Commonly searched by part numbers 9660105780, 6580CX, 6580KC and 1660728380.
Compatibility And Origin
Unit removed from Peugeot 307 1.6 16V, year 2007. Compatibility with other Citroën/Peugeot models is possible but must be confirmed by exact part number, hardware/software index (H03-01), VIN and vehicle equipment. Matching references is critical because pinout, configuration and firmware versions may differ.
Symptoms And Causes
Failing BSI modules on older PSA vehicles typically cause intermittent electrical faults (lights, wipers, indicators, central locking), diagnostic communication errors and, in some cases, inability to start due to immobilizer issues. Common causes include moisture ingress, connector oxidation and voltage spikes from jump-starts or a discharged battery.
Replacement, Coding And Installation
When replacing the BSI you must transfer immobilizer data and configuration (memory cloning) or set the unit to a virgin state and then program it and pair the vehicle keys using PSA diagnostic tools (DiagBox/Lexia/PP2000). Follow correct battery disconnection procedure: switch off ignition, lock the vehicle, wait several minutes for modules to sleep, then disconnect the negative terminal. After installation reconnect the battery, perform coding and verify all functions.
