cold weather re-gens

[thedynoguy]

It seems that since the weather has gotten colder (below 30 degrees), my truck is going into re-gen every 250 miles. The truck is used for transportation only, no heavy loads/towing. When the weather was warmer, it would go at least 700 miles between re-gens. Any thoughts?

Mine regens when the exhaust is still too cold and it smokes like a mofo. Ford says it's "normal operation" and wont fix it. I have also noticed that it regens much more when it's cold.

That would make sense because diesels smoke more when they are cold. I've never had my truck with the DPF in the winter so I can't verify your findings aside from looking in my mirror and watching the smoke when its cold.

Hmmm..... Mine is mostly a daily driver and it regens once per tank (usually shortly after fill-up). This last tank it regen'ed near full and again with ~65 miles to E. That's the first time it's regen'ed twice. It's also the first time it's really been cold and it was the first time I saw any smoke - big white clouds this time....

I have noticed mine going into regen more often in the cooler weather also. It seems like every time I fill up it does it. It did it this morning and I noticed a big cloud of white smoke behind me. I was about to post about this but I am glad I am not the only seeing this. Mine also likes to go into regen when I am in stop and go traffic. I wish we had a way to manually start it so all that crap doesnt build up. I will be glad when I get my tuner and dpf delete!!
