- π§ Second generation (A5): The tag is moved down to the crankcase, requiring the use of a mirror or lift for visual control.
- π§ Third generation (A7) and A8: The location depends on the type of drive; in all-wheel drives, access is complicated by a transfer case and driveshaft.
- A4 (1996-2010)
- A5 (2004-2013)
- A7 (2013-2020)
