If you own a diesel car then chances are you have a Diesel Particulate Filter (DPF). All diesel engines are susceptible to soot build-up, especially those driven on short or low speed journeys.

DPFs are designed to remove this soot as you drive, but over time they can clog up. 

To avoid expensive repair bills and to keep your car running smoothly, we recommend regular DPF cleaning.

DPFs were developed to meet current emissions regulations, and are now fitted to almost all modern diesel vehicles.

How does a DPF work?


As you drive, soot starts to build up on the walls of your DPF filter, reducing performance and fuel efficiency. To keep the system clean, a process called 'regeneration' is used. This is when the exhaust temperature rises to 600°C and burns off the soot, keeping your engine free of harmful chemicals.

There are many factors that can stop this regeneration process from working effectively, such as low fuel or oil level,driving style, vehicle age and mileage or even a fault in the DPF system.


Do I need DPF cleaning?

If you're experiencing the following symptoms your DPF may need cleaning:

  • The DPF or Engine Fault warning symbol has appeared on your car's dashboard

  • Loss of power

  • The automatic stop-start system isn't working

  • Poor fuel economy

  • Cooling fans run more than normal

A new DPF can be quite costly, but in most cases, using a DPF cleaning product can rectify the problem.

If you're experiencing any of these symptoms, it's important to get the vehicle checked by a professional to avoid any unwanted expenses. 

We have various DPF cleaning options available, depending on how serious the fault of your DPF is:


Option One : 


This is for drivers making lots of short trips, where the engine isn't getting hot enough to burn off excess soot.

Two products are added to the fuel system to help clean fuel system and DPF. 

These are a DPF cleaner and regenerator solution & fuel injector cleaner. 

These products should be used every six months to keep your engine free from build-up.

Option Two :   


If your filter has moderate soot build-up then the DPF Flush may be the only option to avoid a complete filter replacement. As part of the Deep Clean, our technician will inject a special cleaning & flushing agent into the filter to remove the blockage.
