    The pressure sensor is located within the hydro unit and a repair kit is available, but it's not a cheap repair .

    UMMMM, interesting, the light comes on and off and the brake light also shows with the DSC.

    I have read in some forums that the is may be to do with the speed sensors, as i did have my front brake pads and discs changed. The mechanic told me that the brake sensor was damaged and he removed it and asked me to get another and he will fit it in, i have not got the sensor yet so could it just be its this the problem.

    If that was the case, then you would have a different error code.

    the DSC and the brake light came on again but went off and last couple of days have been off which is good.

    I think the problem is with the brakes, i had them changed and dont think they been bleeded properly, when i pump the brakes and run the cra its seems fine. Going to take to garage to get the brakes checkes as apparently the different preesures from the brakes can cause the DSC and brake light to come on and the fault code does not always mean that is the root cause of the problem.
