I have a 2000 S4 which has that engine.  My 
experience has been mixed- it is a wonderful car and
motor, a joy to drive, perhaps the best put together
car I've been in.  But I've had a few warranty service
issues- failed water pump at 30K, failed MAF at 45K,
and a few more minor issues.  Now, the water pump is
again making noises.  Due for 60K timing belt service
anyhow (any leads on south bay shops for this work?
It's ski season, I need the car and don't have the
time to do it myself).
I've replaced the BPVs and in the process noticed
some badly degraded vacuum lines, which I replaced
myself.  The headlight washer pump exploded so after 
replacement under warranty I disconnected it to avoid 
a repeat.  What else...
My advice- buy one that has never been chipped or
modded, and has been regularly maintained, preferably
by a dealer.  Get familiar with the motor and the
things that need monitoring (pressure leaks, timing
belt 60K replacement, hydraulic leaks,etc. etc.).  It 
is not really much different than older I5 turbo 
motors from that standpoint.  Ti's link for the 
biturbo list is good, also spend some time browsing 
audiworld.  With some careful shopping and attentive 
ownership, it can be a great car.
Oh, BTW I have felt no need to do any mods to my S4,
I think the stock power is just great as-is.  The A6
is a bit heavier though, and I agree with Ti that
a properly driven chipped car can be quite reliable.
