Forced DPF Regeneration (Service Regeneration)
A forced regeneration is a DPF cleaning cycle started with a scan tool when normal regeneration has not succeeded.
What is Forced DPF Regeneration (Service Regeneration)?
It is done when soot load is too high for passive or active regeneration. The engine runs at raised speed and high exhaust temperature for some time. It is usually done in a workshop with the car parked outdoors. Finding the reason why regeneration failed is important, for example faulty sensors, EGR problems or only short trips.
How it works
The control unit injects extra fuel to raise exhaust temperature and burn the soot in the filter.
Why it matters for your car
Exhaust parts become very hot; keep the area clear of flammable materials. If soot load is too high, the filter may need cleaning or replacement instead.
