Hello, I have a 2014 D5 with 4660 hours on it. My yellow def light is staying on and the red alert sign is flashing only when the turbo is de rated, once it stops beeping the turbo is restored. It is regening and randomly blowing black/brown debris from the exhaust pipe. It runs fine and pushes fine, how long do the DPF filters last? Should it be changed at a certain engine hour? I did change the dpf sensor and it started regening with the dark brown exhaust , ran it for 12 hours, is this an indication it is working correctly and finally clean itself? Thanks, Gary
