Thread: License Plate Light

  1. #1

    Default License Plate Light

    I got a message regarding my license plate light. I found the
    passenger light out. Bought a new light and changed the old one.
    This did not solve the problem. I checked the voltage and the
    12 volts was open. I then wired the left side 12 volts to the
    right side so I wouldn't get pulled over for a foolish reason.

    My question is, I need a wiring diagram so I can replace the
    broken wire that services the 12 volts on the passenger side
    license plate light.

    Actually, even better, how can you turn off the display for an
    error to begin with? I like being able to cycle through and see the
    time, temp, etc, but as soon as I turn on my lights, I get the
    license plate light error, then you can't do anything anymore. Any
    help would be appreciated. Thanks.

    The right side is fed by a grey w/yellow & brown stripe according to Bentley.
    Only God knows why the BM engineers decide two wires were necessary.

    Maybe I am saying something stupid, but thats my job here. If I understand your post, you are saying that you are getting the license plate light error message but the license plate light is actually ok. I thought when this happened it was usually a failed sensor.

    The driver's side light works, the passenger side does not. To make a quick
    fix, I wired the 12 volts from the driver's side to the 12 volts of the passenger
    side. The problem is, I still get the error message. So the wire for the 12 volts
    must be open. To fix it, I somehow need to replace the wire in the harnass,
    but that would be a nightmare. I don't know where the wire comes from.
    That's the problem. I need a wiring diagram.

    The wire comes from the LKM same as the other side

    I'd suspect a broken wire at the trunk hinge, Mine were all working but the insulation had come off on about 5 wires.
