After 48k error free miles, my DPF gave up the ghost while towing back from Memorial weekend. Only sign was the check engine light. No loss of power or other noticable signs. Dealer had me in and out in under 8 hours. New DPF, and a few exhaust sensors.

Mechanic did state that the DPFs do not last as long at altitude due to the fact that there is less O2 to burn junk off in the Cat before it gets to the DPF, plus towing heavy in the less dense air causes the system to run hotter leading to cracks in the DPFs.

Good info there. Very satisfied with how I was treated. Total bill to Dodge.....just over $1900.

Good thing airplanes don't have them [emoticon]
That could get a bit expensive every 50k miles after the warranty is up.
Wonder how the DEF engines will do?

It's really going to suck when they start going out a 110,000 miles. [emoticon]

This is why cold side EGR design which is accompanied by DEF NOX reduction is proving to be so successful. Far fewer EGR events, passive regeneration and less intrusive and less frequent active regenerations due to far less soot production.You mention hard running contributed to the demise of the DPF. In the new DEF equipped trucks, the higher exhaust temperatures are welcome. They are what creates passive DPF regenerations. Towing heavy, I have went over 800 miles without an active regeneration

I know, I know, the DEF system will need some maintenance down the road. The actual cost of this is undetermined as of yet. There are some 100,000 mile 2011's out there now and there has been no chatter about the DEF maintenance yet. Time will tell.

Good to hear yours was under warranty.

Yikes, that was not your cost was it? Warranty repair.

Kinda sorta good to hear, as this is why I decided to NOT go diesel, stopped
reading up on diesel and decided to wait for a direct gasoline injection big block

Still a maybe for me would be an older non-DEF/DOC/DPF/Urea/etc truck

DEF, DPF, DOC, Urea, etc plus all the of the plumbing is all going to become the
norm for all diesels...unless they invent something whizzy bang

Part of the lore for diesel is/was the attainable million mile goal of yesterday
without major costs

Good luck and hope you find a way to stave off that $1,900 bill coming up around 100K miles

What is good to hear? Hopefully you are not celebrating your decision to go gas someday because a diesel owner had a warranty repair...

NOx Adsorber Catalyst is covered up to 8 years/80k miles under law.

Thank goodness. [emoticon]

I have also heard that the design life of the DPF is 120k. Mine didn't make it. Could be the altitude and lack of dense air, could be other things. Had an issue with tail pipe soot and smoke about 10k miles ago. Took it in and they couldn't find anything wrong. Guess it was just a sign of things to come.

The one good thing about the EPA. The federally mandated emissions stuff generally has the longest warranty of any component on a given vehicle.

When did you move to California?
