Need some help please. I plugged my A4 into VAGCOM today to check out some info I was told by the garage that serviced my car.
It came back with no faults (thank god!), but the MAF readings were changing wildly between 130mg/str to 320 mg/str.
Is this ok ? the Specified readings are supposed to be 170mg/str to 180mg/str.
I assuming the MAF sensor has gone wrong and needs to be replaced, but not being very knowledgable about cars I'm not sure .
Any help gratefully received
