W204 Gesamttest NIO in instument cluster - rchotkan - 23-03-2022
Does someone know how to disable the message Gesamttest NIO on a Mercedes Benz W204?
It's displaying in the instrument cluster and we are not able to get out of this menu. Do I need to perform something or is there another method to get out.

You can start by diagnosing it, it has a problem and it will not just go away.
