2011 W204 C350 Radio/climate control module issues
My 2011 C350's radio, climate control, and window buttons lose power intermittently while driving. The radio screen will open/close (go on/off) repeatedly, while the climate control powers on/off repeatedly while driving. Sometimes they regain power, sometimes they don't. If the power stays off, I have to hit the dash to regain power. I went into the Engineering Menu and found the following codes:
DTCc168 Lost communication with EIS
DTCc146 Lost communication with CGW
I LOVE THIS CAR. PLEASE HELP!!!!!

EIS is the solderless ignition key module.
At this early stage you would do well to scan the whole chassis to see what every module is reporting.
