M-Tri Upgrade is a specialist BMW aftermarket shop based in Auckland, New Zealand. We supply premium plug-and-play modules, remote coding services, and performance tuning for BMW vehicles worldwide.

What We Do

We help BMW owners unlock the full potential of their vehicles — from comfort features and infotainment upgrades to ECU and TCU performance tunes. Every product we sell is selected for quality, compatibility, and ease of installation.

Plug-and-Play Modules

Our modules require no coding, no wiring, and no special tools. Simply plug in and enjoy features like auto window-up, ambient light control, start/stop memory, and more. Most installations take 5–15 minutes.

Remote Coding & Flashing

Our professional remote coding services are performed via TeamViewer. We can activate features like anti-dazzle headlights, full-screen CarPlay, and iDrive upgrades — all from the comfort of your home.
