Cold Start
I've noticed when the car sits overnight during part of the cold start cycle the engine idle gets a bit "lumpy" which kind of shakes the car a bit every few seconds or so then after a minute or two it idles very smoothly; is this normal with the 55?
Thanks

Thanks for all the feedback.
The reason I noticed this is I always let my cars idle down after a cold start before driving off; I've just never had one shake it up like this before. I also haven't heard of this problem with 2006 500's, 350's etc; maybe it's a 55 thing? If it is a 55 thing should n't MB provide a flash update for the ECU. Aren't cars allowed to run richer during the cold start cycle?
