I don't know but it certainly doesn't surprise me with such short journeys.

Vehicles with DPF’s need to be used regularly getting the vehicle up to full working temperature with some longer trips for the DPF to work and self clean efficiently. (DPF regen)
I remember when DPF’s first came out people living in the channel island were having all sorts of problems as some islands were only a few miles long meaning a DPF would never work. I specifically bought the 2.4 because it didn’t have a DPF, have you considered getting it removed? Ride like you stole it!! If I’m not on a bike it’s because only a 4x4 will do… 2011 2.4 Puma 90 HT |

With a 1 mile commute, all you will ever do is progressively fill the DPF up. So whenever you then do anything any longer than that - it will attempt to regen 100% of the time as long as conditions allow.
Sadly there's not much you can do about this. Your drive cycle isn't OK with a modern diesel, it'll constantly fill up and eventually throw up a code with a full up DPF. All you can do is either do a commanded static regen every now and again, which is smelly, noisy, and rather pointless as you could be enjoying driving it somewhere to achieve the same thing..... or, every few days drive for long enough that you hear the injector note change and it doing it's regen, and then critically.... STOP doing a regen, i.e. the injector sound returns to normal. If you get it again having changed drive cycle and started driving further more often, then you'll potentially need to do that static commanded regen to get to a low soot loading, and try again. |

My 2013 averages around 130 miles between regens for short journeys. By short I mean under around 20 miles. When travelling longer distances I can get over 200 miles between regens. I’ve 90k on the clock so presume there must be a build up of ash reducing dpf performance. I use a scanguage to tell me how full the dpf is. I’ve never had the dpf led light up, but I can see how you could reach that point with such very short journeys.

That's why taxi drivers said good-bye to their diesel engines. Just look inside your user manual : you need service temperature and a ride on a highway for quite some time in order to get your DPF cleaned. We're not often on short daily commuter trips - most of our rides take 1h or even much much more. No DPF issues so far - the last MOT ended up with 3x 0.00 particulate matter. They didn't believe  |

Surely a one mile journey each way wouldn’t warrant driving?
I’d walk. Plus you won’t be burning in-necessary diesel doing a regen every 20 miles. On my 2.2, 15miles each way, so 30 miles a day, I’d see one regen every full tank or so.

I do low mileage in my 2013 2.2 with DPF, but try to do a regular decent run on my A road. ( 20 miles ).
Never experienced a problem but can't say I've noticed a regen. What are the signs of it taking place ? |

I have tried to attach the workshop pages which explain regeneration.

Interesting.
Fortunately all must be working well in mind . Thank you for the comprehension information |

Thanks guys - interesting stuff. The 1 mile commutes are about to cease and I'll be using the wagon properly again soon; good to know that I don't have a problem and it's to be expected with short journeys.

Don’t ignore the orange DPF light. You can run into all sorts of expensive problems if you get the red light.
Forced regens are not good. Try for a longer run at about 50 mph minimum until regen occurs when you get the orange light. |

Resurrecting this thread a bit. I watched my first dpf regen today but had no orange light etc. Been doing short journeys for 160 miles or so, then today I had a longer 50mph bit for 10 mins when the soot % went from 80 to 7 in a surprisingly short time.
Is it supposed to show the orange light every regen? |

I think it only shows the light if there is a problem. If it is just regenning routinely it won’t show the light, at least that’s the case in mine.

Orange light does not show unless the system determines that there is a problem.
Normal regen just happens. You can sometimes tell by engine noise or smell. |
