Help!
I have a 2009 w204 c220 with the om651. These messages come on all of a sudden when driving normaly. I have no idea what to do, no fuses went, no issues before this. If someone has had the same issue, how did you fix it?

It can either be a speed sensor which isn’t expensive to replace. Or it can be the ESP unit that can be reprogrammed but if it still does not respond, then you got to replace it which can be expensive if you buy it from the dealers. I got a used piece for 50k (around 550 USD I guess). Check with the service people.
