BMW G20: hidden options and NCD-aware coding
G20 3 Series — mixing direct comfort coding with CodexDrive’s signed NCD path when secure modules require it.
G20 is not one single workflow
Software year and module mix decide whether a change is a straightforward ON/OFF or needs signed NCD. CodexDrive classifies after scan — not from a forum post dated 2019.
Hidden factory options still exist on G20: lighting, access, display — but only if your ECU list shows them post-backup.
AI helps you plan safely
Describe the outcome you want. The copilot ties natural language to readable parameters and flags when a module needs the Advanced signing route instead of direct write.
That saves hours of guessing which G20 posts apply to your exact integration level.
When NCD signing appears
Follow in-app Advanced guidance: export, sign, import, apply. CodexDrive keeps backup and documentation in one workshop instead of scattered tools.
