 goes off like clockwork as soon as I crest the hill
 and pull into a smaller side road (rpm decrease). It
 will buzz until I put automatic trans in nuetral and
 rev the engine.

 make a turn...it sometimes goes off.  My engine (one I
 bought from VW) has @ 75K on it.I recently installed a

Ben & Kevin,

I recently bought a 1990 Vanagon recently which needed a replacement engine.
After that was done I experienced the oilbuzzer deal. Exceed 2,000 RPM and
she buzzes. Spoke to Rich at my local VW shop Tassi's and gave me the
following advice.

Disconnect pressure sensor (the one at the oilpump out back) at connector on
top of engine. Ground the connector to the engine block. It the problem goes
away while it's grounded, the problem is the probably the sensor. If not,
it's the controller.

I never got a chance to ask what the "controller" is. Once the buzzing went
out with his test, I assumed it was the sensor. I replaced it. Problem is
gone.

Since Kevin has replaced his sensor, perhaps his problem is this printed
circuit board (aka controller) that Rich is talking about.
