Any updates? I'm asking because my 2015 LS XR4046H with 260 hours has a dpf issue specifically the burner injectors which run 2k for just 2 injectors.I will update this thread. I have had issues with my dpf at 16 hours it was replaced then again at 67 hours and thay did an update and now have 700 hours on it and I believe it's starting to be an issue again. I have one of the faulty ones that I plan to gut and try to use for the dpf delete.
