This guide provides instructions on how to enable cycling turn signal lights on a MK7 GTI using VCDS. This modification is intended for vehicles equipped with LED turn signals. Incandescent bulbs are not designed for the increased duty cycle and may overheat.
Important Note: This modification should only be performed on vehicles with LED turn signals. Using this modification with incandescent bulbs may cause overheating and damage to the light fixtures.
Procedure:
-
Access Central Electronics Module: Connect your VCDS cable and open the software. Select “09 – Central Electr control module.”
-
Enter Security Access Code: Navigate to “Security Access – 16” and enter the code “31347.” Return to the “Open Controller” screen.
-
Access Adaptation Channels: Select “Adaptation – 10” from the “Open Controller” screen.
-
Verify Default Settings: Using the pull-down menu, confirm that the adaptation channels listed in the table below match the factory settings provided. This ensures you are starting from the correct configuration.
-
Modify Adaptation Channels: Change the values in the specified adaptation channels to those listed in the “New Setting” column of the table below. There are four adaptation channels to modify for each Leuchte-set, resulting in a total of eight changes. This will enable the cycling turn signal functionality.
-
Optional: Disable Opposite Turn Signal: To deactivate the opposite turn signal while one side is active, modify the adaptation channel in step 3 as needed. This feature can make the cycling turn signals clearer for other drivers. If you prefer the standard behavior, skip this step. This modification improves clarity for other drivers by preventing simultaneous illumination of both turn signals.
Explanation of Modification:
This VCDS modification alters the behavior of the turn signals, causing them to cycle on and off instead of remaining constantly illuminated. By adjusting the duty cycle, the lights illuminate for a shorter duration, creating a distinctive visual effect. The optional modification to disable the opposite turn signal further enhances the clarity of the signal for surrounding traffic.
Conclusion:
Enabling cycling turn signals on your MK7 GTI using VCDS is a straightforward process. By following these instructions and taking necessary precautions, you can achieve a unique visual modification for your vehicle’s lighting system. Remember to verify your vehicle has LED turn signals before proceeding. This modification offers a customized aesthetic enhancement for your MK7 GTI.
