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.
From my driving experience, there are several common reasons why the long-press window-up function fails in a Golf: issues with the key itself, such as a dead battery or a stuck, aged button; problems with the car's system, like poor contact in the window control module or a blown fuse; and signal interference, such as misoperation when parked near high-voltage power lines. A simple solution is to first test with a new battery. If that doesn't work, check if the physical buttons on the key are smooth and free of dust. For the car's part, locate the fuse box—usually under the right cover in the engine compartment—and replace the corresponding fuse. If the issue persists, it might be a software problem requiring a reset. Try turning on the ignition, then press and hold the window-down button followed by several window-up attempts to refresh the system. When dealing with such issues, avoid disassembling the car yourself—safety first, and consult a professional.
Golf key malfunction is really troublesome. I was quite anxious when my car window wouldn't roll up that time, as parking outdoors at night might attract thieves. The first thing I did was check the key's appearance, and since there was no damage, I tried replacing the battery, which worked. Reminding everyone not to overlook small details—if even basic locking doesn't work, quickly check the car battery voltage or wiring contact issues. Long-press function failure could also be due to system overload or accidental triggering, so it's recommended to restart the key or briefly press other buttons to test responsiveness. Daily care for the key includes keeping it away from moisture and impacts.
