This used OEM Audi inner door seal / weather stripping (part 83A831721B) is a genuine replacement for Audi Q3 models. Also supersedes 83A831721A and 83A831721. Designed for front-left or front-right fitment, it seals the door gap against water, dust, and wind noise. Over time, original seals can crack or compress, causing leaks and cabin drafts. This part fits both the 1.4L and 2.0L turbocharged gasoline engines.
