The Audi A4 B8 (8K) and A5 B8 (8T) platforms offer a wealth of customization options accessible through the VCDS (Vag-Com Diagnostic System) software. This guide provides instructions for several popular tweaks using VCDS, focusing on enhancing your Audi driving experience. It’s crucial to use the latest VCDS software version with a genuine Ross-Tech HEX-COM+CAN or HEX-USB+CAN interface for optimal compatibility and to avoid potential issues.

These adjustments can range from simple convenience features to more advanced performance tuning. Before proceeding, remember that modifying your vehicle’s settings can have unintended consequences. Proceed with caution and at your own risk. Detailed diagnostic procedures and further information can be found on the Ross-Tech Wiki:
