Description
BSI BSI04EV K05-00 JOHNSON CONTROLS for Citroën and Peugeot vehicles. It is from a Citroën C4 2010.
This used BSI (Body System Interface) unit BSI04EV K05-00 by Johnson Controls is a direct replacement option for Citroën and Peugeot comfort electronics. Designed for workshops and experienced DIY mechanics, the module is suitable when the original BSI shows symptoms such as random central locking faults, interior light malfunctions, intermittent indicators or communication errors on the vehicle network. The listing includes common product codes used in searches to help you find the exact match quickly.

Fitment And Compatible Models
Unit originates from Citroën C4 (2010). It is commonly fitted to related PSA group vehicles and may be compatible with certain Citroën and Peugeot models (for example Peugeot 308) that use the BSI04EV K05-00 hardware. Always check product codes against the vehicle’s existing unit when searching.
Function
The BSI is the vehicle comfort and body control module. Typical responsibilities include central locking, interior and exterior lighting logic, wiper and indicator control, power windows, alarm and immobilizer interface, courtesy functions and acting as a gateway on the vehicle CAN networks. Faulty BSI behavior can manifest as electrical gremlins across these systems and network communication errors.
Replacement Procedure
- Prepare: Park on level ground, engage handbrake and remove ignition key.
- Safety first: Disconnect the vehicle battery before any work on the BSI or wiring.
- Access: Remove trim or glovebox panels as required to reach the BSI unit (locations vary by model).
- Disconnect: Unplug all multi-pin connectors carefully, release retaining clips and remove mounting screws.
- Swap or Transfer: If applicable, transfer brackets or sensors from the old unit to the replacement.
- Reinstall: Fit the replacement unit, reconnect connectors and secure mounting hardware.
- Coding/Programming: See Installation and Coding – Important section below for required procedures.
- Final Check: Reconnect battery, perform diagnostic scan for errors and verify operation of comfort functions.
Installation Recommendations
- Always disconnect the negative battery terminal before removal to avoid damage to the unit and vehicle electronics.
- Inspect connectors for corrosion, bent pins or water ingress; clean and repair as necessary before final assembly.
- Secure connectors with dielectric grease where appropriate to reduce future corrosion risk in damp environments.
- Ensure the unit is mounted on its original bracket with correct vibration isolation to prevent solder joint fatigue.
- Use factory-level diagnostics (DiagBox/Lexia/PP2000) or equivalent for configuration and adaptation after installation.
Why The Part Most Commonly Fails
- Water Ingress And Corrosion: Moisture entering the area or connectors causes corrosion and short circuits.
- Thermal And Vibration Stress: Repeated heating/cooling cycles and vibration lead to cracked solder joints or component failure.
- Voltage Spikes And Poor Battery Connections: Electrical surges or intermittent battery supply can damage internal electronics.
- Connector Wear Or Pin Damage: Loose or damaged pins create intermittent faults and communication errors.
Installation And Coding – Important
– The unit is used and is paired with the original vehicle (VIN/PIN/keys).
– Options to commission:
- Cloning data from the old unit (EEPROM/Flash) – after cloning the unit is plug and play.
- Virginization and subsequent initialization/telecoding via DiagBox (or online) + key adaptation.
– Recommended to be performed by a technician with PSA service equipment (DiagBox/Lexia/PP2000).
– Always disconnect the battery before dismantling/installation and follow the manufacturer procedure to avoid damaging the unit.
Notes For Mechanics And DIYers
This BSI unit is intended for experienced technicians and competent DIY mechanics comfortable with vehicle electronics and coding procedures. If you plan to reuse system data, cloning the EEPROM/Flash yields the fastest return to full functionality. If not cloned, the unit must be virginized and programmed to the vehicle with appropriate diagnostic tools to restore immobilizer and comfort functions.
