My oil Pressure warning light in my (W124) 1985 300D goes on and off every now and then. I check the engine oil and it's like half way to LOW. What does it mean when the light goes on for a while and then off again? Does this mean low pressure? Low Oil level? Or do I have to stop the car coz' it might just die on me.

Thanks!


Francis

Your gauge should tell you if the pressure is low. Oil level sensor may have a bad connector or is malfunctioning. I believe it's attached to the driver's side of the sump. Take a look.

Thanks! What I also need to know is when your OIL PRESSURE SENSOR is OK what will cause it to light up? LOW OIL LEVEL?

Mercedes only have a (low) oil level sensor. Ain't got no oil pressure sensor light.
Up until a few years ago they had an oil pressure gauge, but that has been removed and replaced by malfunction indicator display in the instrument cluster...at least here in the USA.

Oil level light comes on when sensor in the sump gets uncovered for a programmed period of time. Gauge should give you the oil pressure. You can have good pressure but still have a LOW oil level. The two are not directly related. Oil level light tells you that something needs attention..
