    you will have to get the car plugged in on vag com or something like that to retrieve the fault codes once you have them you will have something to go by.

    Make sure once you have jotted the codes down clear them and see what if any returns strait away or you will be chassing your tail if you have loads of stored codes

    A6 ABS LIGHT.

    The ABS sensors can be tested with a multimeter. Set the meter to millivolts ,connect both leads to the pins in the connector and turn the wheel. a good sensor should read a voltage as the wheel turns past it.

    youd need an osiliscope to do this check that way.

    just get the car scanned for faults. then you can pin point where the fault is.

    you can buy vag com, or go on the vag com section of the forum and see which member is nearest you that has it, pm him offering beer money to help you. if its a sensor fault, he can also check the sensor signals via actual values as your driving.

    It needs to be plugged into a scanner/code reader to know exactly what part triggered the problem.

    If the sensor turns out to be ok, might be an idea to get the car up on a hoist and check if any wheels have been buckled from a pothole/kerb impact... although you would probably feel nasty vibrations etc as you drove along if it was an obvious physical failure like that.

    A buckled wheel would not cause the ABS light to come on as the ABS ring will be on the shaft and for that to move it would have to do the wheel bearing and you would hear that had gone if it was bad enough to trip the ABS

    Make sure the ABS sensor is located right, if its sitting in the wrong position it will cause a fault (had this problem before)

    Fairy nuff. Just throwing it out there as I vaguely remember hearing of an instance (admittedly not an A6) where a couple of buckled wheels were enough to confuse the ABS sensors... but you are right in that if it was mechanical, it would have to be severe enough to feel/hear something.

    As you were!
