Sorry ronnie, but fords are rubbish. My as I said earlier, my mum had a problem with her tdci fiesta, kept going into limp mode and throwing the EML on, took it to for, plugged in on there diagnosit machine, what do you know, it needs a new fuel pump. My dad not happy with that because of the cost involved, took it to a imdipendent diesel specialist who also plugged it their diagnostic equipment, saw thT it said pump, but also took the time to check the whole system and found that there wasn't enough fuel getting to the common rail, which turned out to be a blocked fuel filter.
Fords will only replace parts that the diagnostic equipment says are at fault, they don't have the common sence or skill to dig deeper to find out what the real fault is when most times it could be something inexpensive
