I even took it for a ride to lakeside shopping centre just to get the miles in but still no light on. So i gave up and left it to the service this morning.
Now i'll need to find out how to turn it off when it comes on

orThis indicator flashes every 20000 km (12500mi) when the V-belt needs to be replaced. After changing the V-belt, reset the V-belt change indicator. To reset the V-belt change indicator, select it by pushing the “SELECT†button until “V-BELT Trip†is displayed, and then push the “RESET†button at least 1 second.
When pushing the “RESET†button, “V-BELT Trip†starts flashing. While “V-BELT Trip†is flashing, push the “RESET†button for at least 3 seconds.
If the V-belt is changed before the V-belt change indicator “V-BELT†flashes (i.e. before the periodic V-belt change interval has been reached),
the indicator “V-BELT†must be reset after the V-belt change for the next periodic V-belt change to be indicated at the correct time.
The electrical circuit of the indicator can be checked according to the following procedure.
1. Turn the key to “ON†and make sure that the engine stop switch is set to “ â€ÂÂÂ.
2. If the V-belt change indicator does not come on, check the electrical circuit.
Refer to “SIGNALING SYSTEM†on page 8-19.

Remove the left side panel and there is a loom with two plugs. The smaller of the two has only 2 wires with a jumper.
With the ignition switched on, remove the jumper for 3-12 seconds then reinstall the jumper.
