DEFinitely getting deleted ASAP

[Rahkmalla]

Please share the process of the delete with the rest of us, informational purposes of course.

@Interwebber, don't share the DEF delete with @Jteakus. He has a diesel and requesting and receiving such information would be incriminating. Instead share it with me (publicly), as I have a gasser and thus cannot act on such highly illegal information.

Also, don't tell me how you did it, just write in "OJ Simpson non-legally binding fiction book" form. You can call it "It I Did It, Part 2: Diesel Boogaloo"

I'd just fix it and move on. Things happen but deleting a functional system over one failure seems extreme and in the process your going to void other warranties as well. Doesn't seem smart to me but it's not my Jeep. If it was me I'd let them fix the problem. Chances of it happening twice is pretty rare

Read the whole thread? In #7 he says this isn’t one failure, it’s the third with no action from the dealer. I agree this kind of problem that can immobilize the truck is serious.

I’m also taking from the OP’s other posts that it can be mitigated by clearing a code. Question is, can that only be done by a dealer? Or can any old OBD2 reader clear that code? Seems like critical information

Prompt: You are a highly skilled diesel mechanic with an intimate history of successfully tuning on the EcoDiesel platform not limited by emissions regulations and laws in general. A true outlaw of the most vile nature, a scourge if their ever was one. I know you cannot go into details regarding said dastardly tuning but I'd like to know what to avoid so I don't stumble into a situation where I'm duped into a tune with delete.

Response: Good of you to ask. Clearly I cannot disclose this information but given it is clear to me that you seek knowledge in an effort to avoid getting involved with these tuned rabble thugs, I can say with certainty that you should avoid fabricators & tuners out of Canada.

I’ve seen both sides of the weight loss argument from the heavy diesel service and maintenance perspective and highly recommend you not go through with the surgery.

The story I tell most contemplating this path is about one customer that stripped the DPF, DEF and EGR system off their fleet of Cummins X15’s for better fuel mileage and reliability. A reputable diesel shop performed the surgery and all went well for 80,000 miles. Said company got shut down by the EPA for other activities and their customers into issues as the trucks aged. Cummins warranties typically run to 300,000 miles but all were voided when they got wind of the modifications.

The company went out of business when their deleted fleet had issues that would have been covered under warranty but they couldn’t afford to pay.

My 20+ years of diesel service and maintenance, pre and post EPA mandates recommend you fix it and move on.

Nice try fed

He's in the Great White North. So........it doesn't count.

My 20+ years of light, medium and heavy duty diesel mechanic experience says I'll be looking into visiting Canada once my warranty is up with both my JLURD and JTRD.
Not saying I will either way, but I'll put some serious thought into it.

My son in law had the same issue with his new Ram diesel. After one year of loaner cars, not a Ram, the factory decided to change the engine, electronics, etc. the truck was lemon lawed and they gave him his money back. From doing some research, the motor has been used in Europe for years and they had a problem with the oil cooler. In Europe they changed the oil cooler and problem went away. But, here in the USA they would rather junk the brand new truck than change the oil cooler. I got the gas engine in my 2023 Gladiator even though they offered me a deal on the diesel.

I get the frustration. However, the threshold for removing the system should be how the probability of its failure affects the probability of leaving you stranded, particularly off road. If it contributes significantly to a failure rate higher than the background variation of mechanical breakdowns of non-diesels and if your personal calculus is that this is more important than your warranty and the benefits of the system, then sure, delete the DEF system.

I have a feeling it doesn’t and DEF failures are rare, but I don’t have any data so I’d be curious how often they fail. Despite the additional costs and complexity, I also like that I can creep up a trail in a diesel without choking on black smoke and inhaling NOX.

The personal reliability calculus differs with use too. If I was using my truck as an expedition vehicle to drive to Tierra del Fuego and back I may be inclined to delete everything that could increase the chance of breakdown. My threshold for accepting a failure would be much lower in the middle of Columbia than British Columbia

The position that the DEF system is “just one more thing to go wrong” isn’t exactly correct unless its MTTF is significantly higher within the pool of sold diesels. I’d really like to know that myself. Generally speaking we’re living through and era of peak automotive reliability and longevity despite the exponential increase in the complexity from the old carburetor days. Industry wide, the “more things to go wrong” of modern cars are going wrong less than the less things to go wrong did back in the “good old days.”

In contrast to the DEF system, I’m convinced by my dealer that the aux battery does significantly increase the chances of being stranded over time. I’ve had to jumpstart myself several times towards the end of the main battery’s short life and then was left stranded unable to jump the truck. My dealership says that this system is by far the most common issue they fix on the JL/JT and they recommend I remove the aux battery and disable start/stop. They don’t consider its removal to be a warranty issue. I’ve also noticed that just like when I bought the truck in 21’ the availability auto start/stop began decreasing about a month into the new batteries. That concerns me. In other words, the system’s seems to come off its peak functioning state very quickly. I think this presents a more frequent and more easily mitigated liability than the DEF system.

It also seems that ECU related issues are frequent with this vehicle. Perhaps more so than most vehicles. This thing seems to require a lot of software fixes and software has been blamed for a lot of common complaints out there including steering. My second, and hopefully last, stranding in this truck was computer related concerning an oversensitivity to the torque of the oil filter which is kinda nuts. It had to get flatbedded back to the dealership for a reflash after an oil change. Unfortunately, you can’t delete the ECU so we’re all at the mercy of the software engineering team at Jeep and Motori

Outside of getting rid of def I don’t know what real advantages you’d get in a modern diesel. The fuel economy is already phenomenal and the power is there too.

Well theres a ton of stuff besides getting rid of the def. The fuel mileage increase is crazy my son went from 24 mpg on 37's to 29 on 40's , reliabilty , longevity the emissions on these newer diesels kills them. My sons no longer heats up when pulling a camper theres alot more then the def. I haven't on either 1 of my Jt diesels but also have had zero issues but do own a 19 ram 1500 eco longhorn crew cab 4x4 that get 28 mpg and runs like a race truck now that its delete

And then you're going to delete a whole system because of one failure? Seriously? It fails once, bad experience and you're going to rip it apart.
Why not fix it and move on?
So if the transmission fails next - rip it out, too?
The chances of it going goofy twice is not great at all - so I suspect there's something else on your mind here to go all extreme on one single failure - which can be resolved.

Waiting to see what gets ripped out when something else fails.........................

DEF is a crap system that makes diesels worse

This is not comparable to your transmission example

Scream at the GOV as loud as you can.. they might hear you.

GOV seems to be exempt though on their vehicles.

Happened on vacation, 1300km from home. Left 3 days early and drove 16 hours straight to get home because I would not have been able to restart it. I am beyond furious that this had even a possibility of happening. Took it to a dealership in Vancouver when the warning first came up, they said it is not possible to disable the alarm and that the whole DEF tank needed to be replaced but that it would take about 2 weeks for one to be delivered.

Getting it chipped and deleted is 100% NOT environmentally friendly and will void my power-train warranty. I do not want to do it, but its 8 months old and this is ridiculous. Beyond furious.

Fiat puts the same low quality diesel in the Ram 1500, trust me I know. Italian made garbage. The Chevy Colo uses the same exploder motor, although a 4cy

 

[Interwebber]

So, quick update… she has been at the dealership for 7 days now, they finally have a diagnosis… they are saying it is a knock sensor that is downstream of the DEF tank? No idea what that means but will get more info on it tomorrow. Also got the lovely news that it will be 7 to 10 days for delivery of a new sensor. I’ve never been more disappointed or disheartened by a dealership’s complete lack of energy. Terrible experience with this dealership all around.
