Well my truck is stuck in def limp mode and it wants me to take it to the dealer. I pulled apart my def tank, cleaned everything, and put it back together. I cleared the codes and the check engine light went away. It's still stuck in limp mode and will not drive over 5 mph. Very frustrating! Any help is much appreciated.20190614_203842.jpg
How many miles are on it? As stated below, you’ll probably need to see a dealer, to my knowledge it’s either electrical or the injector is malfunctioning but I could be wrong.

Try pulling the battery cables for 15 min. Short of that, all sources point towards needing to see the dealer for this.
What year of truck, how many miles on truck? did the truck throw the code on its own? or was the def tank low or empty?

Thank y'all for the kind responses. It's a 2015 3500 with 103600. Fresh out of warranty and ready for a delete. My only issue is that I need to drive my truck to Austin on Tuesday so this has to get fixed! The tank was low when I got a warning. I pulled the tank apart and cleaned it. I pulled the injector and cleaned it. I had the batteries disconnected for about 30 min. I cleared the codes and the check engine light went away and no codes returned. But it's still stuck in limp mode! I guess it will go to dealer on a flat bed ...
so you go a warning telling you DEF was low or out of def? not sure on your year but the newer ones there are a few warnings you get before you get put in limp mode. did you get those? so on only tanks that have never been cleaned and have higher miles. the tanks do crystalize over time. Have seen bottoms of the tanks glazed over bad enough that you now have lost some capacity. now that I know this info , if you let me know if it went into limp mode without prior low DEF warning . I will reach out to a bud and see if I can find a DIY reset. or if a scan tool is needed.

It was a repair warning that popped up before the tank was empty. I've gotten the low def warnings several times, but this one specifically tells you to take it to the dealer and honestly I have no idea why I got the warning.Originally Posted by DIESELWRKS
My truck has 103600 mi and the tank was spotless!
The only thing is the injector has some crusty def buildup. Instead of going to the stealer, I placed an order with DRD

Did DRD tuning fix your limp mode?
