DPF Cleaning

Autoparts UK LTD offer a ‘same day’ DPF (diesel particulate filter) cleaning service throughout Surrey & Sussex and a next day service throughout the UK.

The Flash-clean system works by using a pre-heated chemical solution that is forced through the DPF at pressure and pulsated to remove all particulate matter, oil and all other residual deposits.

This process is available for all types of vehicle, including HGV’s, commercial vans, buses, catalysts, Euro 6 and SCR’s. This versatility comes from the design of the Flash Cleaner, which contains advanced software that allows the machine to adapt to any type of DPF or catalyst. This process ensures that your DPF will be restored to original factory efficiency.

What is a DPF?

A diesel particulate filter is a trap that collects particulate matter from diesel vehicles. All diesel vehicles built after 2009 should have a fully functional DPF.

A diesel vehicle will periodically regenerate to clear the particulate matter (PM) and turn it into ash – this regeneration process takes between 5-10 minutes. If the vehicle is stopped or not up to temperature the regeneration process is retried again three times.

An unsuccessful regeneration will result in the vehicle going into limp mode and a clean will be needed. There are products on the market that can clear the DPF without removing it, if this is unsuccessful then a full clean will be needed.

Why does a DPF needs cleaning?

our diesel particulate filter is there to capture excess soot, which would otherwise be expelled from your car and into the atmosphere. All of this matter will continue to build up until your filter is completely blocked.

What happens next? Your fuel economy will reduce, you’ll see a drop in power, your cooling fans will be running overtime and you’ll be kicking out some pretty harmful exhaust fumes. Eventually, you’ll need to replace the filter altogether.
