I just bought an '08 with just over 22k on the clock. Taking it back in to have the radiator replaced tomorrow under warranty (they say it's leaking, haven't seen it leak yet, lol). Anyway, I've had it go into what I assume is regen mode three times this week. Seems like every couple days when I pull up somewhere and put it in park, the RPM's jump up to about 800-900 and stay there for a few mins and then idle back down. I have no indication on the dash of a regen cycle. Does anyone know of the most recent flash for this thing so I can ask for it by name?
