 the 30V V6 uses a timing chain?  Replacing a belt in my 100CSQ is
 trivial (lot's 'o room), replacing the belt in an A4 looks like a daunting
 task.  It would be nice if one didn't have to do it at all...

Try it on a V-8! Not too bad, really.  The V-8 has a serpentine cogged belt
that drives the two exhaust cam sprockets, each of which in turn drives (via
chain) the intake cams.  Does anyone know recommended service interval for
these?  I know the drive belt sugg replacement (which I just did last summer)
is now 60k miles instead of 90k miles.
