I *think* there is a factory update to this hose/system.

Scott Mockry's site says:

"Vacuum Leaks-Breather Hoses!

     You need to make sure your engine’s various breather/vacuum hoses and
turbo intake and pressure hoses are in good shape.
     Leaks anywhere in these hoses can cause lean or rich running and poor
starting. " ... "The large breather hose coming from the side of the engine
that is routed around the back of the engine typically gets rotten and mushy
on the inside part of the hose facing the engine block. Often times the hose
can collapse on itself or will split open on the back side. This hose does
not have hard vacuum applied inside like the 10V Audi Turbo MC engine but
leaks could allow un-metered air into the engine. The 20V breather hose has
the Audi part number 034-103-221AF"
