Is it legal to unlock Matrix headlights on my Audi EV in the US and Canada?
Yes. Matrix LED headlights are fully legal in the US and Canada. NHTSA updated FMVSS 108 (effective February 2022) to allow segmented adaptive high beam, and Transport Canada's CMVSS 108 mirrors US standards closely. Canadian-spec Audi e-tron, Q8 e-tron, and e-tron GT vehicles carry the same factory Matrix hardware as US models — the activation process, pricing, and requirements are identical.
Does RetroLab Pro support all three Audi electric models for Matrix activation?
Yes. The Audi e-tron GE (2018–2024), Q8 e-tron (2022–2024), and e-tron GT (2021–2025) are all fully supported. Each model has its own pricing tiers based on headlight hardware (PR-code) and model year.
What is the difference between the Audi e-tron GE and the Q8 e-tron?
The Q8 e-tron is a rebadge of the e-tron GE, renamed by Audi in November 2022. Both share the same platform, the same headlight PR-codes, and the same activation workflow. The main practical difference is the model name on the VIN. Both are covered on their respective model pages.
My Q8 e-tron has "Digital Matrix" headlights — is that different from standard Matrix?
Yes. Digital Matrix (PR-code 8G5) is a premium pixel-level beam control variant. For e-tron GE 2018–2023 and Q8 e-tron 2022–2023, it activates fully via the RetroLab Pro app at €200 — the same price as standard Matrix. Carpet Light (+€50) is also available as an add-on on these app years. For 2024–2025 models, a guided remote session is required (€300). Submit your VIN for a free confirmation of which type you have.
Does the e-tron GT have Laser headlights? What extra features come with them?
Higher trims and all RS e-tron GT models are fitted with factory Laser headlights. Two add-ons are available: Blue Laser Light (+€50), which activates the factory laser projector for an extended high beam reach, and RS Animation (+€50), which enables the RS-style dynamic sweep on lock/unlock. Both are optional and only available on Laser-equipped cars.
Why do electric models cost more for some activations?
The pricing difference is based on headlight hardware variant and model year — not the powertrain. Matrix LED (PR-8G4) and Digital Matrix (PR-8G5) on 2018–2023 e-tron GE, 2022–2023 Q8 e-tron, and 2021–2023 e-tron GT all activate via the app at €200. The €300 tier applies to 2024–2025 vehicles (which require SFD handling) and to PR-8G9 (Prepared for Matrix) which can only be done as a remote session regardless of year.
Why do 2024+ models show two prices — App and Remote?
2024–2025 models with Matrix LED (PR-8G4) or Digital Matrix (PR-8G5) have SFD — Audi's security layer on the headlight module. If you can open the SFD unlock window yourself through the MMI, the activation runs through the RetroLab Pro app at €200, exactly like a 2023 car. If you cannot open SFD, we perform the full activation as a guided remote session at €300 (€200 base + €50 remote handling). We confirm which situation applies when we check your VIN — you know before you pay.
What is SFD, and why does it affect 2024+ Audi activations?
SFD stands for Software Feature Disable — Audi's in-car security mechanism that restricts coding channels on certain modules. On 2024–2025 MLBevo-platform vehicles (e-tron GE, Q8 e-tron, e-tron GT), SFD is active on the headlight control unit. The car's owner must open a timed unlock window through the MMI, during which adaptation channels become accessible. If you can open that window yourself, a RetroLab Pro technician can complete the entire activation through the app at the standard price. If you cannot, we join a guided remote session to assist — that adds a flat remote handling fee. Pre-2024 cars are not affected and activate fully via the app.
Will a dealer service visit or software update clear the Matrix activation?
A routine service visit, oil change, or tyre rotation will not affect it. The activation is written directly into the headlight control module and is VIN-locked. However, an Audi SVM (Software Version Management) update — which dealers run when refreshing control unit software — can overwrite the coding. If that happens, simply rerun the RetroLab Pro app at no extra charge. No recurring fees, no re-purchase required.
What hardware do I need to activate Matrix headlights on my Audi electric vehicle?
A standard ENet cable (~$25 on Amazon) plus a Windows PC with a LAN port, or an iPhone 13/14 with a Lightning-to-LAN adapter, or an iPhone 15/16/17 with a USB-C-to-LAN adapter. Plug the cable into the OBD-II port in the driver-side footwell. No high-voltage system access, no dealer visit, no prior experience required.
