This used genuine OEM Audi Inner Door / Window Slot Seal (4M8839479D) also replaces 4M8839479B. It’s the left rear seal from a donor Q8-chassis model. As a rubber window slot seal, it keeps the glass channel tight against the door frame; a worn or missing seal causes wind noise, water leaks, or whistling at highway speeds. Originally fitted on Audi Q8, RS Q8, and SQ8 with 3.0L V6 (MHEV/PHEV) or 4.0L V8 (MHEV) engines.
