Odd one.  Just got back from a long trip to the Pyrenees (1600 miles round trip) so was pleased to have the cruise control (standard version, not ACC) for the first 2 hours or so..... and then it cancelled itself.  I thought maybe I'd accidentally touched the brake pedal as the white CC light was still on but the green 'active' light was not lit.   After another hour or so it happened again about 4 times within a few minutes, then it was fine again for the next 3 - 4 hours until we were closin
