Hi I'd get it plugged in and check for any fault codes modern cars store most of the faults and should point you in the right direction just swapping parts for new ones can get quite expensive and can take a few goes before you find the fault there that many electronics on modern diesels, it could just be a sensor, only easy way is to get it plugged in or even take it to a diesel specialist, they come across similar faults all the time and may know the cause from experience cheers Joe

i would first check for diesel/fuel at the injectors, plus correct pressure too. change fuel filter, check all air sensors, along with air filter, EGR valve cleaned and check for correct operation under vacuum pressure. then connect up to ECU (electronic control unit) which after all of the checks done above should give you a closer pinpoint of any other problems if any? good luck ..... dave
