Udi Siag 0 Posted June 11, 2011 Report Share Posted June 11, 2011 What will a bad mass air flow sensor cause?i wanna know what problems can the bad MAF cause. Link to post Share on other sites
bungy 2 Posted June 11, 2011 Report Share Posted June 11, 2011 The maf includes a wire and a temp sensor. Current is adjusted to keep the temperature constant with varying air flow and this value is used in the ECU to adjust fueling. (I think that is a fair description)...

VR6Pete 1,455 Posted June 11, 2011 Report Share Posted June 11, 2011 If you suspect your MAF is shot, just unplug it. If it then runs like a bag of spanners then that would indicate it works ok, if your car is runnig rough already and when you unplug your MAF and you see no changes to idle then that indicates a faulty MAF.

Lukey. 381 Posted June 16, 2011 Report Share Posted June 16, 2011 the best way to tell is if your car is running like a bag of crap, unplug it and see if it gets worse, if it does then your maf has probaboy had it, shame a device doesnt exist to just check them, but there isnt.they are delicate little flowers and break if you look at them, im sure thats by design so you have to give VW another hundred quid! lol Link to post Share on other sites
