Had this message come up on the dash .Car is Megane 2.0dci .Plugged my code reader in and it says open or short in Mass Air Flow (maf) Circuit.
Improper voltage at Mass air Flow (maf) sensor. Faulty Mass Air Flow (maf) sensor. Does this mean I need to replace the Mass air flow Meter?

Thanks Dan.

Obviously, it may not cure it - it could be a break in the loom for example - But replacing the sensor is the cheapest and easiest place to start.
