On my recent great Alaska adventure, I busted the seal on my drivers front shock. Visited several Dodge dealers along the way and none of them would help me. The excuse was either "that's a special order part", or "our calendar is booked for weeks". I'm still driving on the broken shock.
The dealer I bought the truck from knows its broken, but the special order part I guess is on a row boat from China or Italy or something. Until it impacts my driviblity, I don't care I guess, partly because I'm just borrowing this truck from Fiat
Guess my point is, I'm not impressed with the "dealer experience" right now... might want to take your Ford to an independent diesel expert for a second opinion, as Ford seems to care about as much as Chrysler does.
