I have a 1988 VW Cab. Convert. It has an idiot light "on" that has an oilcan with it. It also buzzes when the car is started a few moments.
Can you tell me what to do to shut it off?
Do you
have the same problem?

With engine off pull oil dipstick and wipe off end with rag. Notice level indications on tip. Replace dipstick and withdraw again. Read oil level. If no oil is showing on stick. Add oil a quart at a time until it does. If oil is showing, check oil sender to see if wiring has fallen off. If wiring is ok, the sender may be bad and need replacing.

My car has been modified. With a different throttle body. It has a different dipstick as well. Do you think that may have some bearing as to why it buzzes? Just thought of that.

No I dont think that has any efect. Here is another thought about the problem.
To rule-out electrical problems with the "warning circuit board" in the dash, attach the
oil pressure sensor wire directly to a clean engine ground. If the light & buzzer still
comes on, then the problem is with the board (common) or wiring that goes from the switch to the board.
Also does your car have an actual oil pressure gauge apart form the idiot light?
Vw's have excellent oil pumps with lots of pressure. However since your car was built they have made improvements and your oil pump can be upgraded also if necessary. You can take an 'actual' pressure test from the removed sender hole with a gauge.
Another question is what viscosity oil are you using? And I use lucas oil stabilizer in all my vehicles to prolong bearing life. It adds a little 'spiderweb stringiness' to oil so it sticks to engine parts. Stays in bearings after engine is setting overnight/longer. Also boosts oil pressure slightly. Have fun!

Yes it has a separate oil pressure gauge. If it has a separate gauge. Is the warning light only for oil level or is it also warning of oil pressure? Using a synthetic 10/30 Mobile one

If you got a gauge you got 2 oil senders. The gauge 1 is larger and fatter. You can look up pics on net.
