What is a DPF and how does it work?

A DPF is an abbreviation for Diesel Particulate Filter. This filter is situated on the exhaust system of most modern diesel engines from around 2005 onwards.

The design of the filter is to catch particulate matter otherwise known as soot produced from the engine to help reduce harmful matter being emitted to our atmosphere. Once the filter has reaches its threshold limit for particulate matter it runs through a process called regeneration, this is controlled and activated by the ECU (engine control unit)

The regeneration process involves the operating temperature of the the DPF to raise to such a point where it “burns off” the particulate matter. The ECU constantly monitors the DPF system but can't always detect any underline issues, this is where we come in.
