I think if you are after 07 you might have a chance of it being available in the programming to be enabled or disabled by the dealer. Prior to that you are pretty much SOL. I had the opposite problem. Since my 07 is an American vehicle, I needed to have mine turned on to have it safetied in Canada. Dealer went to turn it on and they did not have an option to do so. I had to have a Ford daytime runner kit installed. If the option is available to the dealer, the toughest part for them is to spend the time connecting their laptop to the ODBII port. It is a simple check box they click.
