DEF issue With yellow flashing light and all engine lights on? TRY THIS AND SAVE TIME & Money. 

SCR Harness is worn out causing short circuits and wrong temp values when exposed to high humidity or wet / snow conditions. It goes away because engine and one box heat removes the condensation inside the harness after you reach optimal temps over extended period of drive time

I have the same problem, the truck reduced speed to 55 MPH. I drove for about two hours. then I sopped for fuel did two sets of Regen. And now I lost power completely. I’m now waiting for a tow truck to come take me to the dealership. I’m under a load and two truck is charging $800

Hello. What ended up being the issue?

Hey Desi !! How can I email or reach you ? Can you share business plan steps on opening a truck parking lot ? I watched the video but in so many parts the audio was muffled. 🤍
