Hi there good afternoon to you and sorry for the delayed response
My name is ***** ***** I would be happy to offer you technical assistance with your issueOk the fault code you have of p0251 indicates a fuel metering issue
This is caused when the fuel pressure deviates + or - 50 bar if the target value
The PCM detects this and in turn takes the vehicle into limp home mode (glow plug light flashing )This fault is commonly caused by a blocked fuel filter or worn injectors which leak off too much fuel under load causing a drop in fuel pressureThe first port of call with this code is to replace the fuel filter if this hadn't been done as it should be replaced every 37,500 miles
If the filter has been replaced or fault persists after the filter has been replaced
Then the injector an leak off test should be carried out (always carry this out when engine is hot
As this makes the injectors show true values
I always carry out a 4 minute idle leak off test and note resultsIf you need anymore help or advice on this issue please let me know
If you were satisfied with my answer /advice
Kindest regards ***** ***** and have a nice evening
Any positive feedback is kindly appreciatedBrian
