I went to my Audi dealership but the guy didn't really help and I didn't have the time over lunch to go back and forth with him. Does anyone have the part number for the fastener that attaches the bottom of the bumper to the belly pan? It has the rubber washer on it so it doesn't scratch the underside of the bumper. I have the S-line bumper if that changes anything. The part he found was $6 a piece, seems high for such a simple part.
