Hey,
I have a Citroen Jumper 2011. It has around 125k on the mileage.
I replaced two of the diesel injectors this summer, and the garage had problems programming these. Turned out the common rail pressure was too high. They was able to reset this and then program the injectors. The noises went away for around two days and then came back. So I have now replaced the common rail pressure sensor, but the noise is still there. Any suggestions for what this can be?
One this I have noticed though is that there is no noise when the car stands still or when I depress the clutch and rev up the rpm. It's only when I'm driving the sound is there.
Is there anything connected to the clutch, gear, transmission or similar that can make a noise similar to injector nocking?
