Since the light stays on, it should be a switch issue. You can check if the switch is set to the always-on position and readjust it. If it still doesn't work, you can call the manufacturer. Besides the switch problem, there could also be an issue with the wiring, so you can inspect the wiring. Relevant introduction about the Tiguan is as follows: 1. Exterior: The rounded and full design is a classic of the previous generation Volkswagen family design. Years of strong sales have demonstrated its impressive capabilities. Even now, the Tiguan's exterior still doesn't look outdated, and compared to the upcoming new model, it has a more practical feel. 2. Interior: The interior of the Tiguan is consistent with its exterior style, featuring no novel designs but emphasizing simplicity and practicality. Although the unchanging design might seem a bit dull, the Tiguan still delivers a good experience with its excellent craftsmanship. 3. Features: The Tiguan Silk Road Edition 300TSI model comes with features such as a panoramic sunroof, leather seats, xenon headlights, Vienna genuine leather seats, dual-zone automatic climate control, self-detecting digital reverse radar, cruise control, electrically adjustable and heated exterior mirrors, automatic wipers, 12-way power-adjustable driver's seat, rear parking sensors, six airbags, electronic parking brake with Autohold, and more. 4. Powertrain: It is equipped with a 1.8T engine, delivering a maximum power of 118kW and a maximum torque of 250Nm, paired with a 6-speed automatic transmission. The drive system is front-wheel drive, and there is no four-wheel-drive version available.
I've been driving a Tiguan for several years and have encountered the annoying issue of interior lights not turning off a few times. Common causes include faulty door switches or sensors, such as a rear door not closing properly or corroded contacts, which can trick the system into thinking a door is open, keeping the lights on. It could also be the light knob left in manual mode or a failing control module. A quick DIY check involves ensuring all doors are fully closed and testing by pulling the fuse (usually located near the glove box) to see if the lights go off. I once fixed it by sanding the contacts, but with today's more complex electronics, it's safer to avoid DIY fixes and have a professional diagnose it with proper tools. Also, constant light use drains the battery, shortening its lifespan, so a quick pre-drive check can save a lot of hassle.
I'm someone who loves delving into minor car issues. There are quite a few reasons why the interior lights in a Tiguan won't turn off, but don't panic just yet. The most common cause is a stuck or dirty door sensor, which tricks the light into thinking the door is always open. You can clean the small button in the door gap with a cotton swab dipped in alcohol. It could also be a blown fuse or poor switch contact. Volkswagen models have both manual and automatic modes, so check if the interior settings are in the wrong position. If the light stays on and drains the battery, it can be particularly troublesome in winter when the battery is weaker. I recommend trying a system reboot: disconnect the negative terminal of the battery for a few minutes and then reconnect it. This often works, but be careful not to cause a short circuit. If all else fails, it's best to have a mechanic look at it sooner rather than later, as driving with malfunctioning lights can be distracting and unsafe.
