⚠️ Important: Note for Sound Systems

As you correctly noted, only BOSE systems (typically found in A6/A7/A8) are affected by parameterization loss during firmware updates.

• Since the Audi TT (8S) uses Bang & Olufsen (B&O): You can proceed with the standard update process. The B&O system in the TT platform is not subject to the same parameterization risks as the BOSE systems found in other Audi models.
