The Buzzer is actually controlled by the 1.8 bar switch, (the one located by
the oil pump.  Try replacing this with a 1.4 bar switch available through
VW.  It may solve the problem.  You should be able to hold better oil
pressure though.  The engine may be running too hot or you are not getting
coolant flow through the oil cooler.  Also, in warm weather, the Vanagon
should be running 20-50.
