When the interior light of a Volkswagen car stays on, it is in the ON mode. You can turn off the light by switching the mode to OFF, or it might be in the DOOR mode, in which case the interior light will turn off after the car doors are properly closed. Volkswagen is an automobile manufacturing company headquartered in Wolfsburg, Germany, founded by Ferdinand Porsche. The company owns brands such as Audi and Volkswagen. Volkswagen's models include Jetta, Golf, T-Roc, Volkswagen CC, and Magotan. Taking the Volkswagen T-Roc as an example: its front suspension is a MacPherson independent suspension, and the rear suspension is a multi-link independent suspension. It is equipped with a 1.4T turbocharged engine, with a maximum horsepower of 150 PS and a maximum torque of 250 Nm, paired with a 7-speed dual-clutch transmission.

It's a fairly common issue for the interior lights of Volkswagen cars to stay on constantly. I experienced this myself when driving an old Bora, and it was quite annoying. I suspect it might be due to doors not being closed properly, faulty door locks or door sensors causing detection failures, or incorrect timer settings preventing the lights from turning off. First, try opening and closing the doors several times, then check the light switch position on the center console. Some cars have an automatic setting—switch it to manual 'off' to see if that works. If the problem persists, try turning off the engine and waiting a few minutes before restarting the system to see if it resets. If the lights remain on and drain the battery, be cautious of battery depletion—it's best to manually turn off the lights when parked to avoid trouble. If all else fails, visit a 4S shop or a professional repair shop to check the wiring and control unit. Remember, don’t underestimate this issue—overly bright interior lights at night can distract you and compromise driving safety. Regularly checking the interior lighting condition can prevent many faults, saving you both money and hassle.

This issue is most likely caused by an incompletely closed door or sensor malfunction leading to control failure. I recommend starting with simple checks on the switches near the door frame - sometimes dust or wear can cause signal interference, resulting in the light staying on. The position setting also matters; for example, if the dome light switch is set to always-on mode, it won't turn off - try switching it to the off position and observe any changes. If that doesn't work, there might be a wiring short circuit or aging control module requiring part replacement. Leaving lights on continuously drains the battery quickly, potentially causing starting difficulties or even breakdowns, which is unsafe - address this promptly. If all else fails, take the vehicle to a nearby repair shop for diagnostic tool inspection - repairs aren't expensive, and DIY attempts might damage other components. Develop a habit of checking lights before driving to ensure everything's normal and prevent potential hazards.
