S4 (B6 & B7 Platforms) DiscussionDiscussion forum for the B6 Audi S4 produced from 2003-2005 And B7 Audi S4 produced from 2005 -2008
Is there an engine component diagram that shows the vacuum lines. I know the lines to the fuel pressure regulator can crack at the T connection, as well as some braided vac lines which can deteriorate can be the culprits. I am trying to inspect them visually to see if I can find anything, but am new to this vehicle. Something to help me identify them woud be great.
Does anyone have a picture of the Vacuum diagram in the engine bay?
