Clogged DPF???

Well, for a little over the past week, my truck has been showing the "Drive to Clean Exhaust" display as soon as I start the truck, but even if I drive it for about 20-30 minutes during the cleaning cycle, the next time I get in the truck and turn it on, almost immediately the "Drive to Clean Exhaust" comes back on. Took my truck to the dealership Friday, and it's going into the shop Monday for them to look at it. Its a 2011 with 27,000 miles. Also, another reason that I think that something might be screwed up is my mileage. I have been getting about 13 on the highway, its on 35" Toyo M/t's with the 3.31 gears, but my step dads truck is a long bed, on 37" Toyo M/T's with 3.55's and around town he gets about 14.5. Anybody else had this problem? What did they find wrong?

You may have a faulty sensor putting it in constant regen.

When you say faulty sensor.... What do you mean? Cause I have same problem. I'm in constant regen all the time. I also have the aFe stage 2 intake. Ford says its the intake.

Always put your truck back to stock when you take it to the dealer for warranty work or repair.

A little late for a reply, but the final verdict from the dealer was that my filter had become so clogged that it couldn't burn it self off. They did a couple manual regens and had the truck for a couple days. When I went to pick it up they told me that if and whenever it does mess up again to bring it in and they would order me a new DPF. Always a warm fuzzy feeling...

Im having the same problem with my 2012. It has 13k miles on it and it wont even kick to the regen. It just triggers a redundant pressure code (p20e8) and doesnt really have any guts goin over the mountain passes. (colorado) I bought it a week ago. the light has only been off one day. On all the rest...thinking about going back to duramaxes...never had problems with them.

Any ideas on whats wrong with the filter?

We ahve had a couple of our trucks do this. ended up having to replace the entire exhaust system along with all the sensors.
When it get to the verge of killing the truck you will notice the exhaust system almost whistling when you rev the engine.
The lack of GUTS going over high altitude areas could be the exhaust system, but may also be the lack of altitude capabilities of the 6.7L Ford turbo and software has been well documented for.
The 2015 engine is suppose to address the altitude sickness syndrome, we will have to wait and see.

No they weren't. Two were dpf equipped though. That didn't last long. I was really hoping to keep this one stock but it probably not gonna happen.

Yeah I was thinking of holding out for one of those. Maybe I should have. All my friends with 6.7's love them and don't have any problems on the passes. I think the dpf is clogged from what I've read on here.
