'87 5000CS Turb. AC compressor problem

[BrettD516@aol.com]

I have a 1987 5000CS Turbo whose A/C compressor has kicked the bucket.  While
it still works(barely), it is incredibly loud and the car shudders every time
it comes on.  I have removed the clutch relay, and I don't think I'll need
the A/C until late spring, but the mechanic told me that it will cost 600 for
the compressor(made by AC Delco) and he'll install it for 200 (including
freon or whatever they're using).  This is the third compressor that the car
has munched, the second because they didn't flush all the metal shavings from
the first one.  This one has lasted for about 3 years.  Now, the mech. said
that Delco guarantees the compressor for 6 months, Audi for about a year.  He
also said that this is a problem with this compressor, and that the new one
will last 3 years before it has to be replaced.  This is slightly rediculous
to pay 800 bucks every 3 years.  Can someone enlighten me to the
possibilities of get it replaced or some reimbursement?  Have other people
had this same problem, or is my mechanic BSing me?

PS:My audi starts great in the cold, but if it's warm and not run in a little
while, it takes 10-20 seconds to catch.  The same mechanic told us that it is
a problem with all 87 5000CS Turbos.  So did the guy at the parts desk at the
local dealership.  Do other people have the same problem?
Help!
