Demystifying DPF regeneration

6 September 2013  

As the quest to reduce vehicle emissions continues at a pace, with even more stringent Euro 6 legislation set to come into force from September next year, so does the likelihood of workshops encountering a vehicle requiring regeneration of its Diesel Particulate Filter (DPF). The DPF is designed to remove particulate matter or soot from a diesel engine and, as a result, these filters will inevitably fill up and need regenerating to return them to optimum performance.

It is important that technicians are aware that there are three main types of DPF regeneration procedure on modern diesel cars: Passive Regeneration which takes place during normal driving, Dynamic Regeneration that requires ECU intervention and Static Regeneration that equates to forced regeneration with a scan tool.
