Thinking if it is higher mileage and regeneration isn't successful you probably have to replace the DPF.
I'm surprised you can't make an adapter you could bolt onto the end of a good sized Kerosene Torpedo heater with the cone removed and torch the Sh@t out of them DPF turds real thoroughly and reinstall afterwards after cooled down.
