Why does the long-press window roll-up function of the Golf key fail?

It may be due to insufficient battery power in the remote key or the window being stuck. Here is some related information about one-touch window roll-up: 1. Introduction: One-touch window roll-up refers to the vehicle's computer receiving a signal from the window roll-up button. Typically, when the window lift switch is lifted and released in less than the set time, the computer sends a continuous roll-up command to the window motor until the window is fully closed. 2. Anti-pinch function: One-touch window roll-up must be used in conjunction with the window anti-pinch function; otherwise, it can easily cause injury due to the strong force of the motor. If there is an anti-pinch function, an additional motor current monitoring and control circuit is included. If the motor current increases beyond a certain range, it indicates that an object is interfering with the window's upward movement, causing motor overload, and the motor will stop.
I recently encountered a similar issue. When driving my Golf home, I noticed that holding down the key to close the windows didn't work. At first, I panicked, thinking there was a major problem with the car. Then I recalled that I last replaced the battery a year ago, so I went to the supermarket to buy a new button battery and tried replacing it. Sure enough, everything returned to normal. Actually, when the key's battery is low, the signal weakens, causing many functions to become sluggish or unresponsive, like the door lock sound not being as crisp. I usually keep the key in my pants pocket, which makes it prone to moisture or pressure. I recommend checking the battery life every six months and testing other remote functions while you're at it. Avoid using the key in rainy weather or areas with strong signal interference. Replacing the battery doesn't cost much, so there's no need to rush to a repair shop for unnecessary hassle.
