[s-cars] Pentosin white or green bottle for my power steeringfluid.

[Robert Rossato]

VW/Audi state that you can mix the newer synthetic fluid (11S) with the older mineral fluid (7.1S) system, but not the other way around.  So if it's 11S you're okay.  I would imagine the issue is one of compatibility with the o-seals in the system, so you may not notice anything in the short term, but may end up with leaks all over the place down the road.  So, if you have a can of the 7.1S, I wouldn't use it.
