Anyone experience a metal clinging noise?

Lately, I have been hearing a noise that sounded like metal clinging on each other. It comes from the driver side lower seat belt mount. It doesn't happen all the time, but when it does, it's somewhat annoying. The passenger side is perfectly fine. I'm probably taking it into the dealer this weekend, but I wanted to see if anyone has experienced this before.

First year B8 S4 and E92 335i, you must really love spending time at the dealers. Anyways can you write a mini review comparing the two cars? It would be nice to get a non-biased review.
