Hi Guys, I didn't notice the reset button so i'll look again tomorrow, the car is a 1997 model (facelift) mondeo Ghia X,
I did not remove the glovebox but I did have a good look around it and saw nothing, From the booklet it looks as though the button should be staring me in the face. If there is no reset button near the spanner symbol on the dash i'll remove the glovebox.
Thanks for the replies.
Regards Bren
