Hi. New to this forum so I’m looking for some guidance for this code that keeps popping up. After reading a few I see that it’s an emissions issue. I have a 2014 JGC eco diesel and my scanner will not delete code. (Says it’s permanent) It seems to come on for a bit then decided to go off. Has been doing this for several months. One time the dealership said the had to do a regen. Worked for a bit. Now it’s a sensor which is costly. I have 76k miles in car. I was in the settlement for emissions so dealership did what they were “required to do” to fix but still light comes on and stays on. About 10 months ago I had to replace the EGR cooler valve which set me back $5200 Help. Need some suggestions. I’m about ready to trade this car in!!!
