Sounds like a buzzing sound coming from oil pressure gauge for a few seconds when I turn the car off. Anyone out there have this problem ? Is it the oil pressure gauge, if so what's causing it to make the noise ?

Since the oil pressure gauge is a mechanical one and it's connected to the engine with a plastic tube most likely. Not sure how the engine vibration could be transferred through that. Maybe the tubing or some wiring harness is resting against something and causing the buzzing noise.
