2015 3500 X long limo RV
I had AEM done on 4 Bluetecs and each 1 of them had such issues. I have a habit that Dennis doesn't appreciate to check the finished jobs.... He found the Freightliner service installed the NoX sensor improperly, and wires dropped on the exhaust pipe and melted. Total cost $250.
On my Bluetec sedan mechanic left huge shipping and part number stickers on new DPF. That qualifies as big fire hazard.
