Thanks to those of you that responded.  I went home over lunch and found
the hose disconnected as ALL of your posts suggested.  It is truly nice
to have an "Audi been there/done that resource guide".  The good: I have
boost back as before.  The bad: I cannot tell my wife that the stock
turbocharger went bad and that I need to replace it with an RS2 TC from
Europe!
