Performing firmware update of the B&O external amplifier in Audi S3 (8V) equipped with MMI MIB2 (MHI2). Previously I've updated my Audi MMI system but skipped the amplifier update to avoid any potential issues then. Not is time to bring the amp to the latest version.

⚠️ Bose sound system will most likely require parameterisation with VCP or ODIS. If you want to update Bose external amplifier, make sure that you have proper dataset to upload afterwards. Other systems used by VWAG (Dynaudio, Fender, Burmester, Canton, Beats) are apparently not requiring dataset upload after firmware update.
