BMW Retrofit Guide 2026: Every Module and Coding You Can Add After Purchase

Quick Answer

BMW owners can add a wide range of factory features after purchase in 2026. Common retrofits include Smart Comfort Module (window and mirror automation), Anti-Dazzle adaptive headlights, 360 Surround View Camera, Apple CarPlay fullscreen activation, Auto Start-Stop disable modules, and performance ECU/TCU flashes. Plug-and-play modules install in minutes via OBD port; software-locked features require remote coding via ENET cable. Compatibility depends on chassis generation (F vs G series) and I-level firmware version.

What Can You Retrofit on a BMW?

BMW designs their cars with more hardware than software enables. Many features that are exclusive to higher trim levels or optional packages can be activated through coding or added with plug-and-play modules — no dealer visit required.

M-TRI UPGRADE offers BMW retrofit services worldwide: plug-and-play modules that install in minutes and remote coding services completed via TeamViewer. From $79 for individual coding to $459 for complete performance bundles. WhatsApp +6421920905.
