[QUOTE=jimmy-320d;17813889]I dropped below just below a quarter tank of diesel and it started juddering again but as Borinous stated not as bad but £30 of shell's better stuff in and instantly it stopped, so thinking its fuel related or fuel pressure related, I bought some wynn's high performance diesel treatment, I stuck that in and brimmed the car with the same shell stuff I used earlier and have to say after a 150 miles the car is certainly feeling smoother and seems to pick up a lot better too and touch wood no juddering 😏[/QUOTE
If it re-occurs when it drops below half a tank again even with "good" fuel. could that be a fuel pump issue?
