I would't wonder if they fiddled about with the amount of seal swelling
agents and the like in the factory oil, so that when using other oil, the
seal swelling stuff leaches out of the seals, and it leaks. I know of a few
VW's that use of ATF in the power steering coincided with rack leakage.  I
have used the lucas oil power steering universal stop leak oil additive good
for leaking racks, and it did stop the power steering leak at the rack, and
prevent further wallet leakage.
I use VW stuff in the vw's.
I run plain jane synthetic atf in my race car power steering. It's just
fine, doesn't foam, or break down. For my uses, the Amsoil stuff is kind of
John Deere used to really push that universal tractor oil years ago, where
one oil was for diff, engine, hydraulic, steering, tight boots, runny noses,
etc, but it cost them too  many motor rebuilds. Anything that ran a
detergent oil just coughed and died once put on a diet of universal oil.
Not sure why, but never had opportunity to tear one down to see either.
