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).
