Sorry to bring up an old thread, but does anyone know if the DPF in the my12 is self cleaning or disposable?
If self cleaning what speed does it kick in, how often does it kick in and how much power does it rob from the engine?
Thanks guys for the info

2.4l pumas shouldnt have the DPF but will have the CAT
2.2L pumas should have both the Cat and the DPF in EURO spec as of about EOFY 2010/2011
AFAIK its not mandated in Aus spec or NAS spec yet (but cant be far off) so if you get one or not will probably depend on where your landy was manufactured.
I dont know of a DPF that doesnt have a self regeneration capability. It might be user activated by a certain driving technique or direct user control most are initiated by the computer automatically as required or when driving conditions permit. All DPF's can be dealer cleaned.
Guessing.
The Puma DPF probably follows the ford or Rangies cleaning process of waiting until you are using a driving technique that is favorable for burn off and not using full engine power so you wont notice the cleaning process.
Good point , I thought my 08 had one so have recently used Nulon oil for engines with DPF , about the same time I notice my engine getting a considerably louder diesel sound and blowing white smoke when pushed hard in the bush! Could this be the issue ? If it does not have a dpf then I have used the wrong oil. The sound is not right - louder when accelerating from 1500 to 2000 revs then I don't really notice it. Guess its due for a visit to the service dept for some correct spec oil and hopefully this with some tuning can sort out the sound. Still drives well though !Quote:

Only read the destruction manual as a last resort(and before SWMBO suggests it)
the DPF light (if it follows most of the other common DPF clean setups) only comes on if the DPF is approaching capacity and hasnt had a chance to do an incremental burn during normal driving operations.
