I just got a 2018 LR discovery, certified pre-owned, today I took it to the car wash and a litter later opened the passenger side door and this chip attached to an electrical strip fell off, does anyone know what this is related to, before I go back to the dealer?

 

its from the back rear side window, for defrost or antenna. It comes out of the top of the window and clicks into a button -style connector on the window.
Not sure if its on both sides.

 

Thanks for the reply, I just had the front windscreen replaced, could it be from that?
