Hello everyone,
Okay, there's an update. Yesterday, I received information that the display is now suddenly showing the correct values. It's now counting down from 30,000 km and 730 days. Nothing further has been done to the vehicle since I took the
Screenshot of the control unit. It has been driven approximately 800 km since then. Apparently, the control unit needs a considerable amount of time/distance to adapt to new values. It's strange that it takes so long. But, well, there's probably nothing we can do about it, and now everything is back to normal, and the display is showing the correct values.
Greetings.
