Further to my previous post, just wondered if anyone can interpret the below DPF figures such as ash volume, soot mass, regen etc?

Do these figures seem typical, mine is a 2010 van. 2.0l, 140 - (remapped by pendle to 170) with 62000 miles on the clock.

How do i know why DPF is regenerating? Is there any way of knowing while driving?

Does anyone else have any scans of theirs they can post as a comparison?

I guess you mean "when" rather than "why"? Without hooking it up to something like VCDS you won't know for sure, but general signs are slightly higher than normal idle revs and (in my case, very similar van to yours) odd wheezing type noises while you're driving, plus it will smell hot when you park up shortly after a regen.

By coincidence I checked mine only a couple of days ago and the figures don't look much different from yours. Your oil ash volume is higher (mine is 0.02l) but then yours is 3 years older and has done three times the mileage, so offhand I don't see anything to worry about.
