    My cruise control ain't working properly. Sometimes it works for a
    while and then just stops and won't re-engage. It appears that error
    codes aren't stored for the CC so I have to use an OBD2 tool without
    turning the car off.

    I got two recent error codes (on different occaisons) - N.B. I am
    trying to remember the codes.

    Speed Pulse Signal out of range

    Vacuum pump or regulator error.

    I do have a satnav system in the car so disconnected that from the
    speed pulse but the CC failed next day. There is no vacuum leak (its
    been tested) and the ECU near the fuse box has been swapped with no
    aparrent result.

    Any ideas?
