- It Is Recommended To Be Performed By A Specialist With PSA Service Equipment (DiagBox/Lexia/PP2000).
- Always Disconnect The Battery Before Removal/Installation And Follow The Manufacturer’S Procedure To Avoid Damaging The Unit.
Installation Recommendations
Before starting work, disconnect the negative battery terminal and wait a few minutes. The BSI on Peugeot 206 is usually located behind the glovebox or under the passenger-side dashboard. To replace it: remove the glovebox or lower the trim panels, unscrew the retaining bolts, carefully release the connector latches and unplug the harnesses. Label connectors if needed to ensure correct reconnection. Avoid pulling on wiring and protect the unit from static discharge. After mechanical replacement, perform data cloning or proper initialization/coding as described above so that immobilizer, key functions and comfort features operate correctly.
Why The Part Most Often Fails
BSI units typically fail due to environmental and electrical causes rather than scheduled wear. The most common reasons are water ingress or moisture causing corrosion, poor or loose connector contacts, voltage spikes or jump-start incidents, and cracked solder joints from vibration or thermal cycling. Symptoms of a failing BSI include intermittent or permanent loss of central locking, dashboard warning lights, non-functional wipers, lighting faults, problems with ignition or immobilizer messages, and malfunctioning power windows.
Notes For Buyers
Search by the listed product codes (9649627880, 9650584680, S118085220) to find matching units quickly. There is no fixed replacement interval for a BSI—reliability depends on vehicle age, exposure to moisture and previous electrical events. Professional cloning or coding is often required to restore full functionality after fitting.
