What changes
Module 5F (MIB3): object 0B1B, byte 34, bits 7 and 5 = 1. A driving school mode appears in the MMI menu.
Details
The driving_school menu item from the MIB3 firmware adaptation table; the factory provides this item for the Q3 F3 MIB3. In driving school mode the MMI shows pedal and gear hints; what your software version shows exactly — check after writing. 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. To disable, set the same bits to 0.
