Tech. question

[wheels1]

I put a deposit on a Velar 3L d HSE 2020 and it was along way from me so they were going to deliver it. After studying the photos I noticed the disc on the bottom grill was missing and it seems to be on all other HSE Velars I have seen. does anyone know what it is ? I think its for the radar which the car should have and the only reason I can think of it is missing is maybe it has been in a shunt and not put back.
Please can anyone help? The photo is of another car not the one in question.

Thanks. way to big for parking sensor. No point posting photo of car as it is not there. Pulled out of buying it now as I was unsure if had been crashed.
