This article guides you on adjusting the number of blinks your Audi A6’s comfort turn signals make with a simple tap, using a VCDS (VAG-COM) diagnostic cable. This modification allows you to personalize your driving experience and enhance convenience on the road.
While all MK5 and newer Volkswagen/Audi vehicles feature comfort turn signals, the ability to customize the blink count is often limited to specific models and years. This guide focuses on utilizing VCDS to achieve this customization, specifically for the Audi A6. If your vehicle is a 2009 or earlier model, this modification may not be possible. In those cases, holding the turn signal lever until the desired maneuver is completed remains the standard operation.

Adjusting Audi A6 Comfort Turn Signal Blinks with VCDS
Follow these steps carefully to adjust your turn signal blink count:
-
Connect and Launch: Plug the VCDS cable into your Audi A6’s OBD2 port. Ensure the cable’s green LED illuminates, indicating a successful connection. Launch the VCDS software on your computer.
-
Select Control Module: In the VCDS software, click “Select” and then choose “09 – Central Electrics.” This accesses the Central Electric Control Module (CECM), responsible for various vehicle functions, including turn signals. If connection issues arise, ensure all doors are unlocked and retry.
-
Access Adaptation: Within the “09 – Central Electrics” module, click on “Adaptation.”
-
Modify Channel 31: Navigate to “Channel 31” either by using the up/down arrows or by manually entering “31” and pressing Enter. This channel controls the comfort turn signal blink count. You’ll typically find options to adjust the number of blinks from 1 to 5.
-
Save and Exit: After selecting your desired blink count, click “Save” to confirm the changes. Then, click “Close Controller, Go Back” to exit the module.
Important Note for 2011+ Models: In some 2011 and later models (including potential Golf, Jetta, and other variants), directly modifying Channel 31 might not immediately take effect. A potential workaround involves resetting the lights and vision settings in the Multi-Function Display (MFD):
- Access the MFD menu.
- Navigate to Settings –> Lights and Vision –> Factory Setting.
- Confirm the factory reset prompt.
Additional VCDS Adaptations
While accessing the CECM, consider these other convenience customizations:
-
Comfort Windows/Sunroof: Enable remote control operation of your windows and sunroof (if equipped).
-
Auto Unlock: Automatically unlock doors upon removing the ignition key.
-
Selective Door Locking: Configure the first unlock press on your remote to open only the driver’s door, enhancing security.
This guide provides a foundational understanding of using VCDS to customize your Audi A6’s comfort turn signals. Remember to always exercise caution when modifying vehicle settings and consult official documentation if necessary. Always record your original coding before making any changes. Incorrect modifications could potentially affect vehicle functionality.
