2010 regen question
Pardon a dumb question. In February I bought my 2010 F250 XL CC with the 6.4. Since this is my first diesel, I started reading these forums for as much info as possible. Regen seems to be mentioned on a regular basis and everyone seems to know when their truck goes into the regen cycle.
Is it that obvious when the truck goes into the regen cycle? I ask because I’ve have 2800 miles on the truck and for the first time that I know of, the message “cleaning exhaust filter“ was displayed for a very short time and then turned off. I didn’t notice any difference in the truck’s performance and had I not looked at the message center I never would have known.
Was this the active regen cycle everyone writes about, or was this a passive regen cycle?

Oakman,
That was the active regen. In 2800 miles, I'm surprised you didn't see it earlier, but maybe the 2010s act differenetly than my 2008. Mine does a regen about every 250-350 miles, and the message center tells me while it's doing it (I also have an alert set on my Edge Insight). Other than the message center and the Insight flashing at me, I can hardly tell (performance-wise) that it's in regen. The biggest thig with regen, is to to "try" to let it finish before getting off the freeway...it will supposedly stop at speeds under 30 mph...it needs to get the DPF really hot to get a good clean. I really hate it when regen starts and I'm a half mile from home....

I used to tell everyone to not wast their time trying to figure out the regen/cleanout cycle. It will drive you nuts 'cause most of us want to know what triggers it and we want to know when it will happen and if we can gain control of it.
Plainly put, it will cleanout when it needs it and it happens more frequently when the engine is run with a load on it. Anything that makes higher soot levels will cause a more frequent cleanout cycle. More fuel consumption = more cleanout cycles.

Regen is like a "woman". They drive men nuts trying to figure them out, once you think you have them figured out, they do something different. They react differently under stress, never repeat a pattern and drain your resources ($$$). It's best to just...let it be.

They changed the message display area to only briefly flash the message (as there was no way to clear it before).. now you have to cycle thru the message center to see the regen status.
they have started pushing this firmware back into the older 6.4 trucks as well.
I think they did this change to reduce complaints..
if the message is there, then people will start to ask
why so long
why so often
what does it mean when the message blinks
etc.etc.etc
if you don't see it then you don't complain or worry..

It probably went into regen prior to 2800 miles you just did not see the 5 second message. Added to this that you did not notice any difference it more than likely did happen before.
I don't notice the notification half of the time but then when I go to pass someone, I realize its in regen mode.

[QUOTE=waverunner800;8687411]Oakman,
That was the active regen. In 2800 miles, I'm surprised you didn't see it earlier, but maybe the 2010s act differenetly than my 2008. Mine does a regen about every 250-350 miles, and the message center tells me while it's doing it (I also have an alert set on my Edge Insight).
I think maybe you don't have the latest flash. My 08 displayed the message the entire time until last November or December when they updated my computer during a CAC replacement. Since then it's really not displayed very long, maybe 5 seconds or so. Since then I've only actually seen the message twice.

DPF regeneration
DPF regeneration occurs as a result of execess back pressure or a computer generated regen at a set mileage. If the DPF starts to load up with soot the pressure sensors will send it into regen mode. Soot load-up is caused more by idling or any other activity where you are not generating enough heat to passively regenerate/burn off the soot. In that case the soot build-up is detected and the engine goes into active regen. As more and more ash builds-up in the filter you will get more regens. Ash is not burnable. It has to be cleaned out. If you want to avoid the expense of replacing your DPF you should have it cleaned out at about 75000 miles. The longer the ash stays in you get slightly less fuel economy because of increasing regens. You also run the risk of having the ash sinter (glaze) the cell walls in the DPF due to execissive regens. Once the cells glaze over your DPF is toast. A friend of mine had his filter cleaned out by a company called FSX near Seattle when he had 65000 miles on his '07. His miles per gallon went up 4 mpg and his truck ran a lot better/ more power.

First time I ever heard of anyone cleaning out the DPF. I regen about once every 150-200 miles right now. That's with trailer in tow mostly interstate driving.
With 135K on it, I kinda expected to have to replace the thing by now. Seems to be working fine though. I don't know how many miles I can drive unloaded between regen cycles 'cause I never drive that much without a trailer. I'm sure pulling around twice my weight justifies the frequent regen cycles so I'm not worried about it.
To be honest, I mean no dis-respect here, cleaning out the DPF sounds like a scam to me. Sort of like needing more tail light fluid.
