That did actually cross my mind as a possibility. I have added myself a note and if the opportunity arises, we shall investigate. http://www.gap-diagnostic.com/

Which is probably why Land Rover removed it  http://www.gap-diagnostic.com/

How quick does the DPF fill up if you are travelling slowly?
I am taking my 2.2 across the Pyrenees in May and we will be potting along pretty slowly most days. I'm reading this and I'm a bit afraid I might get stranded! |

Active regeneration generally occurs every 250 miles (400 km) although this is dependant on how the vehicle is driven. For example, if the vehicle is driven at low loads in urban traffic regularly, active regeneration will occur more often. This is due to the rapid build-up of particulates in the DPF than if the vehicle is driven at high speeds when passive regeneration will have occurred.

My experience, not with the 2.2 but with my RRS TDV8, but the reason why I'd like to see the option implemented.
1. Was on a week end in Piedmont's mountains with 2 Defenders, off-roading, driving slowly. End morning of the second day I had the "DPF full" message. Had to park my car and continue on someone else car to avoid going in protection. We had a ~20 min drive on normal roads(around 60/80 Km/h) not enough to get the regen, but maybe a forced one might have worked. Going home it took a long time on highway before the message cleared. 2. Driving on normal roads but at slow speed I had the "DPF full" message, was not far from a highway, so went for the usual "high" speed drive to clear the message. Unfortunately it did not clear. I had to go to the dealer to have them do the forced one(on the road). Luckily they did it for free, but would be better to have the option to do it myself, especially if it happens at the beginning of the week end(as it usually do, thanks Murphy  ) |

In an emergency, could you disconnect the t-box ends of both propshafts and "drive" for the required perod at the required speed? As long as the vehicle thinks it is moving it should allow you to do this. Would this work?
I am so glad I have a 2.4 with no DPF! |

I guess that would depend on whether the speed requirements are a "do this because it will get everything hot enough" in which case no, or "do this and once you've clocked up enough miles you're OK", in which case yes.
You'll have to put a hydraulic pump on the transfer box and load it up |

I rather assume that the speed requirements are mainly a "do this to get enough gas flow through the exhaust to support combustion", in which case it might work.
if I was stuck in the bush with a blocked DPF I would certainly give it a try! |

I don't see the point of going to the main dealer if all they do is what it says in the workshop manual: "driving the vehicle until the engine is at its normal operating temperature and then driving for a further 20 minutes at speeds of not less than 30 mph (48 km/h)" as that can be done by yourself for free! They must do something else as well? |

Well, I followed that procedure few times and it always worked fine.
That particular time it did not work, did more than 20min, tried twice, then went to the dealer as I did not want the car to go in protection. They plugged the pc into the OBDII plug, started the software beginning the process and went for a drive, cleared quite quickly. |

Well, today it happened again, on my TDV8.
Got the message "DPF full", did the usual procedure but no success, drove more than 3 times the usual distance for the regeneration. Weather conditions were maybe a factor. Luckily I was able to borrow the dealer tool. Plugged in, started the "Dynamic Regeneration" and went for a drive, the message finally cleared. We (or at least I) need this function in the IIDtool |
