I'm looking to replace that "L" shaped vacuum hose. Anyone know what it's called or the P/N for it?

 

FYI: 2004 a4 3.0L

That's near back of the engine underneath the plastic cover that has the four ring emblem on it.

 

I believe that the blue thing is a vacuum check valve. I'm pretty sure that the hose itself is nothing terribly special. any generic vacuum line should do.

 

That's what I thought too. Mine had a tear on the side of the tube leaking vacuum. When I took it off, I noticed that it was different sizes on each end. The part that's visible in the picture was smaller than the part attached to the engine.

I didn't see any PN on the actual tube so I was wondering if anyone had a diagram of the section broken down with part name and number.

might try to find it on here. I dont have a good diagram of the 3.0 system.

 

Thanks for the link. Can't seem to find it though...
