DPF regeneration is usually available in Engine ECU in actuator tests (not in coding) as

• Activate DPF Rejuvenate (PM) - activates particle filter regeneration
• Activate DPF Rejuvenate (S) - activates sulfur filter regeneration

Once regeneration is activated vehicle must be driven so as regeneration conditions such as temperature are met. You can watch progress of regeneration in live data view:

|DPNR DPF Status Rejuvenation PM |standby |
|DPNR Status Rejuvenation S |standby |

PM regeneration always performs also Sulful regeneration
