Mercedes Repair Questions? Ask a Mechanic for Answers ASAP
Hello,It would relly help to know what the fault codes were, which triggered the CEL. But from experience, the issue is often caused by failing mass airflow sensor.
I don't know the fault codes and unfortunately the garage erased the codes when they checked the EGR. I have been told that it could be the turbo actuator?
Your car might have a compressor, but not the turbo. Compressor engines have several flaps to control the airflow. They require cleaning and re-adaptation with the Star Diagnosis machine.
