Cost, Source & Part number for '92 100CSQ Oxygen Sensor?

[Doug Rudoff <DougR@arkspace.com>]

I'm not sure yet if my loss of power is related to my oxygen sensors,
but it's one of the possibilities. The local dealer quoted $200 a piece
for them. Yikes! The father of a friend of mine runs a car shop in
another city and might be able get them for me wholesale (he doesn't
often work on Audis). Does anyone know the part number?

Or is there another source for the oxygen sensors? I'm guessing they're
made by Bosch, and maybe Audi marked ones aren't the best priced.

Thanks.
