If your car is an E30 ( 1983 - 1991 ) the oil level sender is located on the drivers side of the motor toward the front and down low below the alternator. It's in top of the oil pan. Unplug the wire connector and unscrew the sender. It has a fairly large black plastic round top. Pull it out of the oil reservoir and wipe it with a rag before taking it away from the hole. You might be able to clean it sufficiently to make it work correctly. To test it pull up on the float and test continuity ( ohm meter ) between the two leads. To install the new one clean off the surfaces, screw it in ( use a new rubber seal ) and plug the connecter back in.
Bolted into the bottom of the oil pan.
