Technical Information

• Manufacturer: Siemens
• Model: BSI E02-00
• Product Codes: 9652474780, S118085220
• Other Numbers: 1650882680, 165082680, 6580N8, 6580FP, 6580GY, NFP
• Vehicle Fitment: Peugeot 206

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.

This used BSI (Body System Interface) Siemens E01-00 is suitable for a range of Citroën and Peugeot models and is often searched by part numbers such as 9657999680, S118085320 or 1650882480. The unit manages multiple comfort and body functions and is a common replacement item for workshops and DIY mechanics maintaining Xsara Picasso, Berlingo, 206 and Partner vehicles. If you are troubleshooting intermittent electrics, central locking faults, or communication errors on the CAN bus, this BSI unit is a direct-replacement option for compatible vehicles and specified part codes listed below.

Technical Information

• Manufacturer: Siemens
• Model: BSI E01-00
• Product Codes: 9657999680, S118085320, E01-00
• Other Numbers: 1650882480, 1650882680, 650883080, 6580T5, 6580EZ, 6580EY, 6580GY

Function And Fitment

The BSI is the central comfort and body control unit that coordinates lighting, wipers, central locking, interior electronics, switch inputs and acts as a gateway on the vehicle CAN network. A malfunctioning BSI can produce a wide range of symptoms: failure of central locking, intermittent lights, non-working wipers, dashboard warning messages, or loss of certain communication lines between modules. This specific Siemens E01-00 variant is referenced for Citroën Xsara Picasso and Berlingo, and for Peugeot 206 and Partner in compatible configurations.

Replacement Procedure

Typical replacement steps for a competent mechanic or experienced DIYer:

• Disconnect the negative battery terminal before any work to avoid electrical damage.
• Access the BSI unit, normally located under the dashboard on the passenger side (behind the glovebox or lower trim) on the listed models.
• Remove surrounding trim and any retaining screws to free the unit.
• Carefully unplug all multi-pin connectors; note their positions and locking tabs.
• Install the replacement BSI, secure mounting screws and refit connectors ensuring full engagement.
• Proceed with the required coding or data transfer steps (see Installation and Coding – Important below) before reconnecting all systems and the battery.

Installation Recommendation

• Perform mounting and electrical work in a dry, well-lit area and use proper anti-static precautions.
• Verify connector pins and wiring harness condition before installation; corroded pins should be cleaned or replaced.
• After installation, check all controlled functions (lights, wipers, locks, dashboard messages) and perform a road test to confirm correct operation.

Installation and Coding – Important

– The Unit Is Used And Is “Paired” With The Original Vehicle (VIN/PIN/Keys).

– Options To Bring The Unit Into Service:

1. Kloning 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 Technician With PSA Service Equipment (DiagBox/Lexia/PP2000).

– Always Disconnect The Battery Before Removal/Installation And Follow Manufacturer Procedures To Avoid Damaging The Unit.

Why This Part Fails Most Often

• Water Ingress And Humidity: Moisture entering the passenger footwell or dashboard area causes corrosion and short-circuits on the PCB or connectors.
• Electrical Surges Or Poor Grounding: Voltage spikes, jump-starting errors or bad grounds can damage internal components.
• Thermal Stress And Solder Joint Fatigue: Repeated heating and cooling cycles may cause cracked solder joints or component failures.
• Connector Corrosion And Wiring Damage: Corroded pins or damaged harnesses lead to intermittent faults and communication errors.

Symptoms To Watch For: Intermittent or permanent failure of central locking, erratic lighting, non-working wipers, dashboard communication errors, or immobilizer-related starting faults when coding/pairing is lost.

Order this Siemens BSI E01-00 if the listed part numbers match your vehicle’s unit and you require a replacement BSI for Citroën Xsara Picasso, Citroën Berlingo, Peugeot 206 or Peugeot Partner. Installation and proper coding/cloning are critical for full restoration of functionality.
