Active regeneration is accomplished by changing parameters in the engine to increase the exhaust temperatures in the DPF. This requires precise knowledge of engine parameters and access to the
2020 2500 SO frequent DPF regenerations. Over the past 6 weeks, my 2020 Ram 2500 tradesman Cummins standard output engine is going into Regen every 30-60 miles. Truck has been to the dealer several times. They have replaced air filter, ccv, done the CP4 to CP3 pump swap, serviced the DEF system, etc. Truck has 34k miles, this started happeningHaving done a static regen on the car last night, I took the Zafira on a 40 minute drive on the dual carriageway today. After the static regen, Opcom set the Saturation level at 78% so that it would do a dynamic regen soon after. But after the 40 minute drive the saturation was at 82%, and despite the dual carriageway driving it still hasn't1. Passive DPF Regeneration. When the vehicle is moving in high speed for a long distance, the exhaust gas will be automatically heated to the temperature high enough for burning and cleaning the carbon soot particles in the DPF. In this way, driving for 30 – 50min at a high speed, the DPF generation process will automatically be completed.
As long as the above is followed, if vehicle senses that a DPF regeneration needs to be carried out it will do so automatically without the need for any diagnostic tools!!! Another thing you can do, is to use either the more expensive diesels such as BP Ultimate or other premium fuels, or a good diesel additive.Active Regeneration. Since many drivers do not use their cars to drive long distances on the motorway on a regular basis, manufacturers had to come up with a different way to clear the DPF of particles. They came up with a system in which active regeneration is activated when the amount of soot gathered in the DPF reaches a certain level. In
The next suggestion was to force a regeneration to try and bring the ECU back into alignment. On the previous 2 occasions the dpf light has been triggered by the ECU I have driven it literally 100’s of miles on the motorway and it will not go off without a forced regen by the garage. David.Added a bottle of forte DPF cleaner first. Sat in car with the revs around 2100-2400. Took about 10 mins for the engine temp to get to around 80C. Left the revs running for about 10-15mins. Oddly after 15 mins the revs dropped to 2k and stayed there regardless of how much I pushed down the accelerator.
