My 2008 F350, 6.4 want to continuously clean the exhaust filter. It started this morning on the way to work, (18) miles, and started again about 1/2 way home this afternoon and never finished. What causes this and what is the fix??? Anyone else had this problem?, I'm sure there are more...I just purchased the truck 3 weeks ago with 120k miles on it. It seems to run smooth as silk, just keeps cleaning the exhaust???
Thanks for any help!

 

DPF delete will fix it.

 

It's because of the short trips, and like Z man suggested do the DPF delete and don't look back your truck will thank you.

 

With today's emission controls, diesels aren't made to commute and be driven easily. They need to be driven hard and loaded down heavy.

 

Yep, I agree. It's a combination of the emissions system and the short trups. The newer diesels with DPF's will have issues with constant regeneration when not worked hard because the DPF doesn't get hot enough to burn up the trapped soot. Your options are to make a point of making a longer trip mabe once a week or so to heat up the exhaust/engine or delete the emissions systems.
Do you have emissions testing/inspections in NC? If not, I'd strongly suggest deleting the truck. If you do, I'd still delete it and plan on reinstalling it for inspections. I'm not sure about your engine, but on my Ram's Cummins it is basically a two hour job. Just reprogram the engines computer and replace the exhaust's DPF. We don't have inspections in Ga, but if we did I'd still delete.

 

You have to let the regen finish, or else it will just restart. Now if it doesn't finish driving hard in 10miles or so, you have a plugged dpf. Do not drive the truck farther than that as the 1600 degree exhaust will cause your turbos, egr cooler, heads, ect to burn to a crisp.

Get yerself one of these units.



and this to run it all.

Goodbye DPF. 100 dollar pipe or a full exhaust and a tuner....you will be happy you did. and your truck will love you.
Or i can sell you my full stock exhaust and you can put a 30k mile dpf on it instead.

 

If you ever get a chance to look at the inside of a DPF, you will be amazed that the trucks even run with them in place.
