you possibly have a faulty petentiometer on the throttle pedal,remove plug from pedal and check for water ingress..or a wiring fault,which would generally fail where the cab tilts and flexes the loom ,identify loom you require and check for chaffing...wire numbers are 4677, 4678 ,4679, 4166 ,4680 ..check them for shorting to earth and for open circuits with a mutimeter

Hi, it is an 56 plate with the xe upec engine, it does have an engine brake, I have changed the button on the floor as I checked that with a test light and it was letting a constant feed through, that was coming up as a fault so we swapped it for one out of our other CF and the fault cleared and shown the brake coming on and off when you operate it, but the problem is still there, we sent the truck out and it went about 6 times yesterday ?
Thanks for your reply
