when it starts to fail a regen cycle .. or if Insite is showing an average Inhg rating in the "regen hostory" screen .. on the far right column.. of more than 3.0 inhg when looking down thru the history.

here is another thread where someone posted a pic, that shows what I am referring to...

On a typical a highway truck, the DOC and DPF will usually last about 600k+ miles if you take proper care of them + take proper care of the engine with regular tune-up work, like I describe in my egr-tune up videos.

- Remember.. that it is the ENGINE ITSELF that makes the soot that clogs them up. If they are clogging up too often then it is an ENGINE PROBLEM.. not a dpf problem.
