Why can't the Volkswagen SET light be turned off?
1 Answers
It may be because the issue hasn't been fully resolved. The SET light is the tire pressure monitoring light, and its illumination may indicate abnormal tire pressure. When the SET button light is on, you should check if the tire pressure is normal. In most cases, when the SET light comes on, the tire pressure monitoring warning light on the dashboard will also illuminate. After the driver confirms that the tire pressure is insufficient and reinflates the tires, pressing and holding the SET button can turn off the tire pressure monitoring warning light on the dashboard. The reason for the SET light illuminating is abnormal tire pressure. Here are some introductions about abnormal tire pressure: 1. Low tire pressure: If the tire pressure is too low, the tire body deformation increases, cracks are prone to appear on the tire side, and flexing movements occur, leading to excessive heat generation, promoting rubber aging, fatigue of the cord layer, and cord breakage. It also increases the tire's contact area, accelerating shoulder wear. 2. High tire pressure: If the tire pressure is too high, the tire cords will be excessively stretched and deformed, reducing the tire body's elasticity. This increases the load on the car while driving, and impacts may cause internal cracks and explosions. Additionally, high tire pressure accelerates tread wear and reduces puncture resistance.
