Hello people, I’m about to buy a well-manufactured Mondeo Ghia X with the 131ps TDCI machine. I’ve also taken one in mind. Now I’ve been to the Ford dealer for retrofitting solutions for diesel particulate filters. Construction date of the vehicle would be 11/03. According to Ford, there is retrofitting DPF for all Euro3 machines, but for the Euro 4 machines only from the date of construction 2/2004. Maybe one of you knows what was changed from 2/2004 on? Thank you. MfG Jimbo99
