1‑Click Taillight Animation for Audi A4 / A5 B9.5 (2020–2023)

TL;DR: This guide shows you how to activate OEM RS and S taillight animations on Audi A4/A5 B9.5 (2020–2023) using our 1-click Retrofit.nu Taillight Animation Activator, an ENet cable and a laptop — no dealer tools, no remote coding.

Until now, activating RS or S-style taillight animations on the Audi A4/A5 B9.5 required expensive dealership tools like VAS5054 or VAS6154, and remote coding sessions that had to be scheduled across time zones. This made the process slow, complicated, and often frustrating for customers.

That’s why we built the Retrofit.nu Taillight Animation Activator — a standalone Windows tool that lets you enable RS/S animations instantly using only an ENet cable and your laptop. No remote coding. No dealer hardware. Just plug in and press one button.

What You Need

• A Windows laptop with internet connection
• An ENet (OBD ↔ LAN) cable – buy it here
• Optional: USB-to-LAN adapter (if your laptop lacks a LAN port)
• The Retrofit.nu Activator app (free)
• VIN license (€100) — unlimited use for your vehicle

Compatible Vehicles

This tool works with all Audi A4 and A5 facelift models (B9.5, 2020–2023) equipped with:

• Factory LED taillights with dynamic indicators
• PR code: 8VM (rear lights with dynamic turn signals)

Note: Not compatible with 2024+ vehicles equipped with SFD2. Only 2020–2023 cars without SFD2 are supported.

How It Works

1. Connect your laptop to the car using an ENet cable (USB–LAN adapter if needed).
2. Launch the app — it automatically reads your VIN and checks the license status.
3. If your VIN is licensed, activate the taillight animation instantly with one click.

If your VIN is not licensed yet, the app will show you how to purchase a license instantly — no account, no registration.
