rumor is that the euro audis [not m/a yet] are using upstream injectors
[intake] to wash the backs of the valves to prevent / minimize carbon
buildup. read any rs4 forum about it, the pictures are a horrorshow. guys
rolling in with the ports 50% clogged and putting down 200hp. agreed that
it's a 40k service check / job. i think most shops are doing it for a few
100$. it's not a nightmare, just another component to the vag ownership
'character'. trade your cam follower checks / replacements with decarbon
