    The struggle is real... the harder you try the more difficult it gets. You pretty much have to do yoga / meditate to become one with the combi valve mounting bolts! LOL

    Looking at an 05 A8, and it's throwing codes for 2ndary air injection for both banks. I This is extremely helpful, because the current owner is ignorant, and selling for an interesting price

    Amazingly chill explained! I have an quattro s advance 4.2l v8, not the actual s6 and I don't have these problems just yet, but I feel so relaxed knowing there's stuff like this where you can just get on it yourself. Mine's gotten now to 320.000 km's and I still drive it every day. It's my first car and I feel like I won a lottery xd

      N80 purge valve has nothing to do with secondary air injection. USA market didn’t have secondary air injection on 2.0t maybe the hybrid q5 got a Canada 2.0t hybrid that has secondary air injection. USA 2.0t just idles up for about 1 min after start to warm up catalysts faster for emissions
