Why can't the trunk of the old Touareg open?

[VonPaul]

The trunk of the old Touareg may not open due to a broken switch, wiring issues, or mechanical parts being stuck. External opening method: To open the trunk from the outside, simply press and hold the trunk button on the key fob, which is very convenient. Mechanical key opening: Insert the key into the tailgate lock to open or close the tailgate. This is the mechanical method and dates back to the era when car tailgates first appeared with mechanical keys. Sensor-based opening: Many high-end models are equipped with a sensor-based trunk. The design of the sensor-based trunk opening is to allow opening the trunk without touching any buttons when carrying items. As long as the car can detect the key, simply sweep your foot under the rear bumper sensor, and the trunk lid will automatically open. To close it, gently sweep your leg under the trunk sensor.
