    00778 - Steering Angle Sensor (G85)

    Greetings from Norway...

    I have some issues with the steering on a VW Polo 9N from 2003.
    The steering wheel was off by approx 20 degrees and the ESP indicator light went on.
    This seems to be reset if I turn the engine off, align the steering to the mechanical position of the wheels (straight ahed) and then turn engine on again.
    It lasts for about 200 meters and there we go again...

    So, I did a complete scan.

    I have performed the procedure for calibration the G85 without any errors, but it still only lasts for 200 meters.

    I belive that the G85 itself is faulty. Should I perform any other tests before replacing it?

    Recheck mechanical baseline positions again at components directly & for improper alignment.
