Went to tank it up before our run to the Thirlstaine castle do in the Borders tomorrow, got to the pumps and went to reset the mileage trip. The total mileage figure underliner went from highest digit to lowest digit at each press of the reset /display button rather than going from total mileage to trip mileage, set off from pumps and Speedo wasn't working! Got back to base and decided to disconnect the battery and "start again".....to no avail Speedo not working haven't looked at the wheel sensor yet. Any advice or past experience gents.
