DPF Regen Information

There are three different ways of performing DPF Regenerations

Passive Regeneration (Automatic)

Passive regeneration takes place automatically,
It is done on longer high speed, when the vehicle speed and exhaust temperature is high.?

Active Regeneration (Automatic)

The ECU checks the soot loading has reached level (usually around 45%) and starts what is known as PCFI (post combustion fuel injection).

This injects a small amount of fuel into the engine after the main combustion cycle, increasing the temperature in the exhaust and triggering the regeneration process.

DPF light on the dashboard will flash to alert the driver that the regeneration process is in progress.

Keep driving until the light goes out, The process may take 5 minutes up to 25 minutes.

If the process is interrupted and the regeneration cannot be completed, the ECU will activate ‘Reduced Power Mode’ or ‘Limp Home’ mode.
