cleaning exaust filter-how often/how long?
I'm asking this ? for my Dad, i have had not had too much time to research this yet. we got the reflash done, and sence than its gone through alot of regens... we pulled a trailer 400 miles this past weekend(total pickup and trailer weight about 32,000 pounds), in that time it cleaned the exhaust filter twice, both times it took alittle over a half hour at 70 mph on the interstate.. i thought it was alittle much. And we don't even want to talk about milage... the dash said average was 10 when we left, when we got back it was down to 6... ouch.
So is that often of a regen and the length of it normal?

there has been alot of discussion about this issue. I don't think there is a clear answer. Not what you wanted to hear.
Regen's can be frequent or in-frequent based upon fuel quality, city vs hwy driving, loaded vs unloaded, high speed vs cruising at 50 mph. This list goes on.
What I would say, based up the wt you listed about 2 regens may have been warranted at that is quite a bit of weight.
You say it is a 6.4, what truck/gears do you have?

Regeneration should happen once every 150-200 miles and should last 15 to 25 minutes at 50 to 60 mph. If you shut the truck down during a regen once you warm the truck up the regen cycle should start back up until completed.
The faster you go the more regens.
The more weight the more regens.
The heavier foot the more regens.
Basically the more fuel you burn per mile the closer together the regen cycle.

i thought all this crap they put on these where ment to make them more enviromently(sp) friendly.. so much for that, buning 2 times the fuel can't be better for the enviroment.. that sounds like too often to me, the 08 dodge at my work, has only had one regen in 60,000 miles..
I bet it will settle down at little for you as time goes on. I don't regen but about every 600-700 miles unless really pulling hard.

I active regen about every 250mi. My typical driving is with the truck empty and cruising around 70-75mph. My understanding was that the truck would regen less when working hard (ie. towing) as the egts would normally be higher during those times and naturally do a "passive" regen......

Our trucks are NOT like a woman and regular! My experience is that it regens when it wants to. I would almost bet a power higher than we understand (computer power) tells that 6.4, now is the time. And, when it is done, it says, it is done.
Why do so many worry about it? Maybe I am getting too old to worry about my truck expelling burnt waste. ARE YOU?

I don't necessarily have a problem with the way mine regens and am very happy with the vehicle and it's performance.
i guess i'm one of the lucky ones.....it's just very bizarre how the same vehicle can act so differently based on varied driving habits, environment, etc.... and also be so unexplainable.

I drive a combination of Highway and town. I drive very conservatively to help with fuel mileage. My 2016 6.7 has 11,000 miles on it and the other day it regenerated 5 times within one day.
That just doesn't seem right.

My truck has been displaying "Exhaust Filter Cleaning. " For about 2 weeks now, the majority of my driving is around town, and occasionally a short stint on a hiway. Then a few days ago the engine light came on. I had it scanned, and it showed a P249F code. So toi took iot onto the in interstate and drove for an hour at 70mph to see if that would complete the clean. It didn't so I did it again for an hour and it still shows the message, and the engine light is still on. Now I'm thinking it's a sensor on the exhaust, but I've read were there are 4 of them.
How do I know which one it is and where are they located?
