First check that the AC compressor belt hasn't snapped - it'll be down the
front of the engine.
Second engage the AC & then feel the AC lines - (usually aluminim looking
things routed around the side of the engine bay) one should go cold pretty
quickly & you should see condensation. If it does go cold then the AC is
working & try changing your cabin pollen filter - that worked for me on an
A4 a couple of months ago when we thought the AC had died.
If the line doesn't go cold then either the compressor/compressor clutch has
packed in or you have a big leak & have lost all your AC fluid (in which
case don't drive the thing too far). The fluid also acts as a lubricant &
without it the compressor will sieze if it hasn't already.

Re: '02 A6 AC stopped working
Iain,
If the AC system lost pressure, the low pressure switch would cut the power
to the magnetic clutch and the pulley would just freewheel - part of
recharging a system when it is under vacuum is bridging the low pressure
switch to get the compressor to run.
Jone,
Chances are, if you turn the system full cold and you don't hear the
occasional click of the clutch engaging on the compressor, and with the
engine off you can turn the compressor by hand (you can do it so long as the
clutch isn't welded to the pulley) will indicate that the AC has probably
lost enough pressure to activate the LP switch. If you can find the
location of the switch - it's a wired pressure transducer teed into an AC
line - and bypass it (for a short time to avoid burnout) to make the clutch
engage and run the system, then the system has lost some pressure.
