How to reset the airbag warning light on a Tiguan?

First, remove the car key and disconnect the negative terminal of the battery. Wait for 5-10 minutes, then check if the warning light is still on. If it's off, it was a false error. If the light remains on, use a professional diagnostic scanner to clear the fault code and try again. If a connector in the airbag system is disconnected or severely discharged, this is also a common fault. Check the connection of each connector (yellow connectors), reconnect them, and it's best to secure the connectors with a layer of black tape.
That time my Tiguan's airbag warning light came on, which gave me quite a scare. I pulled over and tried restarting the engine several times, but the light remained on. Then I checked the fuse box under the dashboard and found the airbag fuse had blown, so I quickly replaced it with a new one to test. After replacement, the light went off, but I suspected it might not just be a fuse issue – things like loose sensors under the seats or wiring could also trigger the light. To be safe, I later took it to the dealership where they ran a computer diagnosis and confirmed no problems, recommending regular wiring maintenance. In short, when DIY is possible, start by checking fuses, but since airbags are safety-critical, don't take risks if unsure – better seek professional help.
