as most of you know i have an a6 2.7t (similar to b5 s4) iv had an on going problem where my car takes longer to start first time of day and the revs are a bit jumpy, loss of power and boost cut.......... today i separated the pipe from the maf (MAF still plugged in to the loom) and the car cut out, so started it back up and it idled but problems still there, so i put it all back together but accidently left the pipe half way off, so it was sucking in air before and after the maf........ all problems gone...... very strange, so would you say the maf is faulty? getting no fault codes, apart from other boost related ones 17963 17965..... but hey that's another story.
