What are my options there. DEF gauge reads about 1/2 right now. I take it out once every 3-4 weeks just to keep the batteries up, etc. Really won’t be using it much til late April or early May.
Best advice I could give would be to only put enough DEF in it to satisfy the amount of use you plan to get out of the truck in a given timeframe. When it goes into storage or sits for a long time, make sure the DEF that gets put in the tank is as new as possible. Preferably by checking the date codes on the 2.5 gallon jugs. Theoretically DEF has a two year shelf life under the most ideal storage conditions, however most real world practical applications are far from ideal. You should be able to make it last a year as long as it’s not seeing substantial heat or cold. I’d run it down to about 1/4 or so and then add some fresh stuff if it’s going to sit a while.
Sounds good thanks for the info. Truck sits in my shop out of the cold and sunlight when not in use. DEF was last added early fall before hunting season. Should be good to go til April/May when towing season starts up for me.
If in doubt, you could always draw out a small amount of the fluid in the tank and run it through a refractometer. There are several inexpensive ones available online. That would at least let you know where the fluid stands before you run the truck. The downside to the current system is that there is no easy way to drain the tank if the fluid inside is going south. Have to pull the bottom of the tank and drain it the hard way.
How much is “a lot” of city driving?
In one case, it was probably 100% stop and go and it regened after 130 miles. Another case was prob 75% stop/go and it happened after 175.
To clarify further… prior to the new DPF, it didn’t matter how I drove. If unloaded it would regen every 30-100 miles (even when mostly highway).
Have you gotten the buy back information back from FCA yet? We have had our 2022 Ram in multiple times for regen issues and will be taking it back again next Thursday. They updated software and replaced a sensor that was a recall and did have a Star report open in the past. Here we are again with our truck constantly regen about every 75-100 miles or so. We have a little over 30,000 miles on ours we drive it a lot and also haul farm equipment nothing too heavy throughout the year and also have a dump trailer we haul stuff with quite often. Just curious where I should start. How do I contact FCA?
The arbitration info should be in your owners manual/packet. I went through that process with a Ford 3/4 ton a few years back. Worked out great.
Sorry for the late response, FCA basically told me to pound sand because I didn’t have enough repair attempts (6) or enough days without my vehicle (119). I went to a new dealer and they installed a new DPF and temp sensor. The issue sort of went away, as in it only regens every 150ish miles now instead of constant, but just the other day I got a message on the dash saying exhaust system requires repair see dealer. Light went off before I got to the dealer and they said they couldn’t do anything for me without the light being on, so that night I submitted all the documents for a lemon law claim. I haven’t heard anything back from that yet. As for the FCA contact info I just googled mopar buyback and all the info was on their website. I’d link to it but I’m on mobile and running around right now. I think I linked to it in a previous comment though.
150 miles between regenerations is far from fixed.
There’s multiple solutions to the issue. It depends on which part (or parts) of the system are malfunctioning. There’s a laundry list of systems that have to be inspected in order to determine what’s causing the frequent regen issue.
Thanks, I think I'm gonna start with the air filter
