Hi there good evening to you
Ok the P0251 dtc is a common one on the older 2.0tdci Mondeos
This indicates a fuel metering issue
The fault will lie with Either a partially blocked fuel filter or a worn injector
The fuel filters should be changed every 37.5k
If the fuel filter has been replaced /ruled out then the injectors should be tested for excessive leak off as its more common for older higher mileage vehicles to have worn injectors
Both these faults will bring on p0251 under load

The problem started not lng after the filter was replaced could this have anything to do with it? Or is it definitely injectors?

Hi there iam very sorry for the delayed response I couldn't access your reply
Ok this will most likely be a coincidence
But I would always advise a ford genuine fuel filter in case a poorer quslity part has been used
But a leak off test on the injectors will clarify the cause of This P0251 code
Basically if the fuel pressure deviates 50 bar +or - the desired value limp home mode is brought on and p0251 is set
