It's got an R ecu in it...not totally sure if that's different from a T5. And yes, definitely could use a little tlc! Glad it went to someone who will enjoy it, because I never did, haha!

Awesome car. Love those! My mother has a C4 A6 Avant with the 2.8. The 4.2 definitely seems like a lot more fun, haha!

Snow tires are your answer. My AWD V70 does that same tail-out thing on all-seasons.

Ok, put on a brand new ignition coil today, and it still does it. So I think it's fuel related. Still no CEL.

I did notice that there is an odor of gas around the injector rail, and that some of the injector o-rings seem to be seeping a very small amount of fuel. Could injector o-rings be the culprit? The car seems to run well 95% of the time, it just seems to have a little less power than it should. WHen it stumbles, it acts like it's bogging down, and if you nail the gas, it usually picks up and goes. Then it runs fine again. Weird.

Any more input? Please?

I also just had a thought that it could be the fuel filter or fuel pump as well....

Although the ignition coil does look quite worn. I should probably try that before a new cat.
