Why doesn't the Volkswagen cabin light turn off?

[Foster]

The light on the cabin ceiling won't turn off, possibly because the constant-on mode is activated. Introduction to buttons near the cabin ceiling light: There are usually buttons next to the cabin ceiling light with three modes: ON (constant-on mode), DOOR (lights on when door opens/off when closed), and OFF (off mode). Normally set to DOOR mode, the light automatically turns on when opening doors and off when closing. If set to ON, the light remains constantly on and requires manual shutoff. Abnormal interior lighting: If interior lights stay on abnormally, check the light switch, doors, and lights themselves. Since interior lights are frequently used, most cabin lighting systems rarely develop issues.
