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!
