This 1 1/4" plastic push-in plug was found in my driveway. I suspect it came from underneath my car. I was pulling in to the driveway when I heard a slight sound from underneath the car. When I drive highway speed, I heard a faint slapping noise. I went on line and looked at schematic drawings and was unable to locate it. Car is a 2014 CX-5 GT. Can anyone help me find where this plug goes
