What changes
Module 5F (MIB3): object 0559, byte 0 = 0x45 (Europe). Station logos come from the European database.
Details
Regional identifier of the station logo database — needed on cars from China and other regions. Not a tuner conversion: bands and tuning step stay. The same map as on the A3 8Y, where it is verified by a write. MIB3 only (from model year 2021): the MIB2+ (MH2p, 2019–2020) has no such object, and Odyx refuses before writing. If module 5F is SFD-protected (Q3 F3 from model year 2021), Odyx asks for a token; some Chinese MIB3 units have no SFD — then no token is needed. The MMI restarts after writing. Rollback: write the object backup from the history.
