What changes
Unit 09, object 0A64: byte 3, bit 0 = 1. The lighting of the buttons and switches in the cabin fades in smoothly instead of switching on at once.
Details
Setting of the newer MQB body control module. It affects the button lighting; a smooth fade of the cabin dome lights is a separate setting with no known map. On the older module the same option is object 0D03, byte 1, bit 3; a3c first checks that the unit 09 long coding is empty, as on the newer module. Unit 09 on MQB Evo is SFD-protected — a token for unit 09 is needed. Roll back by writing the object backup from history.
