If you’ve made it to this page, you’re probably trying to figure out what a diesel particulate filter is and why it’s important. Well, we’ve got the answers.
In short, a diesel particulate filter (DPF) filter that captures and stores exhaust soot order to reduce emissions from diesel cars. If you have a diesel car that is 20 years old or newer, it is likely you will have one.
What it does
This filter is deigned to remove diesel particulate matter or soot from the exhaust gas of a diesel engine. If these filters aren’t maintained, or if tampered with there could be serious consequences for your car.
What causes a diesel particulate filter blockage?
Short journeys at low speeds are the prime cause of blocked diesel particulate filters.
This is why car makers often go as far as recommending city-bound, stop-start drivers choose a petrol car instead of diesel. Poor servicing can also cause blockages.
How to maintain a diesel particulate filter
Taking your car on a longer and faster journey, for example driving down the motorway will help maintain the diesel particulate filter. High revs will help this too.
Ensure you book in to have your car looked at if you get a warning light on your dash regarding the diesel particulate filter, as the quicker you get it sorted out, the less damage you are likely to make to your vehicle.
