95 A6 Vacuum diagram needed
I just bought a 95 A6 FWD and am fixing some issues the geniuses before me caused and others they didn't fix right. I have a vacuum house near what I believe to be my blower motor that is just tossed in the compartment with a screw inserted into the end. Does anyone know where this goes or where I can find a vacuum hose diagram.

That vacuum hose goes exactly on the other side of the blower, connecting to some type of valve/pump as you can see in the pic:

And here's a diagram, if you don;t already have one under your hood:

You're welcome.

That could be a problem. I just replaced one of the heater hoses and that diaphragm looking part is not there. Looks like the problem goes even deeper then I thought.

Is raining right now, but when I have a chance (tomorrow probably) I'll check and see if that diaphragm has a part number on it.
P.S. I looked thoroughly through the Bently manual and I cannot find anything related to this particular part.

To bring life into a dead horse. I have figured out almost all of the vacuum issues the only one that remains is that i disconnected the vacuum hose that goes to the one way check valve and dont remember where it goes on the motor. 
According to AllData it connects to the engine vacuum supply. Every vacuum diagram that i have found does not show where this hose goes. When I originally removed it, it was attached somewhere near the EGR in the diagram that chefro posted.

Look right where the fuel regulator connects to the manifold. Should be a tee there. If not there, then under the MAF where's there a mess of them comming together.
