I am receiving the same two trouble codes, p1128, and p1130. They state that my fuel system is running lean on both banks and i am getting quite a power loss. Is it just my oxygen sensor's or is it a maf sensor... would like another opinion before I start throwing parts at it. 2000 s4 2.7l tt

I hate giving my advice as with these cars alot of times the obvious isn't the problem as I have come to find out. However, I had the same codes on my 2000 s4 and it did end up being the MAF sensor. Hated to spend that much money when I wasn't sure but I guess I lucked out this time. lol Hope this helps...

MAF is more likely than 02s
