Today I hooked up a boost gauge and found that I had a vacuum leak. I found the problem to be a cracked valve on the right rear side of the engine. Im not sure the name of it or the part number though??It is a tee with three vacuum hoses going to it.

Car is a 2001 Audi S4

 

if its just a tee then get a new tee from a parts store

 

why don't you provide a picture with a arrow pointing to the item, and maybe people can help you better.

 

This problem sounds very familiar...
I had a piece like this break on my car. Here is the picture i took.
Is that it? If so its like a $33.00 piece that is easy to change.
If not i dont know what to tell you besides take a picture.

 

Do you have a boost gauge hooked up? If so it's the FPR hose, get it fixed!

 

YEah, its the one in that picture. I went to audi today and the "parts specialist" had no clue as to what it was either. It should be in on Monday. THanks for the help guys
