Genuine OEM Audi Seal, part number 8F0871632A. This seal is designed to provide a weather-tight barrier within the convertible roof assembly, preventing moisture and wind noise from entering the cabin. It is positioned along the roof frame structure as illustrated in the diagram. Manufactured from high-grade, flexible rubber, it maintains its shape and sealing properties across a wide range of temperatures. Genuine OEM seals are critical for convertible systems to ensure the exact contour and compression required for a leak-free seal against the body panels.
