Can't get my cruise to actually 'work'. I have fitted the cruise switch and loom, done the 11463 code in VCDS, checked measuring blocks, all showing as working, cruise showing as activated in VCDS, also just to make sure deactivated cruise (16167 code) and it deactivated showing 255 where it should if no cruise on car. It has been reactivated again, but when I press 'set' it doesn't set.... Doing my head in now, any clues? What am I missing?
