I've noticed in the two days that I've had my new Q50 that the engine makes a lot of noise at the initial morning start up. It sounds like the timing chains or valve train making the noise... almost like the oil hasn't circulated to those parts. It lasts for about 10 seconds then you can hear the engine smooth out and it sounds normal. While I know there aren't a lot of owners here yet, I'd like to hear any feedback on wether this is a "normal" issue. Thanks.
