Not a diagram per se, but a close up photo (hope it helps):



Pretty much all those brittle looking fabric covered lines are vacuum hoses....plus those two in the lower left I replaced. It's the best photo I have off hand.

 

Thanks -- I replaced all the easy-to-access lines a little while back, but didn't get all of them. It looks like the line coming out of the vacuum reservoir under the coils is the culprit (I didn't even see that one previously).

A diagram would be useful, as there are a few somewhat hidden lines like the one near the driver's side headlight, and this time I aim to switch out anything I missed.

 

Can anyone send a better picture of a 2001 Audi A6 2.8 quattro im replacing yhr hoses but forgot exactly where they go.. Can someone send a picture like this below like one above picture so i know what hoses go where.. Please im stuck on side of road
