Function

The BSI (Body Systems Interface) is the body control module that manages multiple comfort and convenience systems: central locking, interior lighting, exterior lights signalling, wiper/washer logic, some dashboard communications and gateway functions between vehicle networks. It also interfaces with immobilizer and key recognition circuits on many Peugeot 206 models.

Compatibility And Fitment

Intended for Peugeot 206 applications using the E02-00 Siemens BSI. Always confirm the part numbers listed above against the unit fitted to the vehicle before purchase. This BSI is physically located behind the dashboard area (commonly behind the glovebox or under the steering column) depending on model and year.

Replacement Procedure

1. Disconnect the negative battery terminal and wait a few minutes to discharge capacitors.
2. Access the BSI by removing the relevant trim panels (glovebox or lower dash panels) to reach the module.
3. Label and carefully unplug all multi-pin connectors. Inspect connectors for corrosion or damaged pins.
4. Unscrew the BSI from its mounting, swap the unit and refit in reverse order.
5. Coding or data transfer is typically required so the vehicle recognizes the replacement unit (see Installation And Coding – Important 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.
• It Is Recommended That These Operations Be Performed By A Technician With PSA Service Equipment (DiagBox/Lexia/PP2000).
• Always Disconnect The Battery Before Removal/Installation And Follow Manufacturer Procedures To Avoid Damaging The Unit.

Installation Recommendations

• Perform coding/cloning with the appropriate diagnostic tool to restore immobilizer and comfort functions.
• Check and clean all connector pins and earth points before reconnecting to prevent future faults.
• Protect the unit from electrostatic discharge and avoid handling circuit boards directly.
• Inspect for signs of water ingress in the vehicle interior or footwell areas and repair any seals or routing that may allow moisture to reach the BSI.

Why This Part Most Commonly Fails

• Water Ingress And Corrosion: Moisture reaching the unit or connectors causes oxidation and short circuits.
• Electrical Surges And Poor Aftermarket Fittings: Jump starts, incorrect battery connections or badly installed accessories can damage electronic components.
• Thermal And Mechanical Stress: Repeated heating/cooling cycles and vibration can lead to solder joint cracks or component fatigue.
• Connector Damage: Bent or corroded pins and poor mating can produce intermittent faults that escalate to unit failure.

Notes For Professionals And DIYers

This Siemens BSI E02-00 is an essential comfort and body control module for the Peugeot 206 platform. Because correct vehicle commissioning often requires cloning or specialized telecoding, many workshops will perform the final steps with PSA diagnostic equipment. Before fitting, verify part numbers printed on the original unit and inspect the vehicle for the root cause of the failure (moisture, poor earth, electrical modifications) to prevent repeat faults.

Product Overview

This Siemens BSI (Built-in Systems Interface) control unit is a direct-fit electrical module commonly used on Citroën and Peugeot models. Supplied under part references including 9650584580 and S118085320 B, it manages multiple vehicle functions such as central locking, lighting, wipers, body comfort features and communication between subsystems. Ideal for professional garages and experienced DIY mechanics who search by part number (e.g. 9650584580, 6580P1, 6580P2, 6580L3, 6580FP, 6580GV, S118085320), this unit is compatible with a range of PSA vehicles including Citroën Berlingo, Citroën Xsara Picasso, Peugeot 206 and Peugeot Partner. Installing the correct BSI helps restore proper body-electronics behaviour and eliminates intermittent faults caused by a failing module.

Technical Information

• Manufacturer: Siemens
• Model: BSI E01-00 / E02-00 (SIEMENS Comfort Unit)
• Product Codes: 9650584580, S118085320 B
• Other Numbers: 6580P1, 6580P2, 6580L3, 6580FP, 6580GV, E01-00, E02-00

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 Manufacturer Procedures To Avoid Damaging The Unit.

How To Replace (Brief Guide)

Locate The BSI Unit Typically Behind The Glovebox Or On The Passenger Side Of The Dashboard Depending On Model. Steps Generally Include: Disconnect The Battery; Remove The Glovebox/Trim Panels To Access The BSI; Unplug Electrical Connectors And Unscrew The Module From Its Bracket; Transfer Any Brackets Or Mounts To The Replacement Unit; Refit The Unit, Reconnect Connectors And Reinstall Trim. After Physical Installation, Either Clone The Old Unit’s EEPROM/Flash Or Perform Virginization And Telecoding/Initialization With DiagBox Or Equivalent PSA Diagnostic Tool To Restore Full Functionality.

Recommendations For Installation

• Always Disconnect The Battery Before Starting Work To Prevent Short Circuits And Data Loss.
• Handle The Unit Carefully; Avoid Static Discharge And Excessive Force On Connectors.
• Ensure Connectors And Harnesses Are Clean, Dry And Free Of Corrosion Before Reconnection.
• When Possible, Clone EEPROM/Flash From The Original Unit To Preserve Vehicle-Specific Coding And Key Pairing.
• If Virginizing, Use Official PSA Tools (DiagBox/Lexia/PP2000) For Initialization And Key Adaptation.
• Secure The Unit Firmly To Prevent Vibration-Induced Failures.

Why This Part Most Commonly Fails

BSI Units On PSA Vehicles Tend To Fail Due To Moisture Ingress And Corrosion, Electrical Surges Or Poor Battery/Charging System Health, And Thermal Or Vibration Stress Over Time. Symptoms Of A Faulty BSI Include Intermittent Or Complete Loss Of Central Locking, Malfunctioning Interior/Exterior Lighting, Erratic Wiper Or Washer Operation, Difficulties With Immobilizer/Starting, And Communication Errors With Other Control Modules. Addressing Underlying Causes—Such As Water Leaks, Faulty Alternator, Or Corroded Connectors—Is Essential To Prevent Repeat Failures.
