Gary: This diagram shows the PNs for the hoses (Items 2 and 3):

The feed 4A0117125A and return 4A0117123A hoses are exclusive to the UrS4/S6 AAN 

They are no longer in the NAmerican Dealer Parts system (you might have guessed that). 

They are still in the Audi Tradition system (but expensive and they don't ship to the US at the moment)

The only important parts are the ends (their shape and size) and threads on the nuts. On that basis, it should be possible to get someone who works with cars, 
not tractors to cut off the hard pipes near the crimped fitting and install an appropriate hose, perhaps after treating the cut end of the pipe to a bead roll so the hose 
will be encouraged to stay in place with a clamp. Probably high temp hydraulic hose of the correct inner diameter would work.
