Clean running VEAs regenerating at fixed intervals?

[Borealis]

A while ago I read something interesting (it might have been somewhere on this forum) about DPF regeneration.

I already knew that the engine system is monitoring the amount of soot in the DPF, and when it counts a certain level of soot in grams, regeneration is triggered. But what I didn't know, is that in VEA engines if this level isn't achieved within 1200 km (745 miles) since last regen, it will be triggered at the 1200 km mark.

Therfore I've been resetting the trip meter after each completed regen. It appears that with my current V70/D2/VEA/2016, it is exactly 1200 km (to the nearest 100 m) between every regeneration.

Actually I hope that this could be a sign that my engine is in fact running quite clean, since DPF soot level always seems to be below threshold...

Not sure..... Here's my experience with a 2012MY D5.
Bought a Vida and DICE set up to do my own regeneration cycles as the Beast only does short journeys most weeks.
Plugged in four weeks ago, 16grams. Started a regeneration, then accidentally terminated when I touched the pedals.
9 grams
Rechecked a week later, 12grams.

I've been out today, thinking after a fortnight of short trips, with only two runs of duration greater than 15 minutes in there, and all urban, it would be truly ready..... 9.5grams
So it must be doing something to keep it low and not clogging up.

Passive regeneration happens whenever the DPF gets hot enough in normal driving. Active regeneration then occurs when passive regeneration has been insufficient to keep the soot content under control. I used keep an eye on mine using a diagnostic app and never noticed a regular DPF cycle happening, but I may just have missed it? A link to the source of information would be interesting.

I eventually lost interest in the DPF because it seems to be very reliable - at least on the VEA models - and I've never seen a post complaining about it! The EGR system, on the other hand...

Are you initiating forced regenerations with the car stationary? They are very hard on the vehicle and not something that is meant to be done regularly or routinely. Some manufacturers say that the engine oil must be changed after a forced regeneration initiated through diagnostic equipment, before using the vehicle.

Only the one time, and aborted.
I'm just monitoring the soot level. I can always take the night for an actual run to stimulate the engine to regen normally.
