I know that some people might have previously addressed this same concern, but whenever i start my car in the morning (09 MCS R56) it makes an annoying croaking droning sound. This continues for 3-4 minutes and then completely goes away. I dont know if this is Nothing to worry about, somewhat bad, or potentially catastrophic. I do live in the puget sound area WA so it is somewhat cold in the mornings. If someone could shed some light on this i would greatly appreciate it Thanks broskis.
