The message pops up when the computer decides it's time for an active regen. It is spraying Diesel into the exhaust stroke on the left side cylinders to provide fuel (temperature) for burning the soot in the DPF. A passive regen happens when conditions are such that the exhaust temp is hot enough to do the job without being commanded my the computer to spray extra fuel - such as when towing a heavy load. In that case, you won't see any message.

For the first time that I've noticed it this week my truck popped up the orange panel that a regen is required. It was mid week and it was getting short tripped in town so it never completed.
Today I was headed to the city and it came up a couple of times before I hit the highway and I hit the OK button to clear it. Once the truck warmed up and I was on the highway it came up again. After I cleared it the fuel mileage went down the drain, 5min histogram was 40l/100km. I finally showed a blue screen that it was complete. After this the fuel mileage was the best I've ever seen, easily .8L/100km for a round trip better than its showed before.
I'm going to get it in for an oil change next week as the oil level seems to be higher than it should. I've had the truck since Nov and put 3800km on it.

But I checked mine yesterday for the first time (2000 miles) and it checked perfect. A little dirty but that's to be expected but no growth. I was very please as I have committed to stay stock this time. Well I'm pretty commited.

FLL still has good areas. FMY sure has its share of not so good areas too...
I guess we all want what we don't have, since I can't stand the heat anymore. I want to go to an area with 9 months of winter and 3 months of poor sledding.

I'm new here as I just got my 6.7L a month or so ago. But I can absolutely tell you that other DPF equipped diesels make oil. My 6.4L made a lot of oil. So much in fact that I started draining (installed a fumota valve) down to a quart low and then topped off with new oil every 1000 miles between changes. That was helpful and kept the level stable. It also improved my oil anaylsis a lot. I finally tuned and deleted the DPF. Man what a difference.
But I checked mine yesterday for the first time (2000 miles) and it checked perfect. A little dirty but that's to be expected but no growth. I was very please as I have committed to stay stock this time. Well I'm pretty commited.

My 6.4 ran great, even with the emission stuff and that was the first generation. I rarely had fuel dilution.
I think you will find the same with this motor and how you use it.
