What is the name of the screw

[Andrebolo]

Hi I’ve had my gti for about a year now and I’ve had no problems with it but today I got home and found a screw on my driveway where my car was parked I don’t know where it came from or what sort of screw it is, when I’m driving I can hear a rattling noise come from the front of the car any help would be appreciated

Security torx screw, I can not remember seeing one like that used on a MK5. Gert it on a lift and find the source of the rattle.
