    2007 R56 base not S. I replaced the front control arm bushings, front and rear sway bar bushings. When I backed it out of the garage and turned hard left the DSC failed light came on. I pulled it back in the garage and checked to see if there was anything I missed. NO. Started it up no DSC failed light, backed out and turned again and DSC failed came on again and stays on. As I've been checking to see if I could find a problem. The bake pad worn indicator now is on. They both now stay on even if I disconnect the battery and clear it out. Car is up in the air with no wheels and now I have a P0503 Vehicle speed sensor. I've checked the fuses, brake pads & sensors, the ABS sensors all seem to be okay. Any ideas?

    Perhaps the sensor just pick now to go bad. Every thing is bolted back tight?

    Sounds like you accidentally disconnected a wheel speed sensor.

    Did you disconnect or damage the wheel speed sensors, brake wear indicator, or the leveling sensor that is attached to the driver side of the subframe?

    You need to find someone with a proper scan tool, Autologic, Autoenginuity, Snap-On, and so on and so forth. As long as it has the ability to read manufacturer specific codes, the Actron "free scan" that Autozone offers won't tell you much.

    Check the connectors to the wear indicator and wheel speed sensors, as well as trace the wires to see if you fatigued or broke any of them.

    Bought a icarsoft 910II. It doesn't connect to car. but when I was messing with it I got a steering angle of -1175 the next time I got 360 then 0 when I turn the wheel it stopped changing.
    New troubles turned the ignition on and the wipers started running and wouldn't stop. after turning it on and off several times they did stop.
    I think I may have pulled a harness loose or something. Will start looking for that next.

    When you did the control arm bushings, did you remove the steering spindle from the rack before or after finding out it has to be undone for the subframe to come out? You could have stressed the steering angle sensor or clock spring in the steering column by letting the weight of the subframe hanging from the spindle.

    I took it to the dealer. The mechanic said that to recalibrate the steering angle. He had to pull the steering wheel, move the cable all the way to one side then all the way back, then back to center. Put the wheels to center and put it all back together. Before doing the reprogramming. This is all if the spring isn't broken. We shall see how much it will cost.
    I just get the feeling when I'm talking to the mechanic that they're saying all this to justify the expense.

    You don't need to remove the steering wheel to recalibrate tie steering angle sensor. You just have to set it dead straight and the rest is done through INPA (factory software).

    But you can't charge dealer prices if it's that easy. :lol::lol::lol::lol:
