Removing the dynamic oil pressure control board completely disables the oil pressure warning light unless you do some extra wiring. If you want to disable the >2,000 rpm light and buzzer simply connect the wire for that sensor to the chassis. That will change the warning operation back to the 85 and earlier replace engine light operation.

I suggest start preparation for removing the lower left push rod cover..
like start spraying penetrating oil on the exhaust flange bolts and nuts ..
so you can get that cover off,
since that is the first step to accessing the oil pressure sender under there..
which is where you'll tap into the engine for your OP gauge ..even if just for testing.
I think Van Cafe sells at kit for that,
so does TenCentLife on the samba ....fitting, a metal line, etc..
these days on any waterboxer engine I build, it's standard now to install this fitting and pipe, so my oil pressure switch or gauge sender, ( or both ) can be just forward of the left intake runners ..
near the t-stat housing.
on any high miles waterboxer engine ...this is the only way to really know what the OP is.
On a typical old engine ..I find, using 20W50 they run at 60 psi at tops ..like cold and say 2,500 rpm ..
and easily see only 6 psi at a hot idle.
But at least you have some 'intelligence' on the situation this way.
oh ..not really recommending this ( seriously ! ) , but ...the circuit that has the buzzer is installed inside the speedometer housing ( clever VW ! ) ....I'm not sure, but it might be possible to remove it and still have the oil warning light working ..
tho not sure at all about this and I don't recommend it.
check out Van Cafe's OP guage kit.. ..I think they have one.
