Hi

I got my Mondeo TDCI 1.8 2009 fuel injector 1 replaced six moths ago after the car cutting out on the motorway. Roll on a few months and the same thing is happening, car cuts out and goes into limp mode. Brought it to Ford main dealer this time and he tells me the injector I got replaced is not the same class as the other three injectors.

Would not having the injectors all the same class cause the problem to exist still?

The injector was replaced by a diel injector specialist and he is adamant it is not the wrong injector. Who do I believe? Ford said I need to replace the injector to have all the same class installed.

Thank you in advance for any help
