Loss Power? | DPF Warning Light? | High Fuel Consumption?
Passive DPF regeneration takes place automatically on motorway-type runs when the exhaust temperature is high. Many manufacturers have moved to using active regeneration as many motorists do not often drive prolonged distances at motorway speeds. Passive regeneration often uses a DPF additive (see below).
Active regeneration of the DPF is performed by the ECU triggering a post combustion fuel injection. This increases the temperature in DPF, burning off the soot and particles that build up in the filter. This type of regeneration can cause higher than normal fuel usage.
Fix may only be temporary
This can be prohibitively expensive as an OEM part, or potentially poor performing, as a pattern part.
Mix results, may clear some soot, but not ash
Removal is a potential MOT failure.
