Jan 18, 2021. #1. New Sprinter owner here. My understanding is that DPF regeneration must occur every so often in order for the emissions system to remain healthy, and that regeneration involves a cycle of "burning off" accumulated particulate to clean the filter, though the Owner's Manual doesn't really explain what is actually going on. Forcing a regen that often will break your DPF , the forced function is not intended for this frequent use and just for emergency , a normal regen while driving takes about 5 minutes to complete while a forced one takes 4-5 times that and will shorten the life of your filter with a LOT.

Owners of the new Isuzu MUX/D-MAX or Mazda BT-50 with the 3.0L 4JJ3-tcx, how often does your DPF require regeneration and how long does it usually take for the DPF to regenerate? Haven't had my light come on in my new mux yet but I can smell when it has done a burn. From memory it's taking it on a long sustained drive, maybe 20-30 mins of

Active regeneration takes around 5 to 10 minutes to complete, and normally happens every 300 miles or so depending on how you drive and how often you use your car. When active regeneration is taking place, you may notice a change in how the car sounds and feels – this is due to increased power to the cooling fans and a faster engine idling speed.

What Is DPF Regeneration? DPF regeneration refers to the procedure of cleaning and emptying the diesel particulate filter of soot that is created by the process of combustion. Burning off the soot particles requires heating the diesel particulate filter to a very high temperature.
