My steering column cover does this. Drove me nuts for months. One day it was doing it, I put my hand on the cover, and it was quiet.
I know people that work as NVH engineers that spend their careers looking for BSR (Buzz, Squeak, Rattle). So, this is a big problem. You really need to have a second person move around the cabin while you are driving looking for these noises. This is dangerous, so do it at your own risk.
