DPF - Diesel particulate filters explained

Diesel particulate filters (DPFs) might not be the first thing that comes to mind when you think about vehicle maintenance, but they play a crucial role in keeping our air cleaner and our engines running smoothly.

Whether you're a seasoned mechanic or simply a curious driver, understanding how these filters work can help you appreciate their importance and maybe even extend the life of your vehicle. So, let’s dive into the world of diesel particulate filters and uncover the magic they perform every time you hit the road!

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 always 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 potential risk of fire. Examples of Diesel Particulate Warning Lights.
