Fellow vanagon types
I have never used the VDO gauge but I do get calls from people telling me
that they have low oil pressure after they install the VDO gauge. two things
I have come to understand about the VDO gauge are. #1 the switch for the
light is of higher value meaning it goes on at a higher idle pressure than
the stock .3 bar switch. #2 the gauge reads in 10 pds incroments and often
shows 0 pds at warm idle. I would recomend a screw in type gauge for testing
only like the snap on gauge I use to test oil pressure on the engine stand.
.3 bar is all you need at warm idle and as I said the VDO gauge will not
show that.

I would say if the light is out at idle and the buzzer goes off then the
dynamic warning system should be checked and you might install the .9 bar
switch under the Wpump
the other questions are does the lower fan speed work on the radiator and
does this van have a history of running hot
this does not sound like a oiling problem to me
