Understanding the “Fog Always On” Mod

The “fog always on” mod leverages the power of VCDS (VAG-COM Diagnostic System), a software tool that allows you to access and modify the control modules within your Volkswagen. By changing specific coding within the front lighting controller, you can instruct the fog lights to activate whenever your DRLs are on.

Why Choose “Fog Always On”?

Many GTI owners opt for this mod for aesthetic reasons. It provides a more balanced and European-inspired look to the front end, especially during daylight hours. The additional light output can also enhance visibility in certain conditions. However, it’s crucial to ensure the increased light output doesn’t cause glare or discomfort to other drivers.
