Recently i have done a star diagnostic for my w208 230 kompressor. I request any expert who is willing to help me sorting these issues. I am newbie and my wrenching skills are not great .... Thanks in advance.
the f could just be a power fail at some point, (flat battery etc?) the F are current so need to be looked at. Instead of doing a quick test and expecting answers, try to do an indepth diag on each of the control units and look at what error was flagged.
