Description
BSI E01-00 HG SIEMENS CITROEN PEUGEOT 9649627780
BSI E01-00 Siemens – original PSA comfort control unit for Citroën/Peugeot. This is a used OEM part that controls the comfort and body functions of the vehicle (central locking, lighting, wipers, turn signals, immobilizer, communication on the VAN bus). Suitable as a replacement for a faulty unit – when the codes match, full compatibility can be achieved after correct coding.
Main OE/REF numbers to look up
– PSA: 9649627780, 1650882380
– Siemens: S118085320A
– Alternative PSA codes/marks: 6580.H2, 6580.FP, 6580.GT (NFP – no longer produced)
– Marking on the label: BSI E01-00 (Siemens/VDO)
Vehicle compatibility
– Citroën Berlingo M49/M59 (approx. 1999–2008, multiplex VAN)
– Citroën Xsara Picasso (approx. 1999–2010)
– Peugeot 206 (approx. 1998–2009)
– Peugeot Partner M49/M59 (approx. 1999–2008)
Note: Real compatibility is mainly governed by the matching of the codes on the label (9649627780 / S118085320A / SW index E01-00) and the car’s equipment. Please compare the numbers and connector design with your original BSI before ordering.
What does the BSI manage?
– Central locking, comfort function, alarm/horn
– Turn signals, lighting, wipers/washers, switching of some relays
– Immobilizer interface, communication with engine ECU and instrument panel
– Diagnostics and telecoding via Lexia/PP2000/DiagBox (VAN network)
When does this part fix the problem
– Self-switching of wipers/lights, turn signal malfunctions
– Central unit falling out, remote not working, problems with immo (unable to start)
– Random electrical faults after loading or after leakage into the interior fuse box
Important for assembly and coding
– Always disconnect the battery before disassembly/assembly (at least 10-15 minutes before work).
– After installation, the BSI must be telecoded to the specific equipment of the car and paired with the immobilizer (PIN code, Lexia/DiagBox).
– The remotes/chips in the keys usually need to be re-adapted.
– Mounting alternatives:
– use “set” (BSI + engine ECU + key chips) – without the need for immo pairing,
– or “virginization/reset” BSI and subsequent encoding into the car.
– Recommended to entrust the coding to an experienced auto mechanic/auto electrician.
Technical information
– Manufacturer: Siemens (VDO)
– Model/Index: BSI E01-00 (VAN multiplex)

Tips for the right choice
– Follow the matching codes: 9649627780 / S118085320A / E01-00.
– Verify network type (VAN vs. CAN) and vehicle equipment (fog lights, AC, sunroof, etc.) to match telecoding.
– If you are not sure, send the VIN and a photo of the original BSI label – we will check compatibility.
