    I have checked the fuses and they seem ok.
    ABS not working and light stays while driving.
    Was thinking maybe a relay has failed or something(not too expensive)

    Anyone able to help me out with this one?

  2. Most likely a wheel speed sensor, bit It'll need scanning to be certain.

    I think that it is most likely the brake pedal switch.
    I had the same symptoms on an Astra.
    Switch was sticking open-circuit.
    It would work for a while if wiggled. Try jamming the brake pedal down with
    a krooklock or similar wedged to the seat, then operate the swich manually.
    Get someone to watch the brake lights.
    Replacement switch was about £10.

    (I later had an open-circuit speed sensor. This also caused the ABS light to
    illuminate, but brake lights continued to operate normally).

    Good Luck,
