From checkout to first coding session
Three steps. Mandatory backup. Options only from your ECUs — plus NCD when BMW requires signatures.
01
Buy & activate
Secure checkout → CDX key → download Windows app.
02
Diagnose & backup
Connect, deep scan, mandatory verified backup.
03
Code with AI
Hidden options, Quick jobs, or NCD path with support.
Safety
Backup is non-negotiable
CodexDrive blocks writes until a verified snapshot exists. Empty option list? Ignition ON, run Setup Doctor, scan again — honest empty beats fake toggles.
