    ABS Problem

    I have an issue on one of my TDI's with the ABS. The light is on and the ABS has stopped working. VAGCOM flags up the following error code:

    Address 03: ABS Brakes Labels: 8Z0-907-379-MK20.lbl
    Part No: 8Z0 907 379 B
    Component: ESP 20 CAN V015
    Coding: 10758
    Shop #: WSC 02154
    VCID: 4796EF7A656B4F7968-4AB4

    2 Faults Found:
    00290 - ABS Wheel Speed Sensor; Rear Left (G46)
    04-10 - Mechanical Malfunction - Intermittent
    01314 - Engine Control Module
    79-10 - Please Check Fault Codes - Intermittent


    I have changed the sensor and removed the hub and cleaned it - looked ok but error code still there - any ideas?

    I'm guessing there could be a problem with the Hub magnetic ring or the replacement sensor is also faulty. Anyone else had this problem?

    Thanks

    I have now fixed this issue - not sure if anyone else had had same issue:

    Driver (not me!) hit a deep pothole and not long after ABS warning light came on and ABS stopped working - VAG code as above. I removed the drum and the handbrake return spring had come unattached and was showing some wear. Cut a long story short - the spring had got jammed at the back of the hub - the hub has a magnetic plastic ring on it that provides the pulse to the sensor and this had worn off. Replaced the hub and all fixed! Tip for others out there.

    what a really bazar thing to happen, certainly a first in my book, but will lock that one away in the memory bank for future use - thanks for providing an update it really does help other in the future
