Well I went to the Ford main dealers yesterday, only to find out it appears this issue is known to Ford.
But they don’t know how to fix it at the moment! So they took some versions etc from my car and asked the dealer to tell me they’d be back in contact!
It was stressed though that it was not the instrument cluster panel, it was more likely to be a software fault. I wonder if Microsoft were asked to help out on that side of things!
Anyway, still got 63,000 plus miles on the clock, and still have no idea of my true mileage! Oh and to top it all, i still feel ill!
