Need Help locating vacuum hose for my 2010 audi a4 2.0t premium.

 

Not sure what you're asking? However, typical vacuum hoses are small plastic lines (about 3-5mm in diameter) generally connected with short rubber/silicone hoses to the items needing vacuum. They usually originate from the intake manifold around the throttle body. Surprisingly there aren't that many on engines these days (not like it was in the 70's,80's, and 90's) now that a lot of components are now electronic.
