Hello, reading fault codes on a ford transit connect using forscan, seems to show "wrong fault codes", the fault codes from the beginning was the nox sensor the glowplugs and the glowplug control module however all these have been changed but still gives the same fault codes, the car itself notify about the dpf being clogged but that doesnt seem to be the real issue, it seems that it doesnt allow the automatic regeneration of the dpf, while searching the fault i noticed that the engine cooler fan runs even though the engine is cool, the temperature on the dashboard shows normal temp, forscan does not give any fault codes about the cooler fan, could it be that the automatic cleaning of the dpf is not allowed because of the engine cooler fan running all the time and what would be the reason for it to run when engine is cool since it doesnt show fault codes with engine hot or cold.
Thankful for answers!
