I bought a 2015 f250 last june ---drove a couple of thousand miles--then took a trip towing my RV (8000 pound trailer) drove from Houston to Raton Pass NM ---800+ miles----engine light comes on Exhaust Filter overloaded-- Service---took to dealer in Trinidad ---they did a manual regen---all good ---3600 miles later getting to Butte Mt then same problem---dealer says filter NOT overloaded does another manual regen---800+ miles later same problem Durango ford dealer calls Ford keeps truck 3 days does a computer upgrade (I think just software)---all good no problem plus manual regen
fast forward 1 year---going back to Colorado---just short of Raton (almost exact same spot as previous year)----truck tries to clean end up with overloaded message get serviced ---have truck towed to dealer in Montrose---($700 tow bill paid by ford) dealer does computer soft ware up grade & a manual regen (that I have to pay) tells me that they see this problem on 2015 models recommends I add EXTRA cetane I usually use 4 oz per tank---up to 6 oz per---3 weeks later start back to Texas ---- problem reoccurs---no dealer in sight truck seems to be running fine doing short regens but always saying overloaded get serviced ----then like magic after 300-400 miles I get to Clovis NM (on Texas border) then regen starts last for roughly 40 miles get message regen drive complete) check engine light gone---as is service light out---no more warnings on monitor no problems since drove 600 miles home Truck now has ~~25000 miles of which probably 6000 are towing the RV
this is my 1st diesel truck---have owned 3 150s and had a 2007 V10 f250
Gotta say---after owning only Ford Vehicles for the last 30+ years I'm think about a Chevy or Dodge---I don't like having to spend my vacations
looking for a ford dealer ---
I cant believe I'm the only guy with this problem (after my conversation with the dealer in Colorado) I have a service appointment with my dealer Monday---but I gotta say I don't expect much help


any thoughts appreciated

 

There's a guy on the 6.7 side dealing with a similar issue while towing. Atleast you weren't getting the ruduced power message,I'm sure you would have mentioned it if you were. Hopefully crystal from ford service will be along soon and can help. Until then here's the link to the other thread.
