On the 805N today, cruising in 3rd in the stop-and-go traffic when suddenly it feels like I hit something. I look around and see nothing near me, and notice it does the same thing again a few more times, each time it does the indicators both flash at the same time. Now I get the "engine malfunction" warning on the i-drive screen. I try up-shifting to keep the revs as low as possible, but it still continues to jerk / sputter violently. Keep in mine I have 9k miles on this N55, and have had the Procede V5 on it for the past 4k-5k miles or so.
Any ideas before I go to the dealer and they claim that my mods caused the issue?
