The DPF looks like a traditional exhaust silencer. Inside is a complex honeycomb ceramic structure designed to filter the exhaust gases while minimising flow reduction. By forcing the exhaust gases through the honeycomb structure. The particulate matter is deposited on the walls of the honeycombs, reducing the amount of air pollution. Once the DPF reaches a certain level of ‘Saturation’ it performs a regeneration cycle to burn off the particulate matter inside the filter. The regeneration cycle is known to start failing. This will cause the DPF filter to clog up and the machine’s engine to derate. Removing the DPF will fix this issue. Once the DPF is deleted in the software the DPF filter will need to be removed.
