The listing includes the most commonly searched product numbers (9663510580, 6580EA) to help technicians find the correct part quickly. Ideal for garages and experienced home mechanics familiar with PSA electronics and coding procedures.

Compatibility And Application

Intended For: Peugeot 407 (example vehicle: 2007). The module is compatible with Citroën/Peugeot models fitted with the BSI 2004 H05-01 hardware and corresponding product codes. Always confirm physical part numbers on the original unit before installation.

How The Unit Is Replaced

Replacement Steps (overview for experienced technicians):

• Disconnect the negative battery terminal and wait several minutes to ensure capacitors discharge.
• Remove lower dashboard trim panels to access the BSI (location varies by model; commonly on the passenger or driver side behind glovebox or under steering column).
• Unscrew mounting fasteners and carefully release the electrical connectors using proper terminal release tools to avoid damaging locking tabs.
• Swap the unit, secure mounting, reconnect all connectors and reassemble trim panels.
• Perform required coding/initialization (see Installation And Coding – Important section below).

Installation And Coding – Important

– The unit is used and is “paired” with the original vehicle (VIN/PIN/keys).
– Options for commissioning:
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).
– Before removal/installation always disconnect the battery and follow the manufacturer’s procedure to avoid damaging the unit.

Common Failure Modes

BSI units commonly fail due to water ingress and consequent corrosion of solder joints or connector pins, electrical surges from a failing alternator or jump-starting incidents, and thermal stress over many years of service. Symptoms include intermittent lighting faults, central locking failures, unexpected immobiliser warnings, blown fuses, or complete loss of certain convenience functions.

Expected Service Life

Service life depends on environmental conditions and vehicle maintenance. In typical use, BSIs on older PSA vehicles may begin to present issues after 10–15 years, particularly if exposed to moisture or repeated electrical disturbances.

Recommendations For Installation

• Ensure the replacement unit matches the part numbers listed on the original unit.
• Always perform cloning or proper initialization/coding with DiagBox or equivalent PSA diagnostic tools to restore full functionality.
• Check and clean connector pins and harness grommets to prevent future corrosion.
• Verify vehicle battery and charging system health before and after installation to avoid damage from voltage spikes.
• If unsure about coding or immobiliser procedures, have the final commissioning done by a workshop with PSA diagnostic equipment.
