Well have been doing lots of test on cars with DPF s to see when a DPF burns off.
Well the most rapid percentage of burn off rate with the soot content dropping most rapidly was driving at around 1600 rpm in high gear on a slight incline.
The most staggering result was thrashing a car at high RPM and speed saw an increase in soot content in the DPF rather than a decline.
It's important to remember that when a car is in regen mode a constant speed without lifting off is most advantageous

Part of the reduction in burn rate at high speed could be caused by the ram air effect cooling the exhaust and increase in soot particles from high revs and high load !
So giving a car an italian tune up may not be so benificial as you think Jaguar x-type sport gone

As David Said plus I have been under and checked and I get a wee puff of the black stuff if i excellerate hard sometimes and catch it in the car head lights behind and also there is none of the clinking sound they make as they cool down after a long run. HSE TD4 Stornoway Grey ★ Rear Spoiler ★ Black Leather Interior ★ Panoramic Roof ★ Navigation with Bluetooth ★ 19 " Alloys ★ Alpine Stereo 10 Disc Auto changer and Ipod connection and lots of other nice toys ★

Wipe your finger inside the Tail Pipe, black finger no DPF, clean finger DPF fitted. On UK spec Freelanders they were an option prior to MY10, then became standard, have a search through EY's posts he has posted a diagram showing where the DPF is fitted. p****d off with a Digital Keyboard Warrior

Regeneration takes place every 190-560 miles depending on speeds, the slower the speeds the longer the regeneration. Should take about 20mins. A regeneration is requested by the engine control module when driving between 40-70mph.

I think fuel economy dropping slightly is another tell tale sign. 21MY Defender 90 S 3.0 D200

That's another reason why I have kept mine. As it is a 56 plate it has no DPf!

But then again, I have never had DPf issues on any of my other cars in the past. Freelander 2 HSE Lux 2013MY - Barolo Black with Ivory Leather. Alpine DVD - Privacy -Evoque 20" Dynamic Wheels and more to come.........

Highly likely that you will have a DPF. Freelander 2 HSE Lux 2013MY - Barolo Black with Ivory Leather. Alpine DVD - Privacy -Evoque 20" Dynamic Wheels and more to come.........

It's a pre facelift according to FL2Voodoo's gallery, so unless someone specced it with one as an option as it wasn't standard fit at that time. p****d off with a Digital Keyboard Warrior

My understanding is that DPF was standard from MY11 on, mine has one and never had an issue with it, high mileage though that will help.
Even during holiday periods with short runs never been an issue and with the number who come on here with a problem, I would say that it isn't really a problem.
