Oil Pressure light minor issue

[Garageaholic]

The oil PRESSURE light is on (actually only flickers) only at idle, and only when the car is completely warm.

the second I either rev the engine or simply drive the car, the light goes away..

The oil pressure switch is new... but I recently had a coolant system bleeding problem and blazing hot coolant was spewing all over the switch... on more than 1 occasion. Could that be the problem?

I've heard of people who pressure wash their engine bay have oil pessure switch problems...

dry it out and clean off the connector

Hmmm,

Doesn't sound like a switch problem but an oil pressure problem.

What engine are you running? and what weight of oil?

I'm running the CHEAP 10W30 oil, only to flush the engine out. I am doing an oil change this weekend with a heavier weight.

I will also be replacing the switch and see if it goes away. I hear that the oil pumps are supposed to last forever on the M30 (latest generation).
