How many miles (or kilometres) has the vehicle done?
Has the fuel filter ever been changed?

 

I have bought the car in 2021 January and did not change it since that. I bought it with 117000 KM and it is now 134000 KM.

 

I have same issue mileage its 123k and fuel filter was changed about 15k back.usualy show that message after few longer start stops. Fuel rail pressure difference 10-15bar lower than reference under load and 5-10bar idle. Sone when engine stop on lights ref value stay on 350bar but actual pressure plumes to 4bars are its that normal?

 

If the fuel filter has been changed it's likely to be the fuel pressure regulator on the HP pump of a failing injector. do you have any other symptoms such a loud diesel knock or poor cold starting

 

Hi I have the fault same code, and have changed the filter around 5/6 weeks ago as I thought that the filter may be casing the fault. The symptoms do include rough running when the Regen is requested and enabled. Fuel pressure seems to largely track the requested value.

I have
Had the PATS fluid added
Pats fluid pump replaced
Fuel filter changed
DPF cleaned and regen has happened

The issue now seems to be Regen Enabled ( notified from reader), rough running, and an almost immediate Service light / Engine light / Risk of DPF clogged / U3FFF (FF) fault

Latest screen grabs below - thanks in advance for any advice.

 

I cant see or hear any symptoms. Starting absolutely fine. First error came couple sec after started on trafic light and when cleared code. Drive around 100miles when second time come up right after few traffic start stops in short period.
