Hi, I've been having problems with my 2008 A3 1.4 TFSI, mostly once it's warm, I get sudden engine knocking if I try to accelerate hard, as if there's a sudden loss of power or fuel for like 1/2 second. No DTC error codes. I was told it could be the mass air flow sensor needing cleaning or replacing, so I tried to take it out but I can't find the damn thing :O I located the MAP, where a friend wrongly told me the MAF was, but nothing else. Where is it?
not in here either
