MAF sensor problem w204 320CDI

[Neil Bainbridge]

Hi I would if someone has ever had this problem, I have an engine check light on and a P0101 code "Mass or volume air flow A circuit range / Performance" I have changed both MAF sensor in the Air fliter to turbo inlet pipe. I can clear the fault but next day the light is back on with the same fault code.

Help!!!!

Did you also replace the orange seals on the inlet pipe at the turbo end? Air leaks can cause this code as well. Check there are no cracks in the pipe.

Sounds like an air Leak to me.

Maybe find someone who has star diagnosis close to you who can check the fault codes and carry out accurate diagnosis. You are just guessing at present and your code reader isn’t helping.
