HOW DOES A DPF WORK
As with any filter they trap particles, in this case harmful diesel exhaust soot particles, so they have to be emptied regularly to maintain performance. The DPF (Diesel Particulate Filter) needs to be cleaned regularly, through a process called regeneration. The accumulated soot is burnt off at high temperatures (600C) to leave only a residue of ash, effectively renewing or regenerating the filter, ready to take on more pollution from the engine.
WHAT CAUSES A DPF TO BLOCK
Every vehicle type and engine combination can have differing reasons as to why the filter blocks. The rate of particulates generated by the engine, the quality of the fuel, quality of the oil, driving style, even the location of the DPF in the exhaust system can all contribute to filter blockages or insufficient regeneration.
Generally, the problems arise in urban stop/start driving which prevents effective regeneration. A dashboard warning light or message will indicate the DPF is full. If you continue to drive in the same manner the soot build up will increase, further warning lights will illuminate and the vehicle will go into ‘limp’ mode. At this stage the only option is mechanical intervention.
