What is this weird plastic electronic module in BMW F10?

[gabed]

Hi,
I was lately disassembling my center console - or changing it out rather on my BMW F10 2013.
I have noticed that there was a little electronic device with a cable input on the side. It was flat and rectangular. Grey in color and not very heavy.

One in the rear vent and one on the front inside the center console. Does anyone have an idea what these might be or what do they do?

Cheers
