Ok, that's from the '83 diesel diagram, 97.43, which I missed.  Appears
identical to the '83-4 waterboxer.  However, if there is in fact no "cool
low lvl wrng sw" (IOW those two stainless pins sticking into the expansion
tank) then the line coming from pin S of the control unit has to be tied to
some fixed voltage or it will permanently  sound the alarm.  So something
is missing from some diagram somewhere -- or else they just didn't install
the control unit, which makes plenty sense since I'm sure even VW paid a
deutschmark or two for it.

If there *is* a sensor in the expansion tank, short across the plug and/or
ground the wire that isn't brown.  If the blinking stops, bad ground or
dirty sender pins.
