I have a 2001.5 B5 S4. Not one day after I bought the car, a CEL appeared. I took it to the dealer and they diagnosed it as a O2 and potentially at CAT problem. I am working with the dealer that I bought from to get the replacement parts (free of charge).
Question I have is this. I just bought (in the mail as we speak) a V-Checker from ECS and the description stated that it can clear the fault codes.
Ok so this is what I want to do. My temp registration is up on November 1st. Arizona law dictates that I must emission tested the car before I can register it. With that said, if I clear the codes myself, and bring it to the emission testing, will their equipment pick up any faults? Do you think I will fail emissions?
Once I get the car registered, I will repair the car, as I was planning on replacing the O2 sensors and getting a full exhaust anyway.
