My 2002 2.0 l 130 tdci started to judder two miles after refuel. I went cold with the realisation of what I had just done. Stopped. Relay to garage. Drain, flush, refuel to brim. Restarted ok. The odd judder for a couple of miles then I cant believe this - 30 miles of driving like nothing happened. Then out of the blue doing 30 a SUDDEN cut out. Relay again but garage cannot find problem. Q if I damaged the injectors and or fuel pump would I have had the return to perfect running followed by cut out ? What course of action recommended ? With thanks. John
