DPF damage

[rickr2007]

2007.5 LMM
I was rear ended and my exhaust system was damaged.
The small tube to the rear of the DPF is broken off. part # 25799002
I have NO codes, truck is running fine but I have been told the truck will eventually go into limp mode.
Part has been discontinued. Trying to get local diesel tuner to do a DPF delete but he will NOT work on truck due to it being an insurance claim
Should I expect limp mode?
THANKS for replies

that's for the differential pressure sensor. it's one of the metrics used to monitor the DPF and determine when to do a regen. if the rear is broken you may be able.to get by since that measures the pressure after the DPF witch should always be less.

is there any reason you couldn't just put another hose on it from the parts store?

THANKS hope you are correct
I found the part online
Broken part is the flared fitting on the end. Stainless.
I will keep on driving locally and see what happens

If there's an insurance claim on it, they have to fix it. Even if it requires a whole system

It will limp out bc it knows it needs to regen ever 500 or so miles.

Thanks for the replies
Update; Part (25799002)is discontinued and I cannot find any "Old Stock"
I used PB Blaster and the "Heat Wrench" to get the flare fitting out of the bung and I think the bung is damaged
Is the insurance company going to "Total" my truck because a $78 part is not available???????

 

[2004LB7]

unlikely. they will replace the hole exhaust before that

I have spent 4 hours trying to find parts and the Differential Valve (2799002)and DPF filter (15909020) are both discontinued and not superseded. GRRRRR!

are you sure you need a whole new DPF? I thought you said it was just the tube that broke

how about craigslist for those parts? sometimes you can find someone who removed the whole exhaust or is parting out the vehicle

Yeah where you located?

AZ GM dealer appears to have this part. New part, on ebay link

I sold my LMM and I still have my DPF. I know it would be expensive to ship because it is so heavy.

DNDJ Thanks for link. I think my DPF is damaged also, getting diesel exhaust smell in cab.
SFCJones I will keep that in mind. THANKS for your service!

Following up with Body shop and Insurance this week. I am "Building" and cannot go without a pickup. Looking for a new High Country, my LMM might be "For Sale" soon

Exhaust smell is most likely from the down pipe coming unseated from its v band clamp when exhaust was hit...
