OEM activation for enabling QQ2 Multicolor ambient lighting on Audi e-tron GE models. This activation is intended for vehicles where the correct OEM ambient lighting hardware for QQ2 has already been installed. It unlocks full multicolor ambient light functionality with factory-level integration and control via the infotainment system. The activation is carried out using RetroLab Pro — no manual coding or remote session required.
This activation is intended for vehicles where original OEM QQ2 ambient lighting hardware has been properly installed. It is not compatible with QQ1 (single color) systems or vehicles lacking factory ambient lighting wiring and modules. Only genuine OEM components are supported.
If you purchase the complete QQ2 Multicolor retrofit kit from our shop, this activation is already included. This standalone activation is intended for customers who source and install the OEM hardware themselves.
After purchase, the activation is assigned to your vehicle’s VIN. Using a Windows PC and an ENet cable, you connect to the vehicle and perform the activation using RetroLab Pro. The required OEM configuration is applied automatically.
Starting from model year 2024, most Audi vehicles are equipped with SFD2 (Schutz der Fahrzeugdiagnose 2) security protection. This system prevents remote coding, dataset uploads and activations outside of authorized workshop environments.
If your vehicle has one of the following PR codes, it is protected by SFD2:
Vehicles with SFD2 cannot be activated remotely.
For these vehicles, we only offer installation and activation at our workshop in Vellinge, Sweden. If you are unsure whether your vehicle has SFD2, please contact us before ordering.
All coding, adaptations and feature activations are performed using RetroLab Pro. No third-party tools, scripts or manual coding are required.
Hardware installation must be carried out according to Audi factory repair manuals and wiring diagrams. We do not provide trim removal or mechanical disassembly guides.
You must be comfortable working on your vehicle or have a professional workshop perform the installation. Remote activation support is available if required (additional cost may apply).
