The dreaded P2002 Code

[Powersport Junkie]

Good Morning,
Fellow Ram owners. I drive a 2023 Ram 2500 6.7 Turbo Deisel. Purchased brand new. The truck has thrown code P2002 3 times. 1st at 5k miles, then again at 10K miles and now at 24K miles. 1st time the dealership just cleared the code. 2nd time dealership replaced the PM sensor, and they noticed a small dent/scratch in the DPF housing. I'm being told it needs replaced ($2,800) and it won't be covered under warranty due to the small dent. There is black soot in the tailpipe. Just wondering if this exterior damage is enough to cause DPF failure or could there be another issue? Does Ram make a protective cover to prevent future damage? The truck is my daily driver to the construction site, 50 miles a day in the mountains on dirt road and highway at speeds of 20-70mph. I tow small trailers and do put the hammer down frequently to clear soot. Please see picture of DPF filter exterior damage. Previously owned a 2016 Ram 2500 Power Wagon that the dealership overfilled tranny fluid and ruined my tranny, thus a bit skeptical of dealerships. Is this damage enough to cause DPF failure? Thanks in advance for any advice/ opinion. Jeff

There is a insulating/sealing material that is around the outside of the filter substrate, its possible that it was damaged, and depending on how deep the dents are the substrate could be cracked, you would have to remove the dpf and look in the outlet to see if soot is coming from the area of the dent or if the substrate is cracked.
Unfortunately with that damage, even if it's not the issue it gives them an out for warranty.

My initial feeling is no way, but nothing we say about that is going to change anyone’s mind. I think the insulation should absorb that minor ding. I’d inspect inlet/outlet for signs of failure with a borescope or by removal.

They just don’t want to do the work and are looking for ways to get you to pay out of pocket vs. what Stellantis will reimburse via warranty.

There is a TSB out for certain production date 2022 and 2023 6.7 DPFs that acknowledges a manufacturer defect that can cause DPF failure.

Also, DPFs are in a constant state of backorder these days if that’s any indication of how often these are getting replaced.

I would try another dealer personally.

Thank you Superjoe83. I did check the exhaust pipe and there is black soot.

Thank you 4FishLimit. I did look into the TSB and my truck matches the production dates. Called the dealership, they continue to try and blame it on the minor dent, acknowledge that the DPF needs replaced but won't order the part until they "determine the true cause" by taking it apart. Of course, parts are on back order and they can't even get the truck in till the end of January. Dealerships are definitely a hassle to deal with but I have no choice but to jump through the hoops. They are the only dealership within 100 miles. Thanks again.

Thank you, Flan. I'm kind of at the dealership's mercy on this one as I don't have access to a borescope. Trying to get it replaced using the Stellantis TSB, suggested by 4FishLimit but of course the dealership is fighting me on that one, parts are on back order and they can't get my truck in until the end of January. Thanks' again for your help.

Does anyone know if there is a protective cover available for the DPF? OEM or Aftermarket? Maybe off-road accessories. I did have much luck doing an online search.
Also, I should clarify the first time it threw code P2459. Thanks All!

If you’re finding black soot in the tailpipe, and also getting the P2002 code, I’d suspect a cracked filter media. Although it is unusual, if the truck is passing excess soot through the DPF, I would expect the Particulate matter sensor to be “counting” that soot and triggering a DTC indicative of too much soot at the tail end of the SCR. If you’re getting P2459 (regeneration too frequent), that would further lead me to think that DPF is compromised internally. Although I would struggle to believe that small external scratch would be the root cause. I’m more inclined to believe your truck has a faulty DPF from new. There’s been several 2022’s and 2023’s that generate P2459 codes and ram has a TSB out that would lead me to believe they had a bad run of the particulate filters.

Do you know the trucks date of manufacture?

Check it against this TSB

I would take it to a different dealership, especially if it is the same dealership that ruined the tranny in your power wagon,
Not all dealerships are the same and some have bad techs and some have phenomenal techs. (this was by experience)

If you think you are going to have to pay for the DPF to be fixed, I would look on Facebook Marketplace and buy a slightly used stock exhaust and replace the damaged piece then take it to a different dealership
