The VCDS (VAG-COM Diagnostic System) allows access to the hidden settings within your Audi’s control modules. One of the most interesting modules to explore is Central Convenience (Module 46), specifically Byte 1 of its long coding. This byte controls various comfort and convenience features in your vehicle. While this guide focuses on Byte 1, we’ll also touch on other useful tweaks within Module 46 and other modules accessible via VCDS. This article aims to provide a comprehensive overview of common modifications achievable with VCDS, focusing on 2017/2018 Audi models like the A4, A5, Q5, and Q7.

- Access: Adaptation
- Channel: “Deactivate seat belt warning”
- Change: Default value “No” to “Yes”
Adjust Parking Assist Camera Shut-off Speed: Modify the speed at which the parking camera automatically deactivates. Requires a rearview camera or parking assistance package.
- Coding: Module 09 (Central Electrics)
- Access: Adaptation
- Channel: “Switch off speed for park assist”
- Change: Adjust the value to your desired speed (default is typically 6 mph).
Combine Parking Assist Views: Integrate the 360° camera view with the Optical Parking Sensors (OPS) display.
- Coding: Module 09 (Instruments)
- Access: Adaptation
- Channel:
IDE01170-Visual display for park assist - Change: Modify the stored value from the default OPS display to OPS 360°.
Adjust Ventilated Seat Cooling Fan Speeds: Fine-tune the fan speed for each of the three ventilated seat settings (up to a 10% increase).
- Coding: Access specific adaptation channels for each stage (1, 2, and 3) within Module controlling seat functions (likely Module 52 – Seat Memory Driver Side or a similar module).
- Access: Adaptation
- Channels:
IDE10322-MAS01364(Stage 1),IDE10322-MAS01365(Stage 2),IDE10322-MAS01366(Stage 3) - Change: Adjust the stored value for each stage to increase fan speed (maximum 10%).
Modify Lane Assist Steering Intervention: Adjust the sensitivity of the lane keeping assist system.
- Coding: Module for Front Sensor Driver Assist (likely Module A5)
- Access: Adaptation
- Channel:
IDE05984-Directional stabilization assist driver inact deactiv threshold - Change: Adjust the stored value to “Late” for less frequent intervention.
Conclusion
This guide provides a starting point for exploring the customization options available through VCDS. Remember to always proceed with caution and research thoroughly before making any changes to your vehicle’s coding. While these modifications generally carry low risk, it’s crucial to understand the potential impact of each adjustment. Enjoy the process of personalizing your Audi to better suit your preferences and enhance your driving experience.
