Wallace,
The thread was on June 14.
In addition, On Sunday June 21, I received this from Ned Ritchie:

A summary, based on listers comments...both 11s and 7.1 are green fluids,
and have the same Audi part number.  I think Pentosin 11s has a red cap and
7.1 has a green cap.  The two should not be mixed.  Your seals are already
shot on both pump and rack, from what you say.  You should replace both
ASAP.  The leaking fluid is making a royal mess under the hood, and I've
been told it can ruin sub-frame bushings and tranny/engine mounts.  I don't
know any surefire way to tell which fluid is in a car, because it may no
longer be whatever was installed at the factory.  I believe my 91 200Q had
11s originally, but the PO's mechanic replaced the rack and he told me he
switched to 7.1 at that time.

I should explain my reason for asking. After buying my 5kcstq, I headed
over to Carlsen Audi for a MFT from Linda, and I got some Pentosin while
I was there. At the time I wasn't aware of the different types, and I
figured she would've given me the right one anyway. But now I see that
my empty bottle of G 002 000 is marked "synthetic," and I just bought a
liter of non-Audi Pentosin 7.1 that is less viscous and quite green. I
had to put some of it in a few days ago. Prior to that, the system was
probably almost entirely synthetic, since I've used the Audi stuff since
changing the bomb and driving and leaking 2 bottles worth.

The pump and rack were already leaking, but I did just replace the bomb
and I hope not to damage it or anything else in the hydraulic path.
Should I go ahead and flush it (with what?) and fill with 7.1, or should
I just wait till I have to replace the rack and/or pump? Are the hoses
and everything else also damaged by the wrong fluid? TIA.
