What is A Diesel Particulate Filter?

A Diesel Particulate Filter or DPF is a component which removes soot from the exhaust gas of a diesel engine - a great thing for the environment.

All filters get blocked over time but in DPF's clogging is avoided by using high heat to burn the sooty residue and turn it into ash. However in short trip or slow city driving the exhaust temperatures don't get hot enough for the soot to burn-off, and the DPF can eventually get blocked.


How do I know when my DPF filter needs cleaning?

A warning light on your dashboard will let you know when your particulate filter needs attention - and you should have that attended to immediately to avoid the risk of fire.
