Have a 03 2.7T and no where to discuss mods. I saw a post re: Jack Mode, didnt know of such, where is this located? Or would this just be the lowest setting?

FYI: Had a set of wranglers last close to 30K, not bad at all.

 

In an 04, you hold the up and down buttons for a few seconds, at the same time. I wouldn't have known about it either, except the dealer made a point that it is important, during the orientation session, at delivery.

 

For engine issues, go to the S4 forum. We (B5 S4's) share the same engine.

 

go to audiworld.com (allroad, B5 S4 or C5 A6 forums). Good luck!
