Then looking at the 14 pin connector, it appeared that the metal pins were
a little “wide”, so I carefully bent them down so that it would make better
contact with the instrument cluster side. Seems to have worked. No more
buzzer. Now back to real problems.

Thanks all for the advice.

   Observed here often:  Idiot lights and buzzer warning  systems, they
seem to constitute a rather large percentage of problems reported or
inquired about here with the Vanagon....Oil buzzer, flickering oil light,
blinking coolant level sensor....these seem to be the biggest most frequent
offenders....
    The problem I have with these systems is when you DO see an indicated
problem, sent by one of these systems, it only means, to me, that you MAY
have problems with the system that the signal is supposed to be reporting
on, or you may have problems with the warning system itself....No way to
know until you take crap apart and diagnose the reason for the light or
buzzer.....Also, these idiot lights give no indication of the severity of a
problem they are supposed to indicate....Is is NO OIL!...or just that you
may need to up the viscosity or lower your operating temps?   Is it NO
Coolant left, or just some smut on the probes in the tank?
   Gauges....my answer.   You can at least get some information from
them....and when they don't work properly, the needle stays still, or it
jumps right to the top....you can see something is wrong with the gauge.
Do you suppose the car makers have made these systems in order to increase
repair revenue?   They must make a bunch of money hooking up vehicles to
read codes that are false......
