Dpf question

Just drove 12 hrs to Florida in an 08 f250 with the stock dpf. For 3yrs when the truck has gone into regen, it would say"cleaning exhaust system" for a few seconds and then the message would go away and it would do its thing. Twice on my trip it displayed "drive to clean exhaust system" and then "cleaning exhaust system" would stay up on the message screen the entire time it did the regen. Why did it display different these two times? Is my truck trying to tell me it was about to clog up my dpf or something?

Did you take it to the dealer recently? They usually will update your ECM when its in for some other service and this could have caused the change in the way it displayed.
I would say your DPF is just fine. You will know when it plugs up, because if I remember correctly the engine will go into limp mode and check eng light will illuminate.

Yeah mine was just reflashed after they did all kinds of work before selling it, and it has both things appear on the screen.

PS that DPF thing sucks for MPG, holy cow. Oh and power lol.

I hate to sound like a broken record, but 6.4's are total different beast with deletes. You may consider deleting if you plan on keeping the truck for the long haul.

Haha, man are you right. Just did mine last night and really can't get over the difference. I thought having my 6.0 tuned, full turbo back exhaust, and all that jazz was nice, well it doesn't have anything compared to just a DPF delete DP back exhaust and canned tunes.

I can't wait for CAI and custom tunes. I just realized I didn't get my serial number for Gearhead to write cutom tunes from my tuner so I have to wait until Monday to send for them

How much does it cost to do the delete? I just bought an 08f250. Needs a little work but only paid 16'900 for it

When you drive for extended periods, the DPF is able to passively regen which helps to lengthen out the time between active regens (active regen = CLEANING EXHAUST SYSTEM). If the truck is in active regen and it gets interrupted a few times (not being able to complete the cycle), you will get the DRIVE TO CLEAN EXHAUST SYSTEM message, which is basically telling you to go find a highway and drive for 15-20 minutes (varies) to complete the active regen cycle. Eventually, if you never get to finish the active regen cycle, at some point you will find yourself with a CEL and a trip to the dealer.

The best way to deal with this is to TUNE & DELETE!

Thanks for all the replies. The last reply actually makes sense because in the week leading up to my trip, the truck tried to go through 2 or 3 regens and all my trips were short stop and go trips across town and the regens never completed. Thanks to all for the replies but the factory stuff is gonna stay on the truck. I don't care about huge hp or torque numbers and I have a hard time justifying the cost for just a couple extra mpg's.

Well alrighty then... But I should throw in that the more nannies you remove, the more reliable your truck will be. The way my truck is now, I get slightly better mpg than stock, but all the other benefits are the ones that keep me happy.

I guess when I start seeing those reliability issues due to the dpf,I'll eat crow for that last statement. Thanks again.
