2.0ltr diesel, scanner says fuel pressure problem, have changed sensor with no joy, now to change regulator has anyone done this?

Diesel it have to be coded !!

Thanks in advance

A full scan would be helpful. I would also look at the high pressure fuel pump as this can fail on high mileage heros.

It’s had a scan said fuel pressure problem, but drives lovely so thot regulator as no drop in power, only on idle !!

Sorted,,,, regulator changed was easy,

Idles lovely 👍
