on my 1986 500sel euro i am having some difficult issues with the oil level indicator light. it will not go off!! i do not rely on this for anything at all, i am just one of those people that likes things that work correctly. when i first bought the car a year or so ago the light was on, i removed the subpan replaced the level sensor and all was well for about 2 months. then the light came back on. at first i thought it was low oil so i added some, light was still on. i disconnected the wire where it goes in to the block, light was still on. i unhokked the connection at the master cylinder that goes to the starter, oil pressure sensor and oil level sensor, light was still on!! so i troed a few different clusters newer and older with the same result. the only time i can get the light to go off is when i unplug the 8 pin connector on the back of the speedometer there is a good solid circuit from the oil level sender plug up to the round connector, it seems to me that something is backfeeding at that plug. but to my knowledge it has not been tampered with.
is there something i am over looking? any advice would be appreciated.

Have you rechecked that sender in the pan? My SDL would have the low oil level light come on constantly, $18 later it's off for good (new sender ).

i have unplugged the sensor wire from the firewall down to the sensor, completely eliminating the wiring from the firewall forward, and the light is still on.

Hrm, strange.

it would be nice to have the proper wiring diagram, i cannot be sure 100% it is same as a U.S. model

i did some reaserch and found the 560 and 500 are similar for the round plug, but no where alike for the square plug on back of the odometer. see below
if anyone knows what #5 grey/violet and #8 grey/blue and #15 brown green are that would be helpful, those colors aren't on the US models.
