have a 07 140 multijet since new recently it started blowing black smoke and loosing power and going into safe mode and giving readins on the dash display risk of filter blocking/antipollution filter fault
Took it to the main dealer and was told it was the egr but they couldnt be sure took it to a local mechanic and found that the particulate filter was blocked completly so we blew it clean cleared the faults i drove it for a couple of days still blowing black smoke a week later took apart exhaust to find filter covered in sutt again so i returned to mechanic and after a few tests have come to the conclusion that the ecu is giving the fuel injectors too much open time letting too much diesel trough and causing the black smoke
can you reprogramme the ecu or does it need to be replaced
