PS fluid G004000M2

[John Larson]

You asked:  "I just purchased a liter of Power steering fluid. On the 
invoice it says it

replaces G002000. I bought it at a VW dealer and the container has the Audi
and VW logo on the plastic container.

The question is this new product backward compatible so I can flush and
replace the old fluid in my 1990 80, non-Q? The product is made in Germany.
Range of operation -40C (-40F) to +130C (+286F)."

1 Litre isn't gonna even come close to flushing and refilling the system.
Probably takes at least 3.  John
