If you own and drive a modern diesel car, chances are you have a (DPF) Diesel Particulate Filter fitted. A diesel engine can be susceptible to soot build-up, especially if you mainly drive around town or short or low speed journeys. DPF’s are designed to remove this soot build up as you drive, but over time they can become blocked and can stop working.
To avoid very expensive repair bills and to keep your car running as it should, we recommend regular DPF cleaning.
DPF’s were developed to meet ongoing changes in emissions regulations, and are now fitted to most modern diesel engine vehicles. This new technology has proven to be very successful in reducing emissions, but things can go wrong.

How does your DPF Filter work?

As you drive, harmful exhaust soot starts to build up inside your DPF reducing performance and fuel efficiency.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 the type of fuel and oil used, driving style and vehicle age and mileage.

Do I need to clean my DPF?

If you’re experiencing the following symptoms your DPF may need cleaning:
  • The DPF 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 system can cost as much as £3,000 at the main dealer, but in most cases, using a DPF cleaning product can rectify the problem. So, if you’re experiencing any of these symptoms, it’s important to get it checked out and Motorvation in Northampton are DPF Specialists.

Can I remove my DPF?

No! Following an update to UK emissions laws, it is now illegal to drive a car that has had its filter removed. DPF removal will also mean you will fail your MOT.
