I have been having some issues with my car, i fitted new coils, plugs, full coil loom, injector seats, inlet gaskets. Still no better, i had done some logs with VCDS and MAF readings seemed all good. I then read on a post that the MAF logs dont tell the full story. The MAF that was on the car was a genuine recon approx 2 years ago so sort of dismissed it. One day i just thought id unplug the MAF see what happens, car drove much smoother. Got on the net straight away and got another genuine MAF ordered. Fitted it and staight away i realised my old MAF was probs OK. Ive unplugged the new MAF and its running smoother again??? Could this be because there ia unmetered air getting in? And with it unplugged its going of the base MAF tables?
