What You Get

Audi e-tron GE, e-tron S, e-tron Sportback and Q8 e-tron vehicles delivered to the United States come with one of three headlight configurations — Matrix LED (PR-8G4), Digital Matrix (PR-8G5), or Prepared for Matrix (PR-8G9). In all three cases, the adaptive high beam functionality is software-restricted at delivery. This activation re-enables Matrix segment control at the headlight controller level and restores the adaptive lighting behaviour the hardware was engineered to deliver. The activation method depends on your headlight type and model year: PR-8G4 on 2018–2023 runs through the RetroLab Pro app; all other supported combinations are performed via a guided remote session on a Windows PC.

How It Changes Behavior

From factoryon a stock US-spec e-tron or Q8 e-tron, the Matrix hardware is physically present but runs in a fixed full-beam mode — no per-segment masking, no adaptive cornering, no dynamic high-beam behaviour.

After activationthe headlight controller takes back individual control of each Matrix LED segment, masking other road users in real time and extending the adaptive high beam at speed — exactly the way the e-tron's premium lighting hardware was designed to behave.

Always Included

Full Matrix Activation

All individual LED segments activated for real-time adaptive masking of oncoming and preceding traffic.

Highway Light

Extended beam range at motorway speeds for improved long-distance visibility.

Crossing Light with Route Data

Navigation data pre-widens the beam before upcoming intersections.

Fog / All-Weather Light with High Beam

Allows the fog light and Matrix high beam to operate simultaneously in poor visibility conditions.

Optional — No Extra Cost

Amber Light Off

Removes the amber daytime-running accent on some market variants, restoring a clean all-white LED front.

Single-Sided Parking Light

Illuminates only the road-facing side when parked at a kerb, per European road safety norms.

Maneuver Light

Activates door-handle area lights to illuminate the ground beside the vehicle when reversing or maneuvering.

Why Matrix Headlights Are Restricted on US and Canadian e-tron Vehicles

Audi e-tron and Q8 e-tron vehicles delivered to the United States include factory Matrix LED hardware, but the adaptive functionality is limited at the software level due to US 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 system to operate the way Audi designed it — at the discretion of the vehicle owner.

Why the App, Not a Remote Session?

Most providers offering this activation perform it via a remote session — a technician connects to your PC over the internet and runs the process manually. RetroLab Pro does it differently. For 2018–2023 model years the activation runs entirely through the RetroLab Pro app, on your own machine, with no one connecting to your computer.

No one accesses your PC — the activation runs locally. You stay in full control throughout the process.
No scheduling — activate whenever it suits you. No waiting, no appointment, no time zone coordination.
Built-in safety checks — before writing anything, the app verifies your VIN, confirms the correct control unit, and validates the activation data. Incorrect data cannot be sent to the wrong module.
Lower price — Matrix activation via the RetroLab Pro app costs €200. Optional add-ons such as RS Animation or Blue Laser are +€50 each.
Re-activate at any time — if a dealer visit or software update resets the activation, just run it again. Remote session reactivations are always free. The activation is released as a lifetime service for your VIN at no additional charge.

Frequently Asked Questions

How do I know which headlight type my e-tron has?

Check your window sticker or the PR-codes in your vehicle order confirmation. PR-8G4 = Matrix LED (most common), PR-8G5 = Digital Matrix (top-spec option), PR-8G9 = Prepared for Matrix (wiring fitted but no full Matrix module). If you are unsure, send us your VIN and we will confirm before any payment.

I have PR-8G4 Matrix LED — can I use the app?

Yes, if your vehicle is from model year 2018 through 2023. PR-8G4 on those years activates entirely through the RetroLab Pro app on iPhone or Windows PC with an ENet cable (€200). For model years 2024 and 2025, a guided remote session on a Windows PC is required (€300).

I have PR-8G5 Digital Matrix — is that different?

Yes, Digital Matrix uses a pixel-level beam control module that requires a different activation toolchain. For e-tron GE 2018–2023 and Q8 e-tron 2022–2023, PR-8G5 activates fully through the RetroLab Pro app (€200) — Carpet Light (+€50) is also available on these app years. For model years 2024 and 2025, a guided remote session on a Windows PC is required (€300).

Will the activation survive a software update or dealer visit?

Yes. The licence is permanent and VIN-locked — one-time payment, no expiry. Certain dealer software updates (such as an SVM run) or a full module reset can clear it, though a routine service visit won't. Rerun the RetroLab Pro app at no extra charge. Remote session reactivations are always free — lifetime service for your VIN.

Is activating Matrix headlights legal in the United States?

Audi restricted Matrix at the software level to comply with older NHTSA regulations. The hardware is DOT-compliant and factory-installed. The decision to use adaptive high-beam on public roads is at the discretion of the vehicle owner.

Does this work on a Canadian-spec Audi?

Yes. Canadian-spec Audi vehicles are delivered with the same factory Matrix LED hardware as US-spec models — the adaptive beam function is software-restricted at the factory for the same North American regulatory reasons. RetroLab Pro supports NAR-spec (North American Region) vehicles, which covers both US and Canadian market delivery. The activation process, pricing, and hardware requirements are identical.
