[BiturboS4] S4 MAF's

I just replaced the MAF in my 2000 A6 2.7T.  It was replaced under warranty so it was replaced with the OEM unit.  The car only had 23,600 miles on it when the CEL came on.  The codes indicated system too lean... I think it was P1128 and P1130 if I remember correctly.  A MAF replacement solved it...

Hi all,
    Its looking like I need to replace the MAF on my 2000 S4.  From what
I've read it seems that the MAF's used in the 2000's are fairly
unreliable and that they use different ones on the newer S4's. I've also
seen that some tuners sell RS4 MAF's as well(usually with the RS4
turbos). I'm wondering if anyone has replaced the MAF in their 2000 S4
with anything but the stock part and how well that worked, or if it even
feasible without reprogramming the ECU. I'd also like to hear from
anyone that has had a MAF fail in a 00 and how many miles they have got
out of it. Mines at 53k and seems to be going slowly but surely.
