Owning a 2012 Jetta Sportwagen comes with the opportunity to personalize its features, and one popular modification is activating the mirror blinkers. While not equipped from the factory, these turn signals can be enabled using a VCDS (VAG-COM Diagnostic System). This guide will walk you through the process, explaining what VCDS is, how to use it, and the steps to activate your Jetta’s mirror blinkers.
What is VCDS and Why Do I Need It?
VCDS is a powerful diagnostic and customization software for Volkswagen Audi Group (VAG) vehicles. It allows you to access and modify the various control modules in your car, enabling features that were deactivated from the factory. Think of it as a key that unlocks hidden potential within your Jetta.
“Using a VCDS gives you a deeper level of control over your vehicle,” says automotive electronics expert, Michael Klein, author of “Modern Automotive Electronics and Control Systems.” “It’s a valuable tool for enthusiasts and professionals alike.”
