These MAFs are from my 2000 model M5 and have covered 20k miles, they were replaced under warranty with the thought they were faulty, but when the new MAFs were fitted the problem persisted, with the new diagnoses being Exhaust can sensor, when this was replaced evrything was 100%, to be sure the original MAFs were ok I fitted them to the car once more and again the car was 100%.
Offers?
