Can anyone help please. I have a Ducato based 2007 Lunar MH and on the end of the right hand stalk is a button to alter the clock and change the different readouts from the computer. It appears to be stuck and the only reading I can get is the average trip speed which is about as useful as a chocolate fire guard. What is more important is that the current mileage can't be displayed which is a must for its forthcoming MoT. Has anyone experienced this and know whether its repairable or is a case of finding a replacement? The Fiat owners handbook is about as useful as knowing the average trip speed.
