Distance in miles between regeneration

[Kiel0777]

As rusty says leave it be or you will become paranoid, there isn't a logical reason to it they just do it then the computer thinks it's required, some are short and some are full regens based on distance , driving style etc. If you want to keep an eye on it just check once a month and keep an eye on your light. Even with a new dpf there isn't a set parameters. I work for VW and they are the same although if you are low on fuel on the VW they won't do a regen, need half a tank of diesel.

Just find it strange as the first regen went from 80% to 8%....this one went from 48% to 36%?and only 120 miles between?
