Probably heat shielding and may indicate a motor mount getting sloppy.

Porsche used cheap-*ss sheet metal screws to hold the alloy heat shielding together. After time, especially if they've ever been loosened and re-tightened, the holes in the alloy shields expand and the sheet metal screws can no longer hold it tight.

The fix is to get small gauge SS machine screws with a nut and lock washer. You could try larger sheet metal screws, but you'd be right back in the same boat in 6 mos. to a year.
