C250
Hi guys I’m new on the forum chat. I own a c250 w204 2015 coupe with 271evo engine on it 1.8T
My car lose power and I don’t have boost
I checked wastegate and looks is open but signal from Ecu is not closing it using the solenoid. I’ll check the power from the connector but I checked before and I it’s working
Looks more like the signal is not been sending from the ecu. I have a generic code P0068 last year I had it and I replaced with new map sensor and was fixed. Now 6 months later came back and loss all the power. Car is on stage two and only feel the power using the pedal commander. Also my rpm when down and back up when I press the gas pedal doing like 3k rpm. Just wondering if someone has this problem before. I’ll appreciate the help. ✊

The car is in limp mode, so its preventing the car from making boost, what error codes do you have in the ECU now?
