Jim-

I had the same happen to my Avant two years ago.  Turned out to be
the driveshaft seal - the drive shaft that goes back to the rear
diff,  You needed some special tools I did not have so I took
advantage of my extended warranty and still had to pay since the
dealer booked hours that the companay would not cover.  It was not a
two hour job since you have to remove the piece that holds the
seal-press it out then press in a new seal- it is all explained very
well in the factory manual.

I did not want to take it to a dealer but none of the local Audi
shops in the area had the tools or the inclination to do the work.
Sounds like they felt they really needed the tools to do the work
correctly.  So the bottom line is that I think it may be straight
forward to do but unless you have the tools it is not cost affective.

I wish I could tell you more since I am one to  do all the work
myself including my timing belt and RS2 conversion so I am somewhat
handy with tools.  It would be a job that a lift would really be an
advantage.  I know I will end up doing my clutch on jack stands but
since I had three weeks of warranty left I used it so I cannot give
you a blow by blow on how easy it really is.

Look through a repair manual and then call around for prices but the
dealer got $1600 for the job- sort like a clutch job but he did not
even drop the transmission.  I would think a local Audi guy if he has
the tools may do it for half.
