Description
OEM part number 92309449-01, supplier code 5WK49985MBR. [[BMW]] F10 5 Series CAS4 Car Access System 4 control module with Code Guard (CG) anti-theft encryption and Electronic Steering Lock (ELV) integration. Genuine used, tested to confirm correct operation before despatch. ¶ The CAS4 manages immobiliser operation, encrypted key code authentication, engine start authorisation, remote central locking, and electronic steering lock control. It is a VIN-specific security component fully paired to the vehicle’s key set, engine ECU, and ELV unit using advanced cryptographic protocols. ¶ Symptoms of failure include the engine refusing to start, the steering lock failing to release, the key not being recognised, remote central locking becoming inoperative, or multiple security-related fault codes stored in the vehicle’s diagnostic system. ¶ Professional installation is essential. ISTA programming, ISN synchronisation with the engine ECU, electronic steering lock (ELV) initialisation, and key adaptation are all required — specialist access and tools are necessary.
