Hi mike,
My understanding is that the Hitachi MAF speaks a different language than the Bosch - so its a software change in the ECU.

So your S4 has 120k on it? cool - original turbos?

I am trying to decide what to do with mine. I have 85k, and my extended waranty ends next year when I hit 100k. I love the car...But I am not sure I trust it without the warranty. 

The A3 is a pretty sweet car too - and next year the AWD version will be available. Maybe ill trade in.

Anyone hear word on an S3 coming to the US?
