I purchased a 2017 Lariat ultimate on Saturday! Got a killer deal on it. So started using forscan today. The exhaust filter is showing 99% full. The truck only has 250 miles on it. Is this normal?
My truck is pretty new still (only 660 miles). I had my DTE calculation set to normal initially but around mile 400, I switched it to towing. Then around mile 530 I noticed my Miles to E drop quick. It dropped 2 miles for every 1 driven. I figured I was in a clean cycle. So far I only have a scanner hooked up and if I am reading this correctly, my average regen happens every 290 miles. This didn’t make sense until your posting. I must have missed the first one since normal DTE calculation didn’t show such a drastic change while driving (or I didn’t even notice it).
People make too big a deal out of the Active Regen. The computer turn it on when it's needed.
Seems like the MAX distance is 500 mile and the computer will do a manditory regen.
250 miles is not unrealistic.
Stop worrying about it and let the truck take care of it.
x2....this is why I have no interest in enabling the dpf% screen. Who cares? It's like worrying when your water heater cycles on in your house....let the machine do it's job and move on.
Pretty much what Mr gray AZ says but it is good to know what normal regen is. When I am city driving the regents are in the 300 km range, lots of short runs, stops and starts and cold starts. When highway driving no load, up in the 500 to 600 Km range, in colder winter, in summer or with load, about the same. Difference is once add load and long runs the %soot hardly ever gets up past 0%, and it still generates as its set too. Just good to watch it regen and the %soot go all the way down to 0. I pretty much have stopped watching it now, cause it does it on its own. But now I know what to watch out for, what's normal. If I start to get warnings to drive until clean I know some thes up.

Actually, its quite useful. If you can avoid it and do a manual regen before you're towing a 10,000 pound trailer up a mountain, you can actually maintain speed. Regen's suck alot of power. So yeah, there's a BIG reason behind it.

I went with an Edge Insight to monitor the different information, that is not readily available on the dash cluster. What I have learned, is the DPF% screen everyone talks about is not the indicator everyone thinks it is. Through nearly 9000 miles, the DPF% has never hit 100% to trigger a regen. The highest I can remember is about 85%.
This winter it was the 500 miles since last regent that was kicking it off, even with the DPF% down in the 30's (It did not seems to ever build in the cold weather). Now that it has warmed up, it is the 'grams per liter', hitting 8.38 nearly every time.
So for the OP, short trips kill that DPF%, so its possible that on the lot, it was moved a lot. Start it up, move it 2 rows over, shut it off, there is 1% added. Few days later, shop boy fired it up, drives it to the wash bay, then back. there is another 1 or 2 %.

Bingo ^ that's it. My average distance between regens is around 260 miles right now and I do mostly interstate 3-4 hour trips. Had a short regen yesterday in-town that dropped the % from 100 to 79 then shut off but, it was an average 35 mph trip in-town only so the exhaust temp never really climbed above 750-800 or-so.
