HELP! Message center: Speed limited to 50mph Exhaust fluid system fault???

[darkshadowgray08]

Supposed to go on a 200 mile round trip tomorrow, and just got this message tonight on the way home? It says it will limit speed in 46 Miles?? Truck has 1100 miles, WTF??? I was also getting pretty low MPG's compared to what everyone told me i should expect, i realize it is no where near broke in yet, but 14mpgs?

My spartan tuned 6.4L is starting to look better all the time! Anyone had this happen before??

Did you check the message cluster for the DEF Level being Low?

Yep, 2012 6.7L. I checked for warnings, and it says nothing about def being low. This is the first and only message. They told me when i picked it up that it was full of def and fuel, and that i should not need to refill for 4-5,000 miles at least.

Sounds like a problem with the DEF system. If it thinks its empty it will go into a limp home mode. Not sure if that's whats going on here but you should have it checked... and pray that you didn't get water in the fuel somehow.

Take it to your dealer. I had that issues when I had a faulty NOx sensor. They should beable to clear the message for the time being

Maybe add DEF?????????????????????????

When I bought my 6.7L it only had 2 Gallons of Def in the tank. This maybe your situation as well?

There is supposed to be a series of warnings about low def up to that point, i am pretty sure if that was the case, we would have gotten a low def warning along time ago. This is the first and only warning we have gotten since new.

We will be taking the trusty f150 today instead, but sure is frustrating to spend so much money on a truck, and 1100 miles later have to take it to the dealer!!! I sure hope this is not a sign of what is to come, or i will be kicking myself for getting rid of my 6.4!

Dropped truck off at dealership first thing this morning and picked it back up this evening. They didn't have the paperwork ready, so i don't know exactly what they did, but they said it was a programming glitch. They said they reflashed it, and did a road test, and supposedly that fixed it...time will tell. I hope this isn't like the 6.0 reflashes i got every other week when i had my 03 that were the magical cure all, but never did make it run properly.

For kicks, i stopped by the local Flying J and topped off fuel and the DEF tank, and it only held 1.5 gallons, so it was definately not due to low DEF level! By the way, your local truck stop is definately the way to go for DEF, i payed 2.79/gal, as opposed to $7-10/gal for it in a jug at auto parts store!!

Hopefully this is the end to my problems, otherwise i will be greatly regretting getting ready of my 6.4!

Just cut the DPF and UREA off and never worry about it again.
