Dpf

So how do DPF’s work? Diesel Particulate filters (DPF) or ‘traps’ do just that, they catch bits of soot in the exhaust. As with any filter they have to be emptied

regularly to maintain performance. For a DPF this process is called

‘regeneration’ – the collected soot is burnt off at high temperature to leave

only a tiny ash residue.


Why does my Diesel Particulate Filter get blocked?

Every vehicle type & engine combination can have differing reasons as to why the diesel particulate filter blocks. The rate of particulates generated by the engine, the quality of the fuel, quality of the or oil, driving style, even the location of the DPF in the exhaust system can all contribute to the filter blocking or not regenerating fully.
