Is this normal with the X3 or not? I am 100+ miles from dealer and headed back next week to check on a few things with this new vehicle, and wondering if I need to add that to the list, or just get more educated on what is normal for this vehicle.

Thx,

Cold exhaust rattles are not normal. Have your dealer check it out.
