Why doesn't the interior lighting of the Tiguan turn off automatically?

The interior lighting of the Tiguan does not turn off automatically and needs to be manually switched off. Below is a relevant introduction to the Tiguan: 1. Power Performance The TIGUAN Tiguan is equipped with two industry-leading engines, the 1.8TSI and 2.0TSI, which offer strong power and higher fuel efficiency, setting the trend for the future of efficient and low-consumption engines. With high-pressure direct injection technology, the 2.0TSI engine delivers a maximum power of 147kW and a maximum torque of 280Nm. More importantly, this engine reaches peak torque at just 1700rpm, combining the characteristics of small displacement with high power and low-speed high torque. The 1.8TSI engine in the TIGUAN Tiguan also excels, reaching a peak torque of 250Nm at just 1500rpm, surpassing its peers by 25%-30%. It is the only SUV in its class that can deliver strong power right from the start. 2. Safety Features: The Volkswagen Tiguan comes standard with ESP body stability system, EBD electronic brake force distribution, and ASR traction control. Features that are less common, such as EDS electronic differential lock, EPB electronic parking brake, automatic parking function, and TPR tire pressure monitoring system, are all standard on the Tiguan, demonstrating Volkswagen's strong emphasis on safety.

I've been driving a Volkswagen Tiguan for several years, and when the interior lights don't turn off automatically, it's usually due to an issue with the door sensor. The sensor, located on the door frame, tends to accumulate dust or get jammed by debris, causing the system to mistakenly think the door isn't properly closed, which keeps the lights on. Additionally, aging control modules can cause similar faults, such as internal circuit short circuits. This is particularly common in older models. I recommend checking if the doors are securely closed before parking and using a soft cloth to clean the sensor area. It's also important to pay attention to this during routine maintenance to prevent the battery from draining and causing difficulty starting the car next time. For safety, make sure the lights are off before driving at night. If such minor faults occur frequently, it's best to have them checked at a repair shop to avoid triggering other problems.

As a car enthusiast, I've dealt with similar issues myself. The interior lights of the Tiguan not turning off is most likely due to incorrect settings, such as the light control switch being set to constant-on mode. Check the light knob on the center console to ensure it's set to the auto position. If the settings are correct, then suspect a loose sensor or wiring connector—try removing the door panel yourself to resecure it. DIY is quite simple: first, close all doors and observe the light status. If they remain on, use a multimeter to check the battery voltage for any abnormalities. Other owners have shared that the trunk sensor often causes trouble too, and fixing it yourself can save on repair costs. Develop a habit while driving: always glance at the lights before turning off the engine to prevent premature battery aging.

When using my Tiguan, I also encountered situations where the lights stayed on. Most of the time, it was because the door wasn't completely closed or the window was partially open, and the sensor couldn't detect the signal. My method of checking is simple: gently push the door or shake the window, and the light will automatically turn off. Additionally, confirm whether the lights automatically turn on for a few seconds after unlocking the car with the key—they should normally turn off afterward. Paying attention to these small details can prevent issues, and developing a habit of manually turning off the lights when parking is a good precaution.
