17’ f-250 regen issues
 

I have a 17’ f-250 Lariat 6.7 I purchased new 7 months ago. The truck will not go into auto Regen mode, the check engine light comes on with code p2459. This I’ll be the 4th time it has been to the dealership for a manual regen. I have a little over 7k miles on it and the dealership can not figure out why it keeps doing this. The first time the check engine light came on around this order: 1st time @ 5k miles, 2nd @6100 miles, 3rd @ 7050 miles and 4th time at 7200 miles. Has anyone had this issue or found a resolution to this issue?

More information will help.

What is your driving style ?
Do you tow a lot, haul, short trips, lots of idles, long haul ?

EDIT: Also, do you have DPF % turned on in the instrument cluster? If so what percentages are you seeing when this happens?

You're problem is your duty cycle. Wrong motor for your commute and city driving.

I'd recommend a commuter car, save the truck for towing and hauling.

That is not his problem. I use mine even more gently than does he. I'm retired and drive mostly low-speed, short mileage, -maybe 20 miles a week. Never tow, rarely haul. I just wanted a bad-assed truck. My truck does auto regen and it seems to do so very efficiently with the DPF % dropping very quickly once it goes into regen.

Ditto, except almost-retired.

I think he should escalate with Ford. This sounds like it is hitting 200% load on the DPF and going to limp.
My driving style is similar and it regens fine when it stretches its legs while warmed up.

EDIT: OP ask the dealer to turn on DPF% in the cluster, or use FORScan and a $29 interface from Amazon. I do keep an eye on it more than I should, but I like information

What jakematic said . Get your dealer to enable the regen screen or use Forscan to enable . :-X22

Nando, your duty cycle may not be ideal for a diesel, but it will work. You can enable the Exhaust Filter screen yourself with FORScan, but to avoid having to do that just ask the dealer to use IDS to do so. This will help you monitor yourself. The delta pressure sensors fore and aft of the DPF are what determines when a regen is needed. The dealer can easily test to see if these are working. The truck also needs to meet some other basic parameters for a regen to start...for example, engine coolant or oil temp needs to be a certain level. Perhaps your truck is running too cool.

Forget your neighbor. All brands of vehicles have issues now and then...just stinks when it happens to be yours. You'll get it resolved.

When the truck is brand new the DPF is extremely clean and might go longer without a regeneration. But certainly you aren't going 5k miles without one. Mine went about 1000 miles I think. Now its like every 500-700 miles. It's possible you just got unlucky and it tried to do a regen and you pulled into your driveway, or your work, or Home Depot etc just when it started and you shut the truck off. If that happened a couple of times the truck would need a manual regen done. But it seems strange. Likely there is some problem somewhere. There are plenty of people driving the same truck as you with the same driving habits as you and not having problems.

According to the owner's manual, an active regen will occur between 100-500 miles. Even if you have passive regen though heavy towing, it will still active regen at the 500 mile mark. It just won't take very long. Also, according to the manual, you can expect a regen to last anywhere from 10 to 30 minutes depending upon how the truck is being used. The manual is fairly thorough on the regen issue even accounting for low-speed, short distance, and stop-and-go city driving as well as how you should drive the truck during a regen. It's not nearly as daunting as some make it out to be.

If my truck was regenerating every 100 miles, I'd be upset. The only way I can see that happening is if you idle...a lot. I tow a lot. Right now, I'm towing a trailer weighing between 10-12k every day except Sundays. Even in the winter I'm towing sleds a couple of times a week. But none of my previous-gen diesel Super Duty trucks regenerated every 100 miles. I'm also not certain I'm seeing an active regen every 500 miles no matter what. If it is doing so, its extremely brief. Yesterday my truck started an active regen...the exhaust filter screen had gotten to 99% and I ended up shutting the truck off...it dropped to 95%. It has not started another regen as of this morning.

As a side note, I really like the previous gen that would at least flash a brief message stating exhaust cleaning had started. The new truck tells you nothing unless you have the exhaust filter screen enabled and watch the percent drop. Heck, even my Kubota tractor tells me a regen has started, and when it finishes, and when I need more RPM, and even lets me do it manually.
