This is another one that came over from TroubleCodes. Not my doing, though, he had already come over before I sent the "bait" email!

Yeah, we are eager/willing to help, but need response from the OP. Let's hope he is just off enjoying the holiday and we hear back early next week.

He donated to the TC site before coming here, so is kind of "invested" in us.

Thing is here, if you dont do a reset, YOU CANNOT DO A REGEN.

To do a reset, you need a proper scanner.

In most cases like this, customer just gets sick of this, and does a uree slash dpf delete.

But in this case, now in power saving mode, truck needs a scanner. No work around here.

Hence my first comment to this thread, I am maybe right and wrong. But I have encountered this before, and if you dont do a reset, you cant regen. Point blank, ford and even dodge have same way.

I know this is not helpful, op is already pissed off. throwing good money out window in tight times is hard.

But if he sticks around, maybe, us, as a collective, will save his truck from a guy throwing gas in it and calling insurance.

:rolleyes:

Dang, another victim of dpfe
Hey thanks for reaching out to me . They did not do a regen. I have lost confidence in the local "techs" at the dealership, I am no longer covered under warranty and have spent thousands chasing this thing. I dont know where to turn. State of ca issued me a temp operating permit till I get this thisg somogged, its my work truck and i am self employed, cant afford to lose for for even 1 day, I havebeen working 7 days per week which is why I did not respond to you guys,I would trade the truck in but there are no trucks availaible- am I screwed?
