Doosan DX340 DPF and EGR fault solution

Excavators spend long periods idling and under light load; in these conditions the particulate filter (DPF) cannot clean itself, asks for frequent regeneration and blocks. The EGR valve and cooler collect soot; with a NOx sensor, pump or injector fault in the AdBlue (SCR) system the machine enters limp mode and work on site stops. The cause is diagnosed first; the software solution is applied according to the ECU type.
