Driving home from London on a hot day this happened:
It stopped after about 20 minutes of driving now the time is completely out.
I tried pushing the button and holding it down and fiddling with it but made no difference
Cheers for editing the link who ever did, I think it's stopped now when I turn it back on in the morning if it happens again ill reset the ECU, will help to reset it as 4WS playing up as usual any way.
