This is the silent, but severe problem with the Isuzu DPD system. Unfortunately the reliability of the DPD and EGR has proved to be a real downfall to what is otherwise a brilliant truck.Nationwide Diesel Services assist our clients with accurate diagnostics & repairs to their DPD systems and can educate owners & drivers how to best manage these systems for maximum reliability.
Possible injector issue, boost fault, sensor failure or the DPD itself may just be clogged and in need of industrial cleaning or replacement. {Automatic regeneration cannot be performed frequently}
