Description
This Valeo BSI CN2 module is an original body control unit for Citroën and Peugeot vehicles, identified by OEM number 9645872980 and alternate hardware reference 73004511. It is a factory electronic module used within the vehicle’s central electrical and comfort system, and it is suited only where these exact numbers match your existing unit.
The BSI acts as a central communication and control hub for multiple body functions. It manages signals and power distribution for systems such as interior electrics, lighting logic, central locking, wipers, instrument communication, and other comfort-related vehicle electronics, helping the different control units work together correctly.
Common signs of a faulty unit include intermittent electrical faults, central locking problems, non-responsive interior functions, lighting irregularities, communication errors, or starting and immobilizer-related issues linked to body electronics. In some vehicles, a failing BSI can also cause erratic dashboard behavior or unexpected loss of convenience functions.
This is a used original part removed from a vehicle and tested before sale. Always match the exact OEM number before ordering. Professional installation is recommended, and coding, programming, or adaptation may be required for correct integration with the vehicle.
Returns accepted only for genuine faults — faulty on arrival, not as described, or wrong part supplied — requested within 14 days, with all 3 anti-tamper stickers intact. No returns for change of mind, incorrect installation, coding/programming, or buyer compatibility errors; checking compatibility (OEM number, firmware, vehicle) is the buyer’s responsibility.
