I need to keep the level between the middle and MAX to keep the stupid light off. I've only had this problem on my '87 300D (even with two new sensors), never on any other 124 that I've owned. Go figure. Could have something to do with the revised oil fill quantity... was originally 8.5 quarts, but MB later reduced this to 8.0.

The '86 performs in an identical manner.
I've got a suspicion that the oil cooler plays some part in the illumination of the light. The light won't illuminate when the engine is cold...........it's got to be fully warm after a decent run on the highway. Once illuminated, it cycle depending on grade, engine temperature, or curves.
The only way to keep the light off is to keep the oil level at, or near, the full mark.
