Hi, I have a 2016 c220 and the passenger door will not unlock, there’s as if the is no power to that door as power mirror will not work or the window can’t move seat as none of them buttons either work.
I have code read it and the is a lot of communication errors I have uploaded photos of codes.
I have also tried communicating with door but it will not.

thanks In advance.

I think given so many different systems it could be the SAM unit, Try checking the fuses/relays but otherwise have to start thinking about getting a Xentry diagnostics to diagnose a SAM issue.
