I went through a somewhat frustrating bout with that buzzer. I replaced the
higher pressure oil switch and the issue stopped.... Then it came back.
So far, it seems a section of the OEM brown wire from higher pressure oil
switch
was the culprit. I will be measuring engine oil pressure soon but the
buzzer issue ceased and hasn't come back
Of note, I did the Tencentlife "add a washer to compensate for worn oil
pressure relief spring" trick and changed to a different (proper AFAIK) oil
filter but those things did not fix the buzzer issue.
I can't speak with any authority on this but if my assessment was correct,
that corrosion in a 10" section of wire was the cause of
the issue, that dynamic oil pressure warning system "L" board must be quite
sensitive to (voltage?) variances.
