Hi folks, my 2006 1.8 tdci c-max fuel warning light won't go outdespite filling up! It is still counting down from 50 miles and comes up on the display as soon as the car starts. The gauge itself on the dial is working ok. I've looked through the manual and found nothing, I even tried a mock fill-up again in case it is a sequence thing such as perhaps the door over the filler capis on a switch and needs opened to activate it etc but nothing so far. Has anyone had a similar problem or know what may be the cause? Many thanks...Dave W.
