Why does Audi always display fog light fault codes?

[MacLaura]

Audi always displaying fog light fault codes requires removing the fog light grille, taking down the fog light, and checking whether the plug and bulb are damaged. Introduction to fog lights: Fog lights (foglamp), also commonly referred to as spotlights. As the name suggests, their primary purpose is to ensure the driver's visibility in adverse weather conditions and to make sure others can see them. However, many manufacturers now install fog lights merely to enhance the aesthetic appeal of the front bumper, often using low-quality fog lights. Similar to headlights, besides replacing them with brighter fog lights, opting for a pair of HID xenon fog lights is also an excellent choice. Attention to fog light installation position: It is important to note that fog lights should only be installed below the bumper, at the lowest point of the vehicle body closest to the ground, to ensure their effectiveness. If installed too high, the light cannot penetrate rain and fog to illuminate the road conditions (fog is generally thinner below 1 meter), which can easily lead to hazards.
