What changes
Module 09: object 0A57, byte 7, bit 0 = 1 (0D04, byte 2, bit 1 on a coded module). The coming-home light comes on when the ignition is switched off, not only after flashing the high beam.
Details
The Coming Home trigger in the central electrics: ignition off (terminal 15). Works when Coming Home is enabled in the MMI lighting menu and the switch is at AUTO; the duration is set there too. The map comes in two variants — object 0A57 (module without long coding) or 0D04 (module with a filled long coding); Odyx uses whichever object the module has. Access code 31347; the module accepts changes only with the bonnet open. Rollback: write the object backup from the history.
