Audi Ambient Lighting Coding. Cant figure out how to change the speaker lighting. Light colors can be controlled by original knob.
That one should be documented in Long Coding Helper. Enable LEDs remain bright for parking lights. Select byte 16 4.
32 colors ambient light for options.
Enable Ambient Interior Lighting Control. Select byte 16 4. Light colors can be controlled by original knob. I think the other bit enables Personalization of Ambient Lighting via MMI Car Menu but this is less.
