W210 - Minimum Oil Level warning

[dukegrad98]

My new-to-me '98 E300D Turbodiesel had an oil change about ten days ago. Three times since then, while driving extended periods, it has fired off a "Minimum Engine Oil Level" warning, or something to that effect, on the digital dash readout.

I have tested the dipstick a half-dozen times, in differing circumstances -- engine cold, engine hot, engine running, engine off. Every time, the oil level is at or near the maximum level notch on the dipstick. I'm pretty confident I don't need to add oil, given that, and I hear over-filling these things can lead to pretty bad stuff.

So is this a sensor problem? Or does THAT much oil wind up in the engine rather than the pan at speed? Suggestions appreciated!

Cheers, John
