I am not the wizard of smart on any of this, but when my DPF failed, I had soot in the exhaust, in my case my tail pipe as I have a weed burner. Check the stacks for soot.... I took the mandate off at that point and got another 70,000 miles out of her, she is in the shop having an in frame at 900,000 miles... Sounds like she is toast...
