[urq] Upper Wastegate Hose on '83 Ur Quattro

[Martin Pajak]

Steve,

I didn't disagree on the WX... just completing the story by stating what the
Euro WR cars have.
Don't want any Euro listers yanking out their hoses just because...

Cheers
Martin

... I don't see any way that it would make any more sense ... that port is
documented as a vent on the WX ... it doesn't need to be connected to
anything ... in fact if you started drawing a vacuum there you would be
working against the WG spring and actually causing the WG to open sooner.
Admittedly there isn't much of a vacuum on the back side of the airflow
sensor plate.  Its been a while since I've looked at the engine in my car,
but I know that the line coming off the top of the igloo on the WX is
definitely connected elsewhere ...
