Cleaning Exhaust Filter
I was driving my 2008 6.4 today and it went thru a short "cleaning exhaust filter" cycle. About 2 miles later it did it again all the way home which is about 6 miles. Any ideas as to what the problem might be?
Thanks

maybe it didnt get to finish, they say if you stop or drop below 35mph it stops the regen cycle. I have heard that if it continues to regen frequently it maybe oil or coolant getting past the turbo which means or could mean turbo problems. I am still a fairly new owner to my 2008 f350 6.4 but so far mine regens about every 200miles or so.
What i do out of habit now is if and when i notice mine goes into regen, i try to get to the closest interstate (i live 2mi from one) and just get it out and run it about 70mph until its finished.
Wish i had more to offer you. Good luck

How many miles on your truck? Mine kept regening off and on like yours. I'd run the heck out of it on the interstate and would blow blue smoke for miles. My DPF was the problem. I had enough and deleted the DPF and put a tuner on it. Runs so much better, better fuel mileage and no more regens!

Went out and started it up now the "cleaning exhaust filter" is not on??? Hoping it was just stuck on and now it is ok. I only have 71000 miles on it. Probably will get the filter cleaned and it will solve the problem. Time for some additive I suppose. Boy these trucks are touchy.
Thanks!

Hey stroker350, I have been asking around to diffrent 6.4 owners as well as my old family mechanic who use to work on these for a living, fleet vehicles for cable and phone companies, as well as my current tech who is a master ford powerstroke tech, All are saying that 71k is fairly short in time to clog a DPF unless you dont drive it much or let it sit and idle alot, or use off road or low sulfur diesel instead of the ULSD. My tech who now has opened his own shop told me when we worked for ford during the time the 6.4s were all the rage, that ford would rather swap out a DPF under warranty instead of looking at the turbo chargers. Something that came to light was if the DPFs were clogging quickly and not burning out, the turbos were letting either oil or coolant pass by to the DPF which was plugging it up and you would never know that was the problem unless you know where to look. He said it was rare that the turbos went bad but those that did always looked like a DPF problem.
Now with that said I hope that isnt the case for you but it would not hurt to have that checked if your DPF is giving issues.
I wish you the best of luck. Cause these engines are great if cared for and maintained.

Whenever the truck goes into regen you need to keep driving it... Get on the freeway and keep going till its done. After a while you will be able to hear the tone of the engine change when regen starts and stops.
These trucks aren't grocery getters, you need to get them on the road and let them finish the regen cycle. You also want to limit idle time as much as possible.

DEF is injected into the EXHAUST (not the engine) solely for the purpose of reducing NOx emissions and has nothing to do with regen.

All I was saying is with the addition of the SCR after treatment it allows the motor to meet emissions while running less egr... Much better for overall health of the motor. But yes, SCR (DEF) has nothing to do with soot production or the regen process.
Many off road applications are able to meet emissions without egr now because of scr.

I was religious about driving until it completed a regen cycle. Murphy's law was that it would start about 2 miles from home, forcing me to drive another 10-12 miles. Never had a DPF issue in 120K miles. That was also one of the reasons I traded it for a 6.2 gasser.

I just got back from a 5K trip. Several times the exhaust cleaning message would come on and stay on for at least 20 minutes. Truck ran great, got 9.5 MPG pulling a 40 foot fifth wheel through the mountains of Colorado. Any thoughts about the exhaust message? This is a 08, F350 4wd with the 6.4 L engine.
