No fix for dpf issue?
I have a 2014 pete 330 with a paccar. For the last 4 months I have been fighting this truck to keep running. It spent 1 month at a local shop replacing parts on the after treatment system with no luck. It would drive 20 miles then derate and give the same src codes. Then I took it to peterbilt, they said it needed all the same stuff that was already replaced. They did some computer updates and still no fix. Then it went to cummins who had to run the same tests that the other two shops had already done. They decided to replace the batteries and it worked, so I thought. $8k later and my truck was back on the road. Two months later the same code came back. My warranty is up due to hours on the engine. Truck has 70k on it. The codes are all dpf\scr system related.
Is this a good question?
