Hello,
Are there any fault codes stored in the engine control unit after replacing the parts you have listed?
Is there a lack of power above 1200 rpm?
regards,
Stan

Hi stan
no I have not had fault went to limp mode ones and I took it to the mercedes dealer and he said to me that it's your exhaust back pressure sensor which is at the back of the egr valve
No there is no lag after 1200 revs
Expert:  Stan replied 1 year ago.
Such problem can occur if the mass airflow calibration has not been reset after sensor replacement. It has to be done with Star Diagnosis computer.
I suggest to ask from the dealer if such calibration printout can be sent to you to make sure it is done.
Regards,
Stan
