The ones I have fitted did not allow mileage adjustment, ( But Mondeo's and Fiestas do. ?? )
I have even fitted a used instrument cluster to a Fiesta and upped the Mileage from 20,000 to 40 odd thousand. ?? I thought that once they had done a few miles they couldn't be adjusted using Dealer Tools. ( but that one could )
I Record the original mileage on the invoice and leave the mileage at Zero. As long as the customer is happy with that situation. As thats what he gets from the main agents anyway.
