I've found the that my cruise control does not always re-enable after being disabled while driving. The car is doing over 20mph but it will not enable or show what the speed the cruise control is set to. It will not work until I switch the car off and back on again. The car is booked in for a day's diagnostic at the garage. I'm not sure why it will take a day to scan for a fault code. Has anyone else had this trouble with cruise control?
