BMW i4 coding: comfort & display (not powertrain hacks)
How i4 owners use CodexDrive responsibly for user-facing options on electric G-platform architecture.
Scope matters on i4
CodexDrive focuses on comfort, lighting, cluster, and iDrive-related parameters owners expect from BMW coding — not experimental HV battery or drivetrain tampering.
Your scan defines the boundary. Empty list means honest empty.
Connection and security
i4 uses modern Ethernet/DoIP paths. Setup Doctor validates firewall and adapter choice before you spend time on failed connects.
Secure modules may require NCD signing — the app surfaces that path early.
AI for EV owners
Ask for display or lighting behavior in plain English. The copilot maps to EV-appropriate modules only — no promises outside your ECU report.
