[Need help with this problem]

Hi thanks for replying. The engine runs and am not really sure about misfiring or rough running. To a trained ear you would tell in seconds but i dont know much about them and couldnt tell. I will need to check the wiring etc get a ohms metre

[Need help with this problem]

This code has came up on my nissan quashqai 1.5 dci ( 11 plate ) 

all 4 injector faults cylinder 1,2,3,4

Was wondering if anyone knows if it is indeed the injectors or maybe a sensor of some kind because the injectors are pretty expensive
