Apparent false reading of oil pressure sender - 91 200 TQ 20V

[Bill Batty]

I have a most frustrating problem! The red dripping oil can warning light started to show itself on an irregular basis even though the standard O K showed upon starting my 1991 200 20V. My mechanic replaced two different oil pressure sending units. The indicator light still goes on even though I still get the O K upon starting and my oil pressure gauge goes to within a hair of +5, the max (which was where it was when the problem started). Recently I had my front UFO brakes replaced and my rear brakes checked and the other day my brake pad warning light went on as did my "out of gasoline" warning light just after I filled up my gas tank.

I do not know how to locate the problem.

Replacing the "Display unit for the on board computer and check package", "circuit board" and/or "the computer" is VERY EXPENSIVE. Maybe I could get a used instrument cluster. However there could be a problem elsewhere causing false readings.
