Following message showed up on my dash this morning: Malfunction Serv.Req. No warning lights just the message. Looking through the car's manual it says that there's a malfunction in the coolant compressor or in the heating/coolant circuit. My heating and air-con work fine. Anyone else experienced this?

Sorry I cannot help. I have had a "malfunction" displayed on my 2014 lately when I plug into a level 2 commercial charge station. I walk away and when I return usually in an hour is has charged and the message is gone; but, then the car won't start and displays
"drive system engine off". I then have to wait 20 to 40 minutes before the car will start. I will most likely bring it in to my MB dealer soon but I don't hold out much hope they will know what is wrong.
