This guide provides a comprehensive list of VCDS modifications specifically for Audi A4/S4 B8 models, focusing on how to enable side turn signal lights (also known as amber side markers) using VCDS. We’ll cover various coding adjustments you can make to customize your vehicle’s lighting and other features. Disclaimer: Modifying your vehicle’s settings with VCDS can have unintended consequences. Proceed with caution and at your own risk. vcdstool.com is not responsible for any damage.
Understanding VCDS and its Capabilities
VCDS (VAG-COM Diagnostic System) is a powerful software tool that allows you to access and modify the control modules in your Audi. This enables customization of various features, including lighting, convenience, and even performance parameters. Before making any changes, ensure you have a genuine VCDS interface and a basic understanding of how to use the software.
Enabling Side Turn Signal Lights as Parking Lights
In North American Audi A4/S4 B8 models, the amber side markers typically function only as turn signals. Using VCDS, you can enable them to function as parking lights as well, providing a more distinct visual signature at night. This modification involves changing the coding in the Central Electrics module.
Here’s how to enable your side turn signal lights as parking lights:
- Connect VCDS: Connect your VCDS interface to your vehicle’s OBD-II port and launch the VCDS software.
- Select Module: Select “09 – Cent. Elect.”
- Coding – 07: Go to “Coding – 07”.
- Long Coding Helper: Access the “Long Coding Helper”.
- Byte 10, Bit 0: Locate “Byte 10” and find “Bit 0”.
- Enable: Check the box for “Bit 0” or change its value to “1”. This will enable the front turn signals as parking lights. This modification will result in your front turn signals illuminating with reduced intensity when your parking lights are on.
Additional Lighting Modifications with VCDS
Beyond enabling side turn signal lights as parking lights, VCDS allows for numerous other lighting customizations:
- Disable Amber Corner Lights: Deactivate the amber cornering lights within the headlight housing. (Byte 10, Submodule 0, Bit 3, set to 0 in module 09)
- Daytime Running Lights (DRLs): Configure DRL behavior using various light sources, including high beams, fog lights, LEDs, and tail lights. (Byte 2, Bits 1-7 in module 09)
- Tail Lights with DRLs: Activate the rear tail lights along with the DRLs. (Byte 2, Bit 7 in module 09)
- Euro Parking Lights: Enable European-style parking lights, where only one side illuminates when the turn signal is activated at night. (Byte 9, Bit 0, set to 1 in module 09)
- LED Brightness Adjustment: Fine-tune the brightness of your LED lights. (Channel 3 in module 09 – Security Access required)
Conclusion
Using VCDS to modify your Audi A4/S4 B8’s lighting provides a level of customization not available through standard settings. Enabling side turn signal lights as parking lights enhances visibility and adds a unique touch to your vehicle’s appearance. Remember to proceed cautiously and consult reputable sources before making any changes with VCDS. Always back up your original coding before implementing any modifications.
