I think my cats are failing, I got the CEL saying the O2 things were reading 'above normal' emissions tolerances. I asked the Audi reps and they said it'll be about 2 grand to have them replaced. I don't have that kind of money for a few months and need a bandaid fix.

So, How far up do I shim them to make it go away?

 

WTF!?!?! wow...2k for a cat fix? damn. i say test pipe.....do this. http://www.audiworld.com/tech/eng53.shtml
then clear the code. and WHAM! you got power and no cel, not to mention it will cost alot less than 2k...jesus.

 

Thanks a lot, just what I was looking for!
