    E38 Oil Level Sensor Wiring

    Been searching the web sick, going through multiple wiring diagrams, but without luck.

    Problem is, the connector from my oil level sensor has gone MIA, therefore I need the wire colors/pinout for the sensor.
    Car is 2000 730d 142kw, though I doubt it would differ from other engines.

    Thanks in advance

    Pin 1 is oil temp signal to DDE, blue with green stripe.
    Pin 2 is ground, brown with green stripe.

    Let me know if you need any more info.

    I guess the diesel indeed has a different wiring. I have 3 pins and none of these colors.

    Thanks for you effort, much appreciated!!

    Sorry, I misread it as "oil temperature sensor" (they are also a combined sensor on gasoline cars).

    The pinout for the level sensor is:
    Pin 1: Power from fuse 22 (switched with ignition position 2), green with white stripe.
    Pin 2: Ground, brown.
    Pin 3: Signal to DDE, grey with brown stripe.
