So, what does the new EPA law mean for future Diesels? Will the 2026+ be deleted from the factory?

New laws have come down, putting the brakes on the draconian constraints the EPA has had on Diesel trucks. It sounds like we will be getting pickup trucks that will have fewer emissions equipment on them. No enforcement of emissions equipment, from what I've heard.

That would be great, my truck is one ton so it doesn't have to be tested, but i am told that if you Delete the D.E.F and the SCR system a Dealer will not touch the the truck. But if the EPA changes the rules mine will disappear real quickly :eek:

Take the good with the bad, I guess. a deleted truck is notoriously reliable, and shouldn't need dealership attention. Plus, there are plenty of independent mechanics who would probably do a better, faster, and less expensive fix than a dealership.
As for deleting under warranty, I don't know. I do know most dealerships will cancel a warranty for just about anything. Keep your deleted parts, I guess, in case you decided to change it back, for some reason. Wink wink.
 
It's a funny that in our nearest big cities some 250 miles away over some big, big mountains (still not far enough) they're increasing the smog regulations on diesels...

The changes that I have seen being talked about so far have been a greater tolerance to sensors indicating issues. For instance instead of going into limp mode so fast, there is more time and mileage to get repairs done. I have personally dealt with this one in a rental car in Germany - on a Sunday. Had never heard of limp mode before.

Removing EGR would seem like the biggest gain, but I don't see it on any list so far.
 
They are going to extend the low def warning to 80hrs or 4000 miles . Engine manufactures will also be able to do the same for older trucks . I think it starts with the 2027 year . That is what I read on the website RV travel.com . That is on their Sunday edition , authored by Nancy Dixon .There is also a do it yourself workaround . It doesn’t cancel using DEF you still have to use it but it gets rid of the low def warning until you get around to getting it fixed . At least that is how I read it .

Reread it then keep on dreaming………
 
I saw yesterday the DEF derate mileage changes will go into effect for 2027+ model years AND allow for manufacturers to update existing models if they want. So the question will be if Ram will have a process to update our prior model year vehicles and what they will charge us for that :| Not holding my breath.

If OEMs do not support the change but emissions-compliant tuners incorporated this into their tuning, it would seal the deal for me.

Kory, Nick, Ray - are you listening?
 
I really don't see anything to get all excited about here. In hundreds of thousands of miles I have never let my DEF run out so derating has not been an issue. DEF injector nozzle failure, while a possibility, affects only a small percentage of owners. Increasing the time/miles allowed to get to a repair facility in the event of such a failure is only a stroke of intelligence that can potentially lower the stress level of an already bad situation.
Since we can already drive without fear of derating when the tank is frozen, it seems a small step to increase the distance/time available to correct a "no DEF situation".
 
Feels that way until your one of the small percentage that experiences an issue and your stuck with no way to get off the side of a highway safely while towing something etc. Nothing worse than having an issue thats made worse because of some software constraint putting you and your family at risk.

Would/could buy margin on additional failures:

1) Upstream NOx sensor
2) Downstream NOx sensor
3) DEF Pump (module)
4) DEF quality sensor (module?)
5) DEF heater (module)
6) EGT 4
7) EGT 5
8) DEF level sensor (module)

Any more?

As a DIYer, the ability to continue my trip, get home, get camper parked, and then source a reasonably priced replacement part is a huge advantage over being far from home and being at the mercy of whatever diesel performance shop that has their own bills to pay.

FWIW, I carry a spare DPF injector in the truck, but NOx sensors and module are kinda pricey.

There is nothing to indicated DEF and DPF are going away - that may only be true for Commercial and Farm equipment. All others certain thresholds will be lowered so that people dont get stranded in the middle of no where due to a DEF issue.
