Re: S4 vacuum hoses

["Mike Miller" <MikeMilr@email.msn.com>]

If you are refering to the crimp connector on the turbo bypass valve, you
can just re-use the old one. I ran for a while with the hose just stuck on
there with no crimp at all and it worked fine. 
That hose you are talikng about is about $22 a meter at the dealer as I
recall. Check the hose from the intake manifold to the turbo bypass valve.
It gets brittle and can actually be burned thru under the heat shield. Also
check where it comes out of the IM  - it can be crimped where it crosses
the bracket on the back of the IM - if this hose is not fully functional,
the turbo bypass will dump boost at the wrong time. 
It sounds like you are seeing low boost. Email me privately if this is so
and I will send you all my tips on low boost problems on that engine. I
have BTDT !!
