JD 135c

Having a random issue with our 135c. The low oil light and warning buzzer keeps tripping. I can run for days and not have it come on, then sometimes i can only run from anyware from 5 min to 5 hours and it will come on. Sometimes it will not shut off and others it will shut off after a min or so.. The engine is running perfectly fine. Talked to the local dealer and they said they have never seen a pressure sensor go bad.

Is their a way to silence it from the cab?
