⚠️ Important: Note for BOSE Sound System Owners

If your Audi is equipped with a BOSE sound system, please be aware that a standard firmware update will NOT solve Bose-specific acoustic problems and may cause the amplifier to lose its specific tuning (parameterization).

• Expert Recommendation: We strongly advise using the “User-Defined” update mode (via the Green Menu) to exclude the BOSE amplifier (AMP) from the update process.
• This prevents sound quality loss or the “no sound” bug, which requires specialized tools (VCP/ODIS) to fix.
