Thanks for setting the record straight - I knew there were 2, one "normal" and another "bad". Hope OP got to a Ford dealer before the truck shut down.

 

Some say he's still "driving to clean" to this day...

 

I got the same message for the first time yesterday. Oddly though, I had towed our camper about 110 miles on Thursday, camped a couple days, and it came on when hooking up to come home. It should have cleaned up on the way down, no?

 

I had the same problem last week in Colorado with an 8000# trailer. Between Pagosa Springs and Durango and that message came on. After I hit ok 3 times the red warning Exhaust Filter Full came on along with the check engine light and low power mode. I called the Durango dealer after limping into my stopping place and they said go drive it without the trailer hooked up and see if it cleans the filter, otherwise we have to look at it.
I drove 30 minutes or so with the orange cleaning filter warning light on and after that it went off with all the other warning lights. Drove 700 miles in 10 days around SW Colorado and no issues. Hooked up to go home and started all over again between Pagosa and Santa Fe.
I have since been told that if the regen does not complete a cycle the system shuts down and the filter collects soot. I believe that is accurate because I used no DEF. The only fix is to have the dealer manually regen which costs a couple hours of your vacation travel, $150 and 1/4 tank of fuel. Been on the phone with Ford CRC for 2 days. It would be nice if they let you know when regen started, completed and how full the filter was before you get stranded in BFE with no cell service and a trailer tied to you.

 

2013 6,7 approx 48K miles. Hardly ever dpf msg but I sure can notice the jump in EGT temps.

 

bnpeters - I had same problem with my truck between Steamboat Springs, Breckenridge, and Col Springs. Hot Day, mountain driving at higher altitudes. Have talked to additional people experiencing similar problem in mountains, heat, higher altitudes. Every message, warning signals that others have mentioned. Col Springs ford dealer said unhitch trailer (16500 lbs) and drive south on expressway. Did about 60 mile roundtrip and problems went away, no more msgs, wrench symbols etc. Ford has not fixed or ever addressed my problem. Local dealer has no idea. I am in Alaska today, a regen happens any day that exhaust % gets to 95%. On travel days depending on stop location the mileage could be 350 to 500 miles and regen happens every travel day. Cool weather in Canada and Alaska and no regen problems. Over 6700 miles since leaving Txs in mid June.

 

OK guys, thanks. I have a good bit of drive time in DPF equipped trucks and this is the first time I've seen this exact message. I HAD JUST FINISHED TOWING MY 17,000 LB TRAILER FROM BILLINGS TO CODY. There is no way that the DPF should have been 100% full if the system was working right.

Since the incident occurred I have had one sort of normal regen with the monitor showing 97% full, the cleaning occurring and the monitor showing the DPF going down to 30% full. That it only cleaned down to 30% concerns me but I'm not sure the EDGE is absolutely accurate and again I have no code.

Sooo, who thinks it would be worth my while to buy the sensor and put it in the glove box? And if so what sensor?

Thanks.

 

My vote is to keep on trucking.... One strange incident doesn't require any action at this point IMO.


BTW... My truck has 124k miles and no major emission related issues to date. I did have a CEL earlier this year which turned out to be a defective Nox sensor which was replaced at a Ford dealer.

 

First bnpeters welcome to the site!
It took me a second to figure out where BFE was and it brought a smile to my face...I haven't seen that in a while!

 

This is my vote too. With regards to the sensors, the EGT sensors can be had for about $40 each, a lot of guys in 2011's and 2012's were keeping a spare as to not get stranded(I did too, never used it). That was fixed however in a later PCM calibration. I'm pretty sure the other sensors in the exhaust like NOX are quite a bit more expensive, and probably not worth having a spare laying around.

 

Just to ease your mind, I monitor with both the added % DPF Full screen and my Edge CTS and I have NEVER had the %DPF go below 30 during a regen, but have had it drop to 25 after. Much of the time, it only goes down to 35-40 and I had one or two stop reading 50 or 55. I added the DPF Load to the CTS and it always shows zero at the end of a regen, but the regens don't start until long after that PID shows 100%. But they always start when the %DPF Full screen shows Exhaust Filter Full.

 

Maybe that's what happened to me the other day. I was towing my camper and had elevated EGT's and I could see the % of soot decreasing from 80 something % and I knew I was getting some good ol' passive regen. When it got down to about 30% it went into a short active regen. I was wondering what the heck?

 

I haven't been on here much because this truck has been so good so forgive me for asking but what is a DPF full screen? Is that ssomething in the messae center? How do I get it?

Thanks

 

Your dealer can enable it or you can use Forescan and enable it yourself. It was kind of easy however there are a bunch of prerequisites you must complete before making it happen with Forescan.

I think im seeing a pattern here. PROSTICK bgpeters, gwg42 and I all had similar incidents with the DPF failing to clean when it should have.

We all had a day of towing at altitude on hot days followed by a DPF FULL DRIVE TO CLEAN message. Two occurances is coincidence three is a pattern, four is a trend. I know how to fix it like i did the 6.4. My DPF is still in my shop attic. Lol. I'm gonna start a new thread and see who else might have the same experience.
