Hi to all,

topped up eolys tank,plugged in snap on solus to reset counters.When trying to reset additive level, fault code 4 appears along with (fuel additive pump control module)?Presume this means the dpf system ecu is dodgy?Cant hear little pump in additive tank working when i try to prime system either.Cant clear fault & still reads fuel additive low on display??could this be the ecu?
