Audi OEM Stone Guard, part number 8W0505561B, is a used genuine left-rear stone guard sourced from a donor vehicle. This part supersedes the earlier 8W0505561A. It serves as a protective shield behind the left-rear wheel, deflecting debris and road grit from the underbody and adjacent components. When this guard is missing or damaged, you may notice increased road noise or exposed wiring and hoses in the rear wheel well. It fits Audi A4, A5, Q5, and S/RS models equipped with 2.0L four-cylinder or 2.9L/3.0L V6 engines.
