Hello, now I’m probably also affected by it….I noticed in the last few days that the driving quality is no longer as I know it. Pretty hard.Almost as if I have operated the chassis switch on the armature so hard on sport. I also noticed today that when pulling off the lock, at least at the rear left the vehicle is slightly lowered. Shock absorber,Airmatic, what can this be now? The Airmatic itself can still operate this lift and lower depending on the choice. uch in a normal period of time. Many thanks to all already. Bernd
