Where is the fuel tank cap switch on Volkswagen cars?

[Gwen]

The fuel tank cap switch on Volkswagen cars is located on the right rear side of the vehicle. Generally, there are three main ways to open the fuel tank cap, which are: 1. Push-to-open type. This is the simplest method, where you directly press the fuel tank cap with your hand when the car is unlocked, and the cap will open. Note that the fuel tank can only be opened when the car is unlocked; it cannot be opened when the car is locked. This method is more common in German and American cars. 2. Switch button type. This type of fuel tank cap is controlled by a switch button inside the car. The location of this switch varies depending on the car model. In general, for economy cars, the switch is located on the floor to the left of the driver's seat. In more upscale models, this switch is designed as an electronic button, placed on the left front door panel or the center console, marked with a fuel pump icon, which can be easily found with a little attention. This design is commonly used in Japanese and Korean car models. 3. Mechanical key type. This method is becoming increasingly unpopular, as using a key to open the fuel tank cap is somewhat cumbersome. This method involves directly using a key to unlock the cap. This design was more common in older American and French cars and is now rare, though some off-road vehicles still use it.
