “Level regulation workshop! … Ass still stays gaaaananz high up and the way it feels, there is no air in the front. So I am back to VW the next day and explained the problem to them. Now they said that some things had to be done to get the vehicle back to the standard. Today I got a call and VW said that they still haven’t found the mistake. Meanwhile he has been standing at VW since Thursday. It’s frustrating because before this “CHECK” everything had wonderful funk And all of a sudden, nothing should work anymore?… It seems to me that the vehicle no longer comes out of the jack mode. Maybe someone has ever had the problem? Because normally, he would have to deactivate from the jack mode after a certain time and spend himself in a basic position. But I don’t know if it’s just this mode. VW just meant that he doesn’t have the normal values anymore. But you can’t just re-establish the vehicle. Calibration and good is?…
