The Audi A3's driver-side floor uses a pair of round factory retention posts rather than the twist-lock cams found on some other VW-group cars, so check the retention type on a universal mat. The Sportback and the Saloon share the 8Y front footwell, so front mats fit both, and the rear mats are shared as well.
