which audis use Pentosin?

[Andrei Kogan <abk@phy.duke.edu>]

Sorry for a dumb question, 
Do all Audis use pentosin in their hydraulic systems, or only type 44 ?
(5k,100,200). What about 80/90? 
Also, Which ones have the bomb? I understand that all turbo cars do. Is
that correct? What about the others?

I am curious because several people mentioned to  me  the weakness of the
hydraulic system  in  a 5000t as a reason to avoid buying this car with
high miles. Assuming this is true, and the hydraulics in 5kt is more likely
to fail then say in a 4k: do you think this is simply because people mix in
an ordinary power steering fluid instead of Pentosin?
