dpf exhaust cleaning???

I know this may b a dumb question. But could someone explain how the cleaning works. When,how long it takes and whats the best way to get a good clean or it to do its thing. I drive it mostly in town and pull a camper about 5-8x a year. So I may only put 20-30 miles a week on it. When driving in town the cleaning message comes on, but I never run it long enough to finish. Also I think I read that it will tell you exhaust cleaning complete. Even when traveling I don't think its ever given me this message. Thanks for the help...Chris

I've been told by Ford that cleaning process takes 15 to 30 minutes depending on your speed. The faster you are going, the faster it will clean.
If you don't let it complete, it will start the regen then next time you drive it. As for getting a "completed clean message", I"ve never seen such a thing.

I believe the canister collects soot to a certain level. Then fuel is dumped into the cannister and rpms get very high in order to burn off the soot. THis is very basic explanation.

I can tell you that mine would regen every 40 to 60 miles. Never give a finished message.

You should get a system message that says something along the lines of " exhaust drive clean complete". maybe not those exact words, but I have seen it several times on the 2010 i had. Ive yet to see that mesage on my 6.7L

Not all have the exhaust cleaning complete. Mine doesn't. Drive about fifteen miles over 30 mph and that should do it. Use the system check on your display to see when the regen cycle ends. Don't stop the regen cycle too many times. You will get a drive until exhaust clean is complete message. The poster above is right, if you keep stopping the regen early, you're putting a lot of fuel in the motor.

As many have said. Delete the DPF. I'm sorry I waited so long. Totally different truck. Better MPG as well.

That's because it's been removed with later flashes. Now the only way to see if it's in regen is to hit Setup followed by Reset and let it cycle through the display. The only vehicles that still have the message being displayed are vehicles that haven't received the last two flashes.

Check your local laws first. Some states are stricter then others in what they look for annually or every other year during inspections. Others have had roadside checks similar to DUI checkpoints. Also, make sure your prepared to revert to stock every time you go to the dealer for warranty work or even oil changes as you never know when a Ford rep will be there and see your vehicle. If your still ok with all that, then go for it.

My 08' does it about once every couple of weeks. I do mostly in town driving as well. I try to get it out on the highway and let it complete a full cycle without interrupting it. If I don't let it complete a full cycle for long enough a message will come up that says"Drive To Clean Exhaust filter" and then when it's done it will say "Exhaust Filter Drive Complete"
