Default Which Vaccum line is it?

I dropped my car off at the dealer this am for a CEL. Dealer called and said it was a Vaccum hose/line which needs to be replaced and wanted $270 to do it. Needless to say I will do it myself before paying $270, but I am not familiar with the vacuum lines. According to the dealer it is the hose on the back of the intake to the intake manifold housing? Does anyone know which hose they are talking about? Picture? Part No., etc.
Thanks.

Default Sounds like a Kombi valve hose, to the manifold.

Check the lines going from the little cylinder behind the engine to the intake manifold, then check the line that connects to the front of the manifold. Those are the only lines that I can think of there.

Default then you have 4 small diameter vacuum lines...(edited)

<center><img src="http://pictureposter.audiworld.com/143/vac-lines.jpg"></center><p>
one from 7(combi valve) to 23
one from 8 to the intake manifold
one from 27 to 23
one from where #24 is to 23

if the dealer said its at the back of the intake manfold then its either:

one from 7(combi valve) to 23
or what someone else mentioned, the "L" hose from #14 to the intake manifold

remove the engine cover (3 screws, use a coin) and poke around and look for broken stuff.

(fixed an error)
