DPF Regeneration
What Is A DPF
Regeneration?
DPF regeneration is the DPF cleaning process, which is designed to remove carbon build up from the filter elements inside the diesel particulate filter itself, when it becomes partially blocked.
DPF regeneration is automatically initiated by the vehicles ECU (engine management system) as part of the normal operation of your diesel engine.
Sensors measure pressure differential between the entrance and exit of the filter (which is part of the exhaust system), and when carbon builds up inside the DPF filter and creates sufficient back pressure, the DPF regeneration process is activated to burn off the carbon build up.
This DPF regeneration cleaning process is normally achieved by injecting additional diesel into the diesel particulate filter, which generates a high temperature inside the DPF filter.

How Does A DPF Regeneration Happen?
In order for this DPF cleaning regeneration to take place, certain conditions have to be met, such as engine temperature, speed and distance/time.
Details of these will be found in your vehicle’s handbook, or you can find out by contacting the dealer or by searching on the internet for your make/model/engine.
The DPF regeneration process will usually take place during your normal driving, but other times you may see a light on the dashboard indicating DPF cleaning is required.
This usually means you need to take your vehicle on a run for 10-15 miles at a reasonable speed (usually 50 mph+), but consult your handbook or main dealer for specific details.
Sometimes a DPF regeneration is not enough for effective DPF cleaning, and specialist cleaning processes will need to be carried out to unblock it.
