False Oil Warning Light?
 

Periodically the oil warning light comes on while driving our 1993, 190E, 2.3. However, the oil pressure needle gauge shows excellent oil pressure. I suspect a possible short somewhere between the sending unit and the warning light.

Can anyone give me advise on what the problem might be? Problem could also be with the sending unit. But I cannot find it. Can someone tell me where to look for it?

OIL warning light comes on when the engine is approx 3/4 Qt low on oil. Has nothing to do with pressure.

My oil warning light is on when the oil level is in the middle of MIN - MAX on the dip. Is it OK?

Thanks!
