Won't Come Out of Regen

So here's the scenario, my truck has been in regen for 170+ miles. From what I can tell up to this point, regen has been occurring at regular intervals similar to what I've heard from others on this forum. However, last week it went into regen on the way to work and has been in it for the last 170 miles. My daily drive is 13 miles from home to work and 14 miles from work to home. The display shows "Cleaning Exhaust Filter" about 5-7 miles each time after I leave home or work. This is after the truck has sat for at least 8 hours. I assume it won't regen until the computer recognizes that the engine is up to normal operating temperature. Then when I get ready to park and shut it down, I check it again and the display still shows it in cleaning mode. Shortly after the cleaning message appears, it is just a matter of minutes before the obligatory white smoke screen appears and covers the drivers behind me.

I have never seen the message in the display indicating that I need to "Drive to Clean Exhaust Filter." Although the distance is only 13 or so miles, it's at a speed of 35-55 mph.

Am I doing something wrong?

BTW- the truck is a 2010 F250 with about 4000 miles.

anytime you drop below 40-45 the truck wont complete the regen cycle. so everytime this happens it restarts. you need to take the truck on a little prolonged highway drive to get the temps up and keep the speed up so that the regen completes its cycle. i had this happen quite a bit with mine after a lot of city driving.

My suggestion. Get a tuner. It'll never go into regen again!!! (But yes, do what fx4 said it should fix itself.)

On this totally misdirected advice for you to get a tuner:

I would remain Leftist, and have the appearance of being Green, and be Trendy, and Socialist, and Big Government so you can pay higher taxes and be over regulated... Stay Stock!!!

Never mind the Regen is actually BAD for the enviornment as it burns 15% more fuel normally and 30% more in heavy towing, you can be proud to be a Greenie...

Never mind it gets rid of a little puff of smoke on acceleration in the cities at the cost of higher fuel bills for the rest of the country and higher overall exhause emissions...

Never mind the Prius costs more, has a bigger carbon footprint to build, and as soon as 1 in 10 to 1 in 20 are plugging in at your neighborhood, they will have to upgrade the ENTIRE electrical grid in your area, and that will be a bigger footprint than the Prius could EVER save...

Never mind the Al Gores of the world have something like 17 air conditioners in their mansions...

Look, being a Leftist, with no real job in your working life, with no real experience, being pro Socialist to take away from the "wanna works" and give to the "don't wanna works"..... Being that way don't have to earn a real living life, you just be Leftist trendy and Socialist and the appearance of Green and even You can even go all the way to becoming a Prime Minister (Australia) or a President of the United States...

Alright, I have had my rant for day, I FEEL BETTER NOW!!!

I have just proven I am definitely politically incorrect...

Thanks guys! I'll take a long run on the way home tonight.

I'm just surprised that Ford doesn't see this as an issue and do something about it. I realize the truck is not designed to be a daily driver and should be run hard with a load. But what about the guys that use it in their landscape business where all of their work occurs within a few miles. Given the truck's computer strategy, it might never come out of regen.

Oh, it will eventually just plug the filter and give you "LIMITED ENGINE POWER" on the message center, along with wrench and check engine lights.

Gotta drive 'er till she's clean.

Yea! What he said....

That "Snap Frozen Yank" (Canadian) "Big Angry Hillbilly" is absolutely right. Your DPF will eventually (soon) plug up all the way. You need to go for a long drive now and then and clean it out. Or do the delete system and run the straight pipe.

Barring those two options, you might want to sell out. As an amateur Techie of reasonable measure, I really don't think this engine is suited to small short trips all the time. You need to get oil temperatures up to disperse solvents and moisture, and long enough runs to clean the exhaust as well.. Maybe an older truck, 7.3 PSD or the likes, would suit you better..

That or go on a longer country drive every other weekend or go the delete..

Good Luck to you... lone Ranger in Oz.

No internal combustion engine (gas, diesel, veggie oil, propane, etc.) likes short trips. Like the Lone Ranger said -- need temps up to disperse solvents and moisture.

Needs about 25 minutes of drive time to complete.
