I will get a pic up ( as soon as the damn digi camera arrives :rant: ) but for now words will have to suffice. On the lower intake manifold on the s5 engine, they are 4-5 vacuum lines, one goes from one of the secondary fuel injector holes to the other and then out to who knows where. what do they do and do i need them? same with the one at the bottom of the intake manifold. It goes, dunno where...

Are they on the firewall side of the intake manifold? I think one goes to the EGR, 2 or 3 (I think 3) go to the ACV, and on an S4 one goes to the twin scroll.

lower intake manifold, not the upper.

That's what I'm talking about. It might be different though because I'm going off of an S4.

yeah s5 parts shouldnt have any egr parts.
