Hi, I’ve got a 2013 Mercedes c350, when I bought it was remapped. The problem I have is that when I go on motorway drives after about 30 mins it goes into a sort of limp mode, but no engine lights come up, i feel as though it has cut the turbo out, i can still run the car at 70mph, once I get home and then the car off and on after a few minutes it’s working like normal again. I took it to a Mercedes specialist who recommended that I put the latest Mercedes ECU software. Did that and still had the same issue. Then he ran it on the STAR machine and said he was getting 0 reading on the dpf sensor so he suggested to change the sensor and wiring down there. Did that and still had the same issue. I don’t know where to go from here and without no engine management light he can’t pick up anything on his STAR machine. I was thinking if it’s something to do with the dpf regen, maybe it’s clogged up? Maybe a carbon clean could help, but not sure if I’m just wasting my money. I’ve noticed it occurs quicker when the car is hot, i.e on sunny days. Please can any give me advice on what to do or what you think to could be?
