This Audi side skirt rocker cover mount bracket (OEM 4B0853921B) is a used genuine part, also superseding 4B0853921A and 4B0853921. Located on the front left, it secures the lower rocker panel to the body. Over time, these brackets can corrode or break, causing a loose or misaligned side skirt. Fits Audi A6 and A6 Quattro with 2.7L, 2.8L, and 3.0L V6 engines.
