This used Audi exterior B pillar screw cap/cover (OEM 4M8853590) is a genuine right-side trim piece that snaps over the B-pillar screw, restoring a clean factory appearance. Also called a screw cap or cover, it serves no mechanical function—just cosmetic coverage for the fastener opening. Originally found on Audi Q8, RS Q8, and SQ8 models, this cap blends with the pillar and helps prevent debris from collecting around the screw head.
