Why can't the light on the roof of the Volkswagen Lavida's cabin be turned off?

The reason why the light on the roof of the Volkswagen Lavida's cabin cannot be turned off is that the constant-on mode is activated. Modes of the interior dome light: Generally, there will be buttons next to the interior dome light, which usually have three modes: ON (constant-on mode), DOOR (lights on when the door is open and off when the door is closed), and OFF (off mode). When the button is set to DOOR, the light will automatically turn on when the door is opened and turn off when the door is closed. Switch for the interior dome light: Generally, the interior dome light not only has a mode selection switch but also a separate switch. Some cars' interior dome lights can be pressed down to turn on or off, a feature that many car owners are unaware of. You can try it to see if your car has this function.
I encountered the same issue last time when driving my Lavida. The dome light not turning off is usually caused by a stuck door control switch. The Lavida's dome light has three modes: on when doors open, manual switch, and always off. If you set it to the 'on when doors open' mode but it won't turn off, there's an 80% chance the door isn't fully closed or the door lock sensor is stuck. Get down and listen for a clicking sound from the door lock, or press the door latch a few times to reset it. Electrical circuit issues are less likely, but it's also important to check if the dome light switch contacts are making poor connection. A poorly closed trunk lid can also affect this - that's just how this car is designed. If all else fails, visit a 4S shop and have them read the body control module data with their computer - it might be signal confusion caused by a wiring short circuit.
