I see P2262 daily!

[CO6.7Cummins]

What I find funny is that on the Cummins website, they talk about testing this motor (with all the components we are complaining about) for the equivalent of a million + "customer equivalent miles." Yet, everyday when I sign on here, I read about people needing new turbos after 2,000 or 5,000 or 12,000 miles.

Who dropped the ball on this one? Dodge and Cummins aren't the first company to have an EGR system on a turbo diesel, why are these so prone to clogging? What about the turbo diesels going in big rigs that have the same emissions stuff on them? Are they blowing turbos every 5,000 miles?

My own theory about why the problems are centered around Dodge / Cummins right now is simply the quantity of EGR going back through the engine.

From looking at my monitor for EGR valve position mine is 94.9% open almost all of the time from idle to empty highway cruising with is the majority of what I do. EGR flows seem to be less as the load goes up, on hills and running heavy there might be as little as 7% to 40% but every possible second that it can it is 94.9% open.

Ford and Chevy are both running EGR on their light / medium duty diesel engines but I believe the quantities are less - just from lurking around the various message boards related to those two products I've noticed that their DPF DeSoot cycles (regens) occur at least half as much as mine do. I also have data (not at liberty to disclose the source) that suggests that with the EGR capped off on the 6.7 and the DPF in the system the soot delta pressure increase (a basic measurement of DPF backpressure or how clogged it is) is over time is greatly reduced suggesting a huge soot load increase due to the EGR, however EGR reduction can have a seriously negative impact on the Nox absorber that our trucks have been blessed with.

It is possible that many of those million customer equivalent miles were high load miles on a load cell or something to simulate towing conditions and not light load miles like many of us do, or the EGR mapping was different during the testing, or they only meant that the 6.7 itself was tested for that long and then turned over to Dodge who programmed the whole mess - who knows how much factual data is behind what the propaganda machine at Cummins / Dodge spews out.

What you said definitely makes sense - maybe that's why guys who run the hell out of these trucks report little to no problems over the long haul. Whereas a large number of us aren't towing 10,000 lbs 24/7 or climbing 11,000 ft mountain passes on our way to work.

The more I hang around this site the more anxious I am to rip off the EGR and DPF.

The turbo they replace with is the exact same one they put on at the factor. which is the cause of one of the problems... the metals they made the VGT out of are cheap.. they expand and don't operate properly under heat.

That is not a re-assuring comment and does not make me feel good about spending 45K on this truck.

I'm convinced.... DELETE, DELETE, DELETE! ! !

My blocker plates are being shipped from K2 next Monday and the following Monday I have an appointment at BADP for the 5" TBE Gen 1 with the Juice to clear the codes from the DPF & EGR.

It won't be long now.

im pretty sure enough of you could take legal action against chrysler to keep your warranties if you can logically prove the deletes get rid of the problems.

Someone get an Etest before and after the deletes.. see what happens..

[Riddler6.7]

i would be interested to see how badly the trucks fail the 2007 emmisions regs, after the deletes that is

I think Riddler6.7 has nailed it. What are the differences are they extreme?

Awesome! Guess what I saw today? P2262!

On my way to work, the check engine light goes on, take it to the dealer and it's the dreaded P2262. Only 3,168 miles on the odometer.

The guy said they clean them first and if the code still pops up, they replace the turbo.

How many of you guys have seen zero problems after having the turbo cleaned? Should I drive the truck like a granny in hopes of clogging it again, getting a new turbo and then doing the deletes?

thats what im going to do. If i ever get the dreaded code, im going to wait til they replace the turbo, then i will do the deletes directly after! Either way i will eventually do the deletes but that will decide when.

So I guess there's no way to just reroute the EGR so that it's not going into the turbo????
