    Recently my DSC, brake and ABS lights on my dash have been coming on. This is on a 2001 E39. When I put new rotors and pads on this week I was pleased to see that the sensor wire to the left rear wheel was missing. I thought that was the cause of the problem. When installing the new sensor wire I found I had nothing to plug it into; in other words it has been missing for quite a while. Does anyone know how I could drive this for 20K miles with no wire and no warning lights on the dash?


    Thanks,

    The rear sensor is (usually) on the right rear wheel. There are only two sensors - front right and right rear.

    You probably are going to have to have the codes read out to find the problem.

    Missing wear pad senso

    Floyd,

    Thanks for your info. I wish when I ordered the pads and rotors they had told me I only needed one wire.

    Now I need to find out what's causing the dash message. I've looked with my code reader but will look again.

    Good. I notice that I said "front right". That should be "front left".

    Sometimes those connectors are hard to plug in. Also could be a bad wire - use a circuit tester to check continuitiy. Don't forget to check the brake fluid level.

    But my guess is it's a bad wheel-speed sensor.
