Could you build this?

No Communicating with vehicle ECUs over BMW proprietary OBD-II/K+DCAN protocols requires deep automotive engineering knowledge and reverse-engineered automotive diagnostic protocol stacks.

What it would actually take: Requires low-level serial communication with FTDI USB drivers on macOS, implementing ISO 14230 (KWP2000), ISO 15765 (UDS over CAN), and BMW's proprietary EDIABAS/DS2 diagnostic protocols. The core difficulty lies in correct message framing, ECU initialization sequences, handling security seeds/keys, and parsing proprietary BMW SGBD/PRG diagnostic data tables. This necessitates specialized automotive embedded systems and reverse-engineering skills.
