[s-cars] Please Help - Car bucking under WOT

[Greg Wolters]

Hi Scott,

On my 94 S4 it was the ribbed hose from the boost pipe into the inter cooler
underneath the engine, driver's side (the Michelin Man hose, I believe).  It
gets a lot of wear and tear down near the road and will often split in the
ribbed area... split wasn't obvious but the hose looked old and worn with some
oil that had dripped on it (or out of it!).  Same symptoms as you described...
replaced it with my Samco hose from the group purchase... problem solved!

When I pulled the codes I got 2413 "Mixture adjustment adaptation limit
exceeded".

Hope this helps... good luck!
