Posted before, but the archives being what they are...

Here is the official word from Audi on the 7.1 and 11S compatibility:

AUDI TSB reference Bulletins thru 1993 (issued Oct 1994)
Audi tech bulletin 48-89-T07, Nov '89 (EXACTLY QUOTED)
Hydraulic system fluid has been improved as of M.Y. 1990

New: Hydraulic Fluid, part number unchanged.
This fluid is more temperature resistant
Color: Olive

Old: Hydraulic Fluid, PN 002 000
Color: Green

The new hydraulic fluid can be identified by the RED cap on
the container

Note: New and old hydraulic fluid can be mixed if necessary"

Do NOT mix either 7.1 or 7.11 mineral oil in audi hydraulic
systems which  call for "Dexron Automatic Transmission Fluid". The ATF
hydraulic systems are  usually identified by the metal resevoir, the
mineral oil 7.1
and 7.11s  hydraulic systems are usually identified by the plastic
resevoir. ATF
application are usually found on the older 4000, Urq and pre
84 hydraulic  systems (USA). The 7.1 non synthetic mineral oil fluid is
usually found in  all 1984> 1989 audi 500/200 cars (USA) The new 7.11
fluid is found from the  factory in some M.Y. 1990 audis, and all 1991>
Given the better heat  resistant characteristics of the 7.11s (synthetic
mineral oil) fluid, it is  the preferred fluid for all audi applications
specifying G 00 2 000 mineral  oil hydraulic fluid.

If you have any questions regarding the application for your
specific car,  please consult either your owners manual, the label on
your resevoir, or your  audi dealer.
