The Audi A3 was introduced in 2005 as a compact luxury automobile built by Audi since 1996. Its size places it somewhere between a 5-door sedan hatchback and a conventional wagon, and it uses the Volkswagen A platform shared with the VW Golf, Škoda Octavia and SEAT León. With stress placed on sportiness moreso than cargo capacity, the A3 is aimed at drivers interested in performance who also might appreciate a bit of extra space for their active lifestyles. There is no onboard programming available for keyless entry remote fob smart keys, meaning you will need to have special equipment to program a keyless entry remote fob smart key for your Audi A3.
