I'm a bit skeptical about their diagnosis... just seems a bit too easy.  If
you can't afford to have anyone work on it, you're kind of stuck doing it
yourself.  Shouldn't be too hard to get apart.  Getting it back together
without any leaks might be a bit more difficult.  However, if you do manage
to get it back together you could get it to a muffler shop and have them fix
any leaks that might be there.  

Even with one cat totally plugged I'd expect you'd notice more than just a
check engine light.  You might get it back from Audi and go to an
independent shop for a 2nd opinion.  If you can get it back home you might
have a better chance finding a mechanic that would work with you on the

However, there are many other things that can throw the check engine light.
I wonder if the dealer even ran the codes.  Could just be a tired oxygen
sensor or some bad vacuum lines or even a loose gas cap.

How was the car running when all this went down?
