Built-in ActivationAudi e-tron GT — US/NAR Matrix & Laser Headlight Activation
Grand-tourer performance, US-restricted headlights — this activation lets your e-tron GT's Matrix & Laser hardware behave the way Audi designed it. From €200 / ~$240 USD.
What You Get
Audi e-tron GT and RS e-tron GT vehicles delivered to the United States and Canada come from the factory with Matrix LED — and on Laser-equipped trims, the Laser hardware — fitted into the sculpted headlight housings. Yet the adaptive high beam functionality is software-restricted before delivery, leaving the GT lighting the road like a regular LED grand tourer despite the premium hardware. This OEM activation re-enables Matrix segment control on the headlight controller and restores the adaptive lighting behaviour the e-tron GT was originally engineered to deliver.
The method and price depend on your PR-code and model year:
- PR-code 8G4 (Matrix LED), 2020–2023: activation runs directly through the RetroLab Pro app. €200 / ~$240 USD.
- PR-code 8G4 (Matrix LED), 2024+: via a guided remote session on a Windows PC + ENet cable. €300 / ~$360 USD (+€100 SFD2 surcharge).
- Without PR-code 8G4, 2020–2023: via a guided remote session on a Windows PC + ENet cable. €300 / ~$360 USD.
- Without PR-code 8G4, 2024+: not supported.
How It Changes Behavior
From factoryon a stock NAR e-tron GT, the Matrix LEDs and Laser unit are physically present but constrained to a fixed full-beam mode. No segment masking, no adaptive cornering, no Laser activation at speed.
After activationthe headlight controller takes back individual control of each Matrix LED segment and engages the Laser at motorway speeds, masking other road users in real time and extending the high-beam range the way the e-tron GT's premium lighting hardware was designed to operate.
- PR-code 8G4, 2020–2023: app activation — €200 / ~$240 USD
- PR-code 8G4, 2024+: remote session — €300 / ~$360 USD
- Without 8G4, 2020–2023: remote session — €300 / ~$360 USD
- Without 8G4, 2024+: not supported
- Laser engagement at motorway speeds (Laser-equipped trims)
- 100% OEM integration — writes new module data, not a coding flag
- Guided, VIN-specific OEM activation workflow
Optional Add-Ons During Activation
The following additional lighting options can be enabled in the same session if desired.
- European single-sided parking light activation (Standlicht)
- Deactivation of orange side markers for a cleaner front-end appearance
- Allow fog / all-weather lighting together with high beam
Why Matrix Headlights Are Restricted on US Vehicles
Audi vehicles delivered to the United States and Canada include factory Matrix LED hardware, but the advanced adaptive lighting functionality is limited at the software level due to regional lighting regulations. Until recently, NHTSA rules did not allow segmented adaptive high beam, so Audi shipped the cars with the feature disabled even though the hardware was present. This activation unlocks the Matrix headlights and allows the adaptive lighting system to operate closer to its intended design — at the discretion of the vehicle owner.
Requirements
- Audi e-tron GT or RS e-tron GT NAR-spec (2020–2023 or 2024+)
- Factory Matrix LED headlights (PR-code 8G4) recommended; some non-8G4 hardware supported via remote session
- Windows PC + ENet cable (required for remote-session vehicles; app-based for PR-code 8G4, 2020–2023 only)
Compatibility Notes
- Not supported: e-tron GE (SUV / Sportback — different platform)
- Not supported: e-tron GT NAR-spec without factory Matrix LED hardware and without 8G4, 2024+
- Not supported: non-North American vehicles (EU / RoW units already ship with Matrix enabled)
Compatible Variants
e-tron GT, RS e-tron GT — FW (2020–2024+) NAR-spec Sportback with Matrix LED (and optional Laser) hardware
