Oh, not only do I have a CEL.... its FLASHING. And I gotta say, thats a first for me, saw that and instantly backed it down the driveway to park it. Anything??

 

well if its missfiring, that sounds like a bad coilpacks.....common problem/easy fix... i would install some new coilpacks (if u ar eat 93k and havent replaced them, u r overdue anyway...) and go from there...

as far as the clicking on the passenger side, its common as well... my car has always done it...

 

Bear with me, a little learning experience on my part.
-What isthe easiest route to either of the compressor wheels, and am Igoing in from the top or bottom?
-As far as the coilpacks going bad, how many do I have, can I check them to see which one is bad/ or just replace all of them? Not very educated on the subject of coilpacks and there purpose... at least now I'll have something to look into during my stats class.... Finally, I'll get to learn something instead of sleeping through it, yay.

 

sounds like ignition coils same problem I have. mine went out at 64k, so like papachristou says you are way over due. I bought mines at http://ecstuning.com/ they just came in today matter of fact

 

Whoa... an 04' with 93k on it??? Are you the original owner, or did you buy it used? If you're the 2nd owner & bought the car at an Audi dealership, it will have a CPO warranty with it. The CPO warranty will cover the turbo, but not sure about coilpacks.

 

Whoa before you start wasting time and start pulling of the TIP and all the other b.s. to get to it, vag the car or if you dont have a vag get it scanned at autozone for free. Get the codes find out what they are saying and go from there. It could be something as simple as a coilpack whic would only take 5 minutes to replace.
