Oil Level Sensor E34 525i 1989

[Bill R.]

Unless its different on the euro cars you don't have a oil level light on your car. IF your talking about the row of green leds and yellow and red then thats the service due indicator. The more greens lit the longer time until the next service is due. Some of the cheaper models of e34, e36, etc didn't come with a oil level sensor in the bottom of the pan, they just have a block off plate, hence no wires for one.

That's the one I mean. The sensor is located in the bottom of the pan. My 92 has a wire that comes up the side of the pan and connects to the harness about halfway up the pan. My 95 doesn't have a wire on the exterior of the engine like the 92 does, and no apparent connector in the engine bay wiring harness. I was just wondering how that part connects to the electronics. Seems unlikely that the wiring would be inside the pan amidst all the oil.

which engine do you have? Such info is necessary.
But anyway, on all E32 and probably also on E34 the plug comes up on driver side left hand drive and ends here next to the battery plus post

I have the 2.0L M50 engine. I've looked under the oil pan on my 95 and unlike my 92 which is a 2.5L M50, the 95 sender doesn't have a wire coming up along side the pan or anywhere else that I can see. It seems to be working, although it always shows a green and yellow bar and that the car requires service, even after an oil change. It just never reads the correct oil level. I assume it's plugged in somewhere but just doesn't work right. I'd put the 92 sender in to replace it because I know it works, but, the 95 car doesn't appear to have a connector to plug it into. I assume that if the sender in the car was disconnected completely, there would either be no reading at all in the dash display, or I'd get some sort of message indicating that the sender isn't working right. Therefore, my assumption (probably incorrect) is that the 95 sender plugs in elsewhere. I just don't know where.

Look in the area next to the B+ pole, on my E32 it is a 3 pin black plug, similar to this one which is for the aux water pump
