I just Got the Hansshow premium audio upgrade harness installed in my M3 2020 SR+. I didn’t do this myself, but I got a 3rd party workshop to do it for me.
When I got the car back, I noticed that I persistently got the error “eCall emergency call system needs service”. The error won’t go away after 4 days, although I have tried soft reset (wheel buttons), turning the car off on the LCD, letting it sleep for hours, etc. I also checked the passenger footwell trim if any cables had come loose, but nothing here.
A far as I know the harness doesn’t have anything to do with the eCall system, so either the workshop must have unplugged something by mistake, or there is a hardware error which happened to pop up the same day.
The car will go back to the workshop, that’s for sure, but I also wanted to make sure that this is not something i can fix myself.do anyone know of any fix or if it has to do with the harness upgrade itself?
