Hi I have a 220 sedan 2012 and the engine warning light came on and the car has lost most of its power. I connected a bosch code reader and got these error codes: P029900 (Turbo pressure 1 to low) and P024872 (low pressure turbo exit 2, component does not close) and P068501 (relay clamp 87 electric error)
Has anyone experienced these problems and know what I should do?

 

Reads like a possible failure of the wastegate solenoid. If it is stuck open, then the turbo will not build boost. In my experience (not with merc) a solenoid is fairly cheap.

 

@erling66 Did you track down the problem? If so, can you share what it was?

 

Hi erling66, were you able to track down the problem? If yes, what was your solution?
