They actually cut open the DPF to check it, then they "float" it and put it in an oven overnight. The welding back costs $150 so the cost of the cleaning is $750.


I put 113,000 miles on this DPF before it clogged up with ash so I'm thinking if $750 will keep me within emissions limits and buy me another 100k miles, that's probably the route I will go.

UGH, OMG, WTF and whatever. Is this where the snake oil peddlers have gone? The DPF and DOC are physically different components. If either one is truly beyond the point of system recovery, replace it and try to find out why it failed in only 113k miles. Your money will be better spent.

But then, some may suggest that the best/least cost option may be to "delete". I'm guessing this won't be your choice.

Re: The Bleeding Edge

The message I got on my EVIC when my 2014 JGC went into limp mode was that my DPF was 100% full. From what I've read on the subject and from what I heard from the Jeep service technician working on it, a regen does no good at that point due to the fact that the DPF is plugged with ash; nowhere for it to go.

Of course the dealership is saying I need to replace the replace the DPF with a new one but $2,000 - $3,000 is crazy. I can't believe that national trucking companies with huge fleets running these things are replacing DPF's on every truck in 100k miles.

So it seems that cleaning for $750 is a viable option. I purchased this vehicle with the idea that I would run it as long as possible, perhaps 250k miles. I would not have made the purchase if I had been aware that I would have to spend $2,000 - $3,000 on the exhaust system every 70k-100k miles.

Gotta be a better option.

Re: The Bleeding Edge

Hey Treeguy - how much time at any given worksite do you spend idling the diesel? Putting a tune that turns off the EGR would certainly help the longevity of your engine and exhaust system.

I apologize for saying that replacement is the only option. My point is your dealer seems only willing to follow what the "factory" recommends in this situation. I can see their side. Attempts to clean are not without risk.

What triggered my previous comments was mainly the description of the process and price for cleaning you were quoted. This is totally out of line and shows me that the outfit has no understanding of the ED emissions system. You would be better served to fine a diesel specialty shop that does. There must be one in your part of the country. Snoop around on the RAM sites.

What led up to your vehicle getting to this state is of particular interest. I would pressure the dealer to seek some restitution from FCA. That will at least get there attention. Besides, at $2000 wholesale for just the DPF, the price is already ridiculous.

Hope you get some acceptable resolution soon. Then go back and consider Nordic1's last post.

Re: The Bleeding Edge

Thanks for your ideas.

I haven't done near enough due diligence to know if $750 is a reasonable price point for the service offered.

You are welcome at any time to throw the "he don't know squat" flag on me but my understanding is that ALL owners of these EPA mandated DPF systems will be dealing with this at some point if they own their diesel vehicle long enough. Just because a DPF system fills up over time does not mean it's defective; it was only designed to have a certain capacity and since I have a lot more miles on my vehicle than most on this forum, I'm having to deal with it before most of you.

I will certainly look closer at some sort of tune as well.

Same for me. I think the DPF system is the only thing NOT covered in the MaxCare, so at the first sign of any trouble it's getting deleted.

Like many others, my plans are to keep this vehicle for a long time, so I'm not willing to put up with a recurring problem when simple removal is so much cheaper.

But you're learning fast and everything you've said is fact.

Space limitations are also a major factor affecting DPF design size/capacity. I just went out and looked at the one on my 3.0 L Spriinter van and it appears to be twice the size.

The quote you got may be reasonable for the type of DPF the company is used to cleaning. The problem is the process they've described is typical for a heavy diesel and not necessarily applicable to these smaller components that aren't designed to be cut opened and cleaned. There is also more work mentioned than should be necessary.

I was a bit too quick in faulting your source of the quote since they haven't had eyes on the job, and this is what do. If it's possible or practical at this point, I'd suggest taking your Jeep to them so they can see what is actually involved. They may revise downward or suggest something altogether different.

What it really boils down to for me is that there has to become an order of magnitude cheaper solution for the inevitable routine maintenance of this critical component. Cat converters on gassers can run twice as long, cost half as much to replace, and won't leave you limping home. Hmmm... I wonder if the MOPAR parts division or someone else is looking at remanufacturing these things.

If it isn't covered, it's because they know it's going to have to be replaced sometime between the end of the emissions warranty at 80k and before the 120k end of the MaxCare.

It's not just the DPF that's not covered; the maximum care policy specifically excludes anything exhaust related. For example, the SCR catalyst is excluded too.

Do you think "everything exhaust related" includes the 4 sensors that monitor exhaust? I ask that because the code 0428 that came up when my check engine light came on referred to the Bank 1 catalytic converter sensor reading screwy. Apparently that sensor is on top of the transmission housing so the cross member had to be unbolted, transmission lowered, etc. As usual the sensors themselves weren't all that expensive but the labor was the killer.

Re: The Bleeding Edge

Emissions equipment is covered under the 8yr/100K miles federally mandated (US EPA) warranty. It doesn't need Maxcare coverage.

Regarding the DPF and cleaning out the ash, if done properly, you can get it back to about 95% of new from what I read. The ash itself is not necessarily what the filter is trying to keep out of the environment, so blowing it out isn't really a problem as long as the ash is disposed of properly. The DPF is primarily to keep those left-over carbon particles from becoming airborne by burning them before they reach the air. Smog prevention.

A DPF is somewhat fragile (ceramic element), so if it got dropped or thrown on the ground to "loosen up some of that ash", it might be broken now. We've all seen this technique used on engine air filters, which are much more durable. That's why it's so important to have knowledgeable and trustworthy techs working on our vehicles or DIY.

That said, I'm surprised you needed to clean out the ash that early. Most DPF on the big trucks are good for 150K miles to 400K miles before needing service. It seems suspect that maybe the wrong oil was used at some point in the life of the vehicle or the 500 PPM sulfur diesel (the old stuff, aka "offroad" or "farm" diesel) was used for more than just a couple tanks.

This was a good read:

The federally mandated emissions warranty is 8 years/80k miles. Max care coverage on the diesel can go to 8 years/120k miles. There is clearly a potential gap here: owners who log more than 80k but less than 120k miles within 8 years.

Of course, I believe the best solution is DPF deletion, SCR deletion, & PCM tune. In *that* case the emissions equipment truly would not need max care coverage. Heh.
