Problem with my car as diagnosed by garage is an injector valve seating is breaking up and that is has become problem on the Ford Focus and fusion 1.4 diesel, has anybody else come across this problem? mine is a 3yr old 20,000 miles. garage says his had 5 of the same in the last 3 months, Ford say they have not heard about it.
