Audi A4 B9 Matrix Headlights Canada — 2020, 2021, 2022 & 2023 Guide

The Audi A4 B9.5 facelift delivered to Canada from the 2020 model year brought factory Matrix LED headlights to the A4 lineup. Canadian and US A4 models are the same NAR build — the hardware restriction and the activation process are identical across both markets.

Which A4 Model Years Are Supported in Canada?

Matrix headlight activation is available on 2020, 2021, 2022, and 2023 Canadian-spec Audi A4 B9 vehicles.

The B9.5 facelift introduced Matrix LED headlights as an available option for the North American market. Canadian and US A4 vehicles are built to the same NAR specification — the Matrix hardware is present in both markets on Prestige or Technology Package trim.

Required: factory Matrix LED headlights (PR-code 8G4). Check your window sticker or myAudi app — if "Matrix LED Headlights" is listed, the hardware is present.

What Gets Unlocked?

Activating Matrix headlights on your Canadian A4 restores the full adaptive high-beam system:

  • Adaptive High Beam Assist — LED segments mask oncoming drivers and cyclists in real time
  • Cornering Light — illuminates turns before the car rotates
  • Highway Mode — extended beam range at higher speeds
  • Intersection Mode — wider spread at low-speed junctions
  • Dynamic Beam Distribution — adapts to speed, steering, and road conditions

The A4 B9.5 has the same Matrix LED architecture as the European version — the activation re-enables what Audi locked for the NAR market.

How It Works & What You Need

The A4 B9 Matrix activation runs through the RetroLab Pro app — no dealer, no VCDS.

What you need:

  • Windows PC + ENet cable (~$25 on Amazon), or
  • iPhone 13/14 + Lightning-to-LAN adapter, or
  • iPhone 15/16/17 + USB-C-to-LAN adapter

Price: €200 / ~$240 USD — one-time, permanent, VIN-locked. Takes 15–20 minutes. No subscription.

Frequently Asked Questions

Does the A4 Matrix activation work the same way in Canada as in the US?
Yes. Canadian and US Audi A4 B9 vehicles are the same NAR build with identical Matrix LED hardware. The activation process, pricing, and requirements are identical regardless of whether your car was delivered in Canada or the US.
Does my 2020 Canadian Audi A4 have Matrix headlights?
If your 2020 A4 B9.5 has Prestige trim or the Technology Package with Matrix LED listed on the window sticker or in myAudi, you have PR-code 8G4 and can activate for €200 / ~$240 USD. Pre-facelift 2019 A4 B9 models do not have Matrix hardware.
Does A4 Matrix activation require VCDS?
No. VCDS cannot perform the full OEM Matrix activation. RetroLab Pro writes the correct module data directly through the standard Audi diagnostic interface — the same way Audi does in production — via the RetroLab Pro app on iPhone or Windows PC with an ENet cable.
