Question about 2004 Mercedes-Benz C230 Kompressor
The car knocks and diesels at a low rpm, i unplugged the mass air flow sensor and now it doesn't knock but of course the check engine light is on. does this mean i need a new mass air flow meter?
when diesels knock and diesel at low rpms it generally indicates a dribbling or leaking injector/s
have an accredited diesel repair shop check it out
If it has some miles on it and the injectors have never been done then the injectors are a fair bet

Testimonial: "the car is NOT a diesel. and like i said, when i unplug the mass air flow sensor, it stops knocking so it's not the injectors."
