Dpf
Hopefully someone can help with this, we have a 2015 D4, as we all know these suffer from oil dilution. To combat as much as I can I change the oil every 4k miles. I thought I would check the DPF on the iid and it read this, which I assume on the volume is not good? We do mixed driving as it's our daily. Do I need to force a regen or something else? Thanks.

Bit more info if that helps, I did find another thread but I'm having trouble understanding what the gap is telling me

This is taken later on in the day and the soot value has gone down but volume remains the same

As I understand it, if there is an issue with build up in the DPF that means it needs urgent burn off you will get an amber warning light. That gives you chance to burn it off with a 20 mins ( or so) run at reasonable speed. A red warning would mean DPF trouble I believe
. I'll check my readings of the parameters taken last Nov and post details here when I've found them so we can compare.Gary

So after asking else where I was given some more info which helped explain what I'm seeing on the iid. Copy n pasted.
The inferred 3.42, this is your grams measurement which is perfectly fine, when regenerating it gets it down to under 6 grams to complete so it's well within an acceptable range, think 32g is the limit before it won't regenerate off the top of my head, haven't seen one read anything but 0 on remaining volume, think it's an unused data channel/calculation
So it looks like the DPF is fine 😁

Thanks for sharing. Useful. Will check my historic readings. As mentioned, you would like to hope that this DPF cycle is self managing and we'll get a warning light if needed to advise us to take it on a run.Gary
