Magic number if you exceed 650C? 700C? I think would be safe maximums on pre dpf and pre doc. Pre doc is pretty much the temperature that is coming out of the engine exhaust header and through the turbo.
If it goes higher you can lift off coast, or put it in N to lower egt's. I wonder if the regen would even work with you idling, since its so clogged? No clue, I dont recall if what I read explained much about that

Makes sense, i think they describe it as once it gets to operating temp the regen stays engaged so maybe even while idling which is why the temp can spike higher than normal, any idea how to measure the vaccum on the hose?
