What is a Diesel Particulate Filter Clean?

A diesel particulate filter is a device that captures and stores exhaust soot in a bid to reduce carbon emissions. Since 2009, the inclusion of a diesel particulate filter has been a legal requirement for every new diesel car. If you have a diesel car that was manufactured on or after 2009, your vehicle will almost certainly have one.

DPF filters have been known to malfunction from a buildup of soot. This can lead to various problems with your vehicle, including a loss of power and poor fuel economy. An orange warning light on your dashboard will indicate a problem with your DPF. Should this occur, we strongly recommend taking your vehicle for a diesel particulate filter clean at a reliable auto servicing centre.

Though a large number of cars have a diesel particulate filter, not everyone knows what a clean entails. The article below will answer some of your most pressing questions.

What is DPF cleaning?

DPF cleaning involves the use of aqueous cleaning technology and specialist chemicals to reduce the soot emissions generated by your engine.

Usually, your DPF removes soot automatically using passive regeneration. Our cleaning service removes the excess soot that is preventing regeneration from taking place. Once the clean has succeeded, the subsequent storage of soot should begin to disappear and regenerate naturally.

How does DPF cleaning work?

Our experts will inspect your diesel particulate filter to assess the scale of the problem. This includes a test to check the blockage level. We will then use a sophisticated cleaning and drying procedure to remove the excess soot and ash. This includes the use of specialist chemicals that won’t cause damage to any other components of your vehicle. After the clean, we will test your vehicle to ensure the procedure was successful.

How long does DPF cleaning take?

A DPF clean can take as little as 20 minutes to complete. Where available, we offer DPF cleans on the same day as booking to ensure your vehicle gets back onto the roads safely.

DPF cleaning is the most effective way to unblock your DPF filter and restore it to full working order.
