Description
BSM DELPHI R02-00 for CITROEN and PEUGEOT vehicles. It may have a cracked mounting tab on the casing which does not affect function. The unit is fully functional.
This Body System Module (BSM) R02-00 is a direct-fit electrical control and fuse/relay distribution unit used on a range of Stellantis Citroën and Peugeot models. Supplied with OEM cross-references 9664705980 and 9807028580 (also referenced as 6500FQ / 6500HK), the module handles multiple body and comfort functions and is suitable for professional workshops and experienced DIY mechanics seeking a reliable replacement part.
Features And Function
The BSM centralises power distribution and switching for numerous vehicle circuits. Typical responsibilities include powering and switching relays and fuses, controlling lighting circuits, wiper and washer functions, central locking, power windows, horn and auxiliary circuits. It also provides interfaces to other control units in the vehicle to coordinate body functions. A properly functioning BSM is essential for stable electrical behaviour and reliable operation of comfort and safety-related systems.
Compatible Models
Commonly fitted to the following models (verify part codes before installation):
- Peugeot 5008 I
- Citroën C4 Picasso
- Citroën C5 X7
- Peugeot 407
Technical Information
- Manufacturer: Delphi / Siemens
- Model: BSM R02-00
- Product Codes: 9664705980, 9807028580
- Additional Numbers: 6500FQ, 6500HK
Installation Recommendations
- Disconnect the negative battery terminal before starting work and wait at least one minute to reduce risk of damage to electronic modules.
- Locate the BSM according to your vehicle’s layout (position can vary by model and year). Protect surrounding wiring and trim when accessing the unit.
- Label connectors or take photos before unplugging to ensure correct reconnection. Inspect connector pins and clean any corrosion; use dielectric grease if appropriate.
- If the unit has a cracked mounting tab (noted in this item), secure the module so it cannot move; cosmetic damage to a bracket does not affect electrical function but loose mounting must be avoided.
- After installation, reconnect the battery, check all related fuses, start the vehicle and verify operation of lights, wipers, central locking, windows and other affected circuits.
- Clear fault codes and recheck. If persistent faults remain, use an appropriate diagnostic tool to read live data and fault logs.
Why The Part Most Often Fails
- Moisture Ingress And Corrosion: Water penetration or condensation leads to corrosion of connectors and internal PCB traces.
- Electrical Overloads Or Short Circuits: Faults in downstream wiring or accessories can overload relays or internal components.
- Thermal Stress And Ageing: Repeated heating and cooling cycles degrade solder joints and electronic components over time.
- Physical Damage Or Vibration: Impact or constant vibration can break solder joints or damage connectors; mounting failures increase risk.
- Poor Connector Contact: Dirty or loose pins create intermittent faults that may appear as module failure.
How To Replace – General Guidance
- Prepare Basic Tools: socket set, trim tools, small screwdrivers, electrical contact cleaner, multimeter and OBD scanner if available.
- Safety First: Disconnect the battery and follow electrostatic discharge precautions when handling electronic modules.
- Remove Trim And Access Covers: Carefully remove panels securing access to the BSM. Keep fasteners organized.
- Document Connections: Photograph the unit and connectors. Unplug connectors by releasing locking tabs—do not pull on wires.
- Swap The Unit: Remove mounting fasteners, fit the replacement, reconnect all plugs and secure the module firmly.
- Verify Operation: Reconnect battery, verify all functions controlled by the BSM, clear any stored fault codes and perform a short test drive to confirm reliability.
Note: This unit may show a cracked mounting tab on the housing; this cosmetic issue does not affect electrical operation but ensure the module is securely mounted to prevent vibration damage.
