Could be a number of things... NOX sensors could be reading insufficient catalyst conversion efficiency - which could be as simple as replacing the air filter up to requiring the SCR to be replaced. DEF doser could need service, or some component of the DEF system (such as a heater hose) could be faulty. Could be a problem with the DPF... the dash messages are just there to let you know something is amiss... they don't really do anything to diagnose it further, such as give you PID/SID. Maybe try to find another repair shop is about all there is to suggest.

Did the def gauge works ????
KB3MMX Thanks this. -
Yeah, it was showing half.. Little over half. I just got the truck towed to the dealer. They said it will be til Monday night til they check it out. Im just annoyed. Already paid $5100 for a new turbo this week
KB3MMX Thanks this. -
Whats the fault code
-
Not sure, my Driver is figuring it out . But the derate mode was on. Wich sucks because I had no time to drive to dealer. Hopefully it isnt something huge

You won't get a fault code off the dash. Unfortunately, you're kinda at the mercy of the dealership until they can plug in and get the codes.

Ya i figured, They said they will look at it Monday evening so Im renting a car to go back home to La.
-
Unplug the speed sensor at the end of tranny so the timer stop normal and its possible to roll to the shop.

Investing in a ProLink might not be a bad idea. It's not the same as having the proprietary software, but it can give you the PID/SID and perform some command functions across a range of vehicles.
KB3MMX Thanks this.
