A common yet potentially problematic feature in many Volkswagen vehicles, including the Atlas, is the comfort function that allows automatic window closing and opening using the key fob. While convenient, this feature can lead to unintended consequences, such as accidentally leaving windows down overnight. This article explores how to disable the automatic window opening and closing comfort function using VCDS (Vag-Com Diagnostic System) for a Volkswagen Atlas.
Understanding the Problem: Accidental Window Operation
The comfort function on the VW Atlas allows users to open or close all windows by pressing and holding the unlock or lock buttons on the key fob, respectively. However, inadvertent pressure on the key fob buttons, for instance, while in a pocket, can trigger this function unintentionally. This can be particularly troublesome during inclement weather, potentially exposing the vehicle’s interior to the elements or increasing the risk of theft. The owner’s manual often lacks clear documentation on this feature and how to modify it.
Disabling Automatic Window Opening with VCDS
VCDS allows access to the vehicle’s control modules and customization of various settings, including comfort functions. While the specific coding may vary slightly depending on the vehicle’s model year and installed modules, the general process involves accessing the Central Electronics module (address 09 in VCDS) and adjusting the relevant coding bytes.
To disable the automatic window opening feature, follow these steps:
-
Connect VCDS: Connect the VCDS interface to the vehicle’s OBD-II port and launch the VCDS software on your computer.
-
Select Control Module: Navigate to “Select Control Module” and choose “09 – Central Electrics.”
-
Access Coding: Within the Central Electrics module, select “Coding – 07.”
-
Modify Coding Bytes: Locate the specific byte responsible for the comfort window function. This byte’s location can vary, so consulting the VCDS label file for your specific Atlas model is crucial. Within the byte, specific bits control the window opening and closing behavior. Changing the value assigned to these bits will enable or disable the desired function. For instance, setting a specific bit to 0 might disable automatic opening while leaving automatic closing enabled.
-
Execute Coding Change: Once the desired coding changes are made, click “Do It!” to execute the changes and save the new coding to the control module.
-
Test Functionality: After saving the new coding, test the key fob to confirm the automatic window opening has been successfully disabled. The windows should no longer open when pressing and holding the unlock button. The lock button’s function to close the windows might remain unaffected, depending on the coding changes made.
Important Considerations
- Backup Existing Coding: Before making any changes, it’s crucial to save a backup of the original coding. This allows for easy restoration if any issues arise.
- Consult VCDS Label Files: Refer to the Ross-Tech VCDS website or forums for detailed information on the specific coding bytes and bits related to comfort functions for your particular Atlas model year. These label files will provide precise instructions and ensure accurate modifications.
- Professional Assistance: If unsure about modifying the coding yourself, seek assistance from a qualified VAG technician or a reputable VW specialist familiar with VCDS. Incorrect coding changes could potentially affect other vehicle functions.
Conclusion
Disabling the VCDS comfort function for automatic window closing on a Volkswagen Atlas provides a solution for preventing accidental window operation and enhancing vehicle security. By utilizing VCDS and carefully modifying the appropriate coding bytes, owners can tailor this comfort feature to their specific needs and preferences. Remember to always backup the original coding and consult the relevant documentation before implementing any changes. For detailed coding information specific to your vehicle, refer to the Ross-Tech website or their extensive online forums.
