A little annoyed to have to be posting this but it appears my 3 day old X1 is going to need its first trip back to the dealer. Has anyone had a grinding or vibrating sound come from the front passenger side when your slowing down or idling in traffic or a red light? It seems to be when the car is warmed up or the AC is on for a bit and it sounds like it's coming from a fan sort of behind the passenger side headlight. As soon as you start accelerating again it goes away and then comes back when slowing down and then at idle. I've found if I don't drive aggressively at all and don't turn the AC on I can drive for at least 10 minutes without it happening. Turning on the AC appears to make it do it within a few minutes.
