2.8L vacuum lines
1998 audi a4 2.8L quattro.
I think i have a vacuum leak. got one code for it. Besides, its time to change out the lines/hoses anyways. So ive been looking for a diagram that shows all the vacuum lines. Ive seen quite a few 1.8, but i havent been able to find 2.8L.
could someone please point me in the right direction?
thanks guys

Or just remove and replace one at a time. The routing is pretty easy. Which wires do you mean? Plug wires? Don't bother unless they're misfiring and known to be bad. On these cars the wires rarely fail. Mine are original at 204k miles and firing perfectly.

I am also getting vac codes. I replaced all the vacum lines. Now its throwing codes for EVAP, emmision control system, and vac lines. One guy I spoke to said it might be in the intake manifold or in the PCV line... I cant put this puppy through emmisions and Im kinda lost here, any help?

Are you sure that you got the vacuum hoses routed correctly? I got a CEL immediately after I replaced all my vacuum lines, and it turns out that I had routed a couple of them incorrectly into a Y connector. As soon as I carefully rerouted them, the CEL went away.
