Hi diesel.gustav,
Boschfritze mentioned that low-quality biodiesel can cause significant deposits in the injectors (which is easy to imagine -> due to build-up).
It is interesting to know that there is still a filter present in the nozzles... then my operating room conditions when tightening the nozzle screws might be a bit exaggerated

.
How does the stuttering from the NHG actually occur

? Does the NHG provide an incorrect value at that moment, or is it truly a purely mechanical problem within the NHG itself

?
