What is a DPF (Diesel Particulate Filter)?

DPF stands for Diesel particulate filter, these filters are now fitted to the exhaust on diesel vehicles to trap soot particles present in the exhaust gases, helping them pass the Euro 5 and Euro 6 emissions regulations as set by the Clean Air For Europe program (CAFE).

How does a DPF work?

The Exhaust gases flow through small closed parallel passages in the DPF. The walls of the passages are made from silicon carbide and are covered in a layer of precious metals, these walls allow exhaust gases to pass through them but not the larger soot particles which are retained.

At Burwains Service Centre we have seen a dramatic increase in vehicles with DPF problems and in response to this we have gone on to specialise in this field through training and specialist equipment.

If your vehicle’s DPF light is illuminated call us immediately for free advice and we can help you.
