I have noticed a very weird issue lately. It all started with me noticing a red bar in the top of the head unit showing the text "Diagnostic startup is active".
Other than this everything seemed to work fine. Until I walked by my car and noticed that the head unit screen was turned on and music was playing.
This happens almost every time now. It does not happen instantly, turning off the car and then opening the car door shuts down the head unit display as it should.
I then lock the car and walk away. A while later (5-10 min) it will light up again by itself.
It doesn't matter if the car (C350e 2016) is plugged into the EV-charger or not, still happens even if it is unplugged.
What has happened here and how do I solve it?
