What is a DPF regeneration? 

A DPF regeneration is the process of cleaning and emptying the diesel particulate filter (DPF). 

Why does it need regeneration? 

Over time the DPF can become clogged with soot and debris, which can prevent it from being as effective at trapping harmful particles.

Why is a manual regeneration needed? 

The DPF can perform a self-regeneration, but sometimes this doesn’t happen, for example if the vehicle is only used for short journeys. If this is the case, manual regeneration is required.

Should I still perform a DPF regeneration even if one is not needed?

We do not recommend performing one if it’s not needed, as there is the possibility that some of the components become damaged during the process.
