I have a recall on the window switch to be fixed on Friday, I have asked them to look at this issue then, I can remember before the first time it happened I had the traction control light come up on the dash which I thought to be a fault, I went home and housed out wheels and wheel arches , I thought mud may have done this due to wet weather and a muddy patch on the driveway. and a day or so before that i adjusted the rear park brake shoes ,maybe I caused this fault some how by activating the park brake during testing the adjustment and some how effected traction control setting, I remember reading somewhere there is some sequence activating park and foot brake to deactivate traction control and maybe I have accidently half done this and caused a glitch?????
I have good mechanical skill as I am a plant mechanic but was on industrial equipment and never was exposed to car computerisation.
