On some Fords (using the Ford IDS) you can write the mileage to odometer, but I think it can only be done on a new cluster, can not 'clock it' to a lower mileage and you only get one chance.

Some of these 'digital dash experts' may have aftermarket tools to 'adjust mileage' on a second hand dash.

£300 to program a dash takes the piss it takes a few minutes with IDS. Needs an ETIS log in or means of getting a code to sort the PATS.

Agree with RichieST -Would have thought most dealers with IDS would charge an hour at most to do it.

Look for a local mobile locksmith who has the kit to do it.
