Description
BSI BSI04EV K05-00 Johnson Controls for Citroën and Peugeot vehicles. It is from a Peugeot 308.
The BSI (Body Systems Interface) BSI04EV K05-00 by Johnson Controls is the central comfort and convenience control unit used in many Citroën and Peugeot models. It controls central locking, interior and exterior lighting, wipers, power windows, alarm/immobilizer logic and other comfort functions. This unit is commonly searched by its part numbers (9664059180, 02 6580SP, 1663371880, 6570A0), so listing product codes helps mechanics and DIYers find the correct replacement quickly. The module is ideal for workshops and experienced home mechanics looking for an original equipment unit removed from a Peugeot 308.
Technical Information
- Manufacturer: Johnson Controls
- Model: BSI04EV K05-00
- Product Codes: 9664059180; 02 6580SP
- Other Numbers: 1663371880; 6570A0
Installation
Basic replacement overview for qualified technicians and competent DIYers:
- Disconnect the negative battery terminal before any work.
- Access the BSI unit (commonly located behind the glovebox or under the steering column depending on model).
- Remove surrounding trims and covers to reach mounting screws and connectors.
- Label and carefully disconnect all electrical connectors, then remove the unit from its bracket.
- Install the replacement unit, secure mounting hardware, reconnect all connectors ensuring proper engagement, reassemble trims and reconnect the battery.
After mechanical installation the unit will generally require cloning or coding to restore immobilizer and key functions. See the Installation and Coding section below.
Installation and Coding – Important
– The Unit Is Used And Is “Paired” With The Original Vehicle (VIN/PIN/Keys).
– Possible Commissioning Options:
1) Cloning Data From The Old Unit (EEPROM/Flash) – After Cloning The Unit Is Plug And Play.
2) Virginization And Subsequent Initialization/Telecoding Via DiagBox (Or Online) + Key Adaptation.
– Recommended To Be Performed By A Specialist With PSA Service Equipment (DiagBox/Lexia/PP2000).
– Always Disconnect The Battery Before Removal/Installation And Follow Manufacturer Procedures To Avoid Damaging The Unit.
Recommended For Installation
BSI units normally require specialized diagnostic equipment and software to clone or code the module correctly. For reliable commissioning we recommend a professional workshop with PSA diagnostic tools. Experienced DIYers with the appropriate tools may perform the swap and cloning themselves, but must follow safe handling and anti-static procedures.
Why It Most Commonly Fails
Common causes of BSI failures include:
- Moisture ingress and connector corrosion leading to short circuits or PCB damage.
- Electrical surges, poor grounding or wiring faults that stress internal electronics.
- Age-related thermal stress and cracked solder joints causing intermittent communication faults.
- Oxidation of connector pins and mechanical wear from repeated disconnects.
Typical symptoms are malfunctioning central locking, unpredictable lighting behavior, non-responsive wipers or windows, false alarm triggers, or loss of communication with diagnostic tools.
Fitment And Notes
Commonly Compatible Models: Peugeot 308, Citroën C4. Always check part numbers listed in Technical Information against the vehicle’s existing unit to confirm match. This listing includes original OEM codes to help identify correct compatibility.
Handling And Safety
Handle the unit carefully to avoid static discharge and mechanical damage. Always disconnect the battery before removal or installation and follow vehicle manufacturer instructions for airbag and electrical safety.
