Mein Auto: 2006 550i Sport Package
My '06 550i vibrates a bit at idle. Car idles at 450-550 rpm according to the tach. When below 500 it vibrates. Dealer says that this is the normal idle rpm for the car. I didn't ask if the idle could be raised, but I doubt it. In my case, as the car has over 60k on it, I wonder if new plugs, cleaning the MAF, and perhaps injector cleaning would improve things. I don't know what it was like when new as I just recently made the purchase. I suspect you'll just have to get used to it. Perhaps never coming to a stop is the answer.
