The Audi A3, known for its sleek design and sporty performance, offers a wide range of customization options for enthusiasts. One popular modification is coding the tail lights using a VCDS (VAG-COM Diagnostic System). This article serves as a comprehensive guide to 2015 Audi A3 tail light coding mods, covering everything from understanding the basics to executing specific modifications.

Understanding VCDS and Tail Light Coding

VCDS is a powerful diagnostic and coding tool that allows access to the various control modules within your Audi A3. By modifying the coding within these modules, you can alter the behavior and functionality of different components, including the tail lights.

Tail light coding opens up a world of customization possibilities. Want your brake lights to flash multiple times when you hit the brakes for added safety? Or perhaps you’d prefer a North American-style tail light configuration where the outer lights illuminate with the headlights? VCDS coding makes these changes, and more, achievable.

Popular 2015 Audi A3 Tail Light Coding Mods

Let’s explore some of the most sought-after tail light coding modifications for the 2015 Audi A3:

1. Brake Light Flashing

This modification enhances safety by making your brake lights flash multiple times during hard braking, grabbing the attention of drivers behind you. You can configure the number of flashes and the flash duration using VCDS.

2. North American Tail Light Configuration

This mod alters the tail light behavior to mimic the North American standard where the outer tail lights illuminate alongside the headlights. This not only enhances visibility but also gives your A3 a distinctive look.

3. Coming/Leaving Home Lighting Sequence

By modifying the coming/leaving home lighting settings, you can personalize the illumination sequence of your headlights and tail lights when you approach or leave your vehicle, adding a touch of sophistication.

4. Tail Light Brightness Adjustment

This mod allows you to fine-tune the brightness of your tail lights, providing optimal visibility in various driving conditions. You can adjust the brightness levels for both daytime running lights and brake lights.

Before you begin, it’s crucial to proceed with caution. Incorrect coding can potentially lead to errors or malfunctions. Always back up your existing coding before making any changes.

Connect your VCDS cable to your laptop and the OBD-II port located under the dashboard on the driver’s side of your A3.

Step 2: Access the Tail Light Module

Turn on the ignition and launch the VCDS software. Select “Select Control Module” and choose “[09 – Central Electrics].”
