Description
BSM Delphi R02-00 for Citroën and Peugeot vehicles. It may have a cracked mounting tab on the housing which does not affect function. The unit is fully functional.
Overview
This BSM (Body System Module) R02-00 is a direct-fit electrical control unit used on various Citroën and Peugeot models. The module manages numerous body and convenience functions such as central locking, interior lighting, power windows, exterior lights, wipers and some vehicle comfort features. Commonly referenced by part numbers 9666700180 and 9807028580, it is regularly searched for by technicians and DIYers by these codes.
Compatibility
Typical vehicle applications (please verify year/variant against your vehicle): Peugeot 5008 I, Peugeot 407, Citroën C4 Picasso, Citroën C5 X7. Also commonly cross-referenced with codes 6500FQ and 6500HK. Always check the physical connector layout and part numbering when replacing.
Installation Recommendations
Disconnect the vehicle battery before starting work and follow manufacturer procedures to avoid electrical damage. Locate the BSM (position varies by model — commonly in the engine bay or inside a fuse/relay box behind the dash). Remove any retaining clips or screws, carefully unplug wiring connectors using lock release tabs, and transfer any necessary mounting brackets or grommets. Reconnect connectors firmly and restore battery power only after the unit is securely installed. After installation, verify all controlled functions (lights, central locking, windows, wipers, interior lights) to confirm correct operation.

Most Common Failure Reasons
BSM units typically fail due to moisture ingress and corrosion of connectors or internal circuits, thermal stress from engine-bay heat cycles, electrical surges (short circuits or poor battery connections) and internal component aging. Physical damage to mounting tabs or housing does not necessarily affect electrical function — as noted, a cracked housing mount can be cosmetic only. Regular inspection of seals, connector pins and fuse box condition helps prevent failures.
Notes
This unit is offered as a fully functional used BSM. Inspect connector pins and housing condition before installation. Replacement often restores multiple body functions at once and is a common repair for intermittent or complete loss of convenience systems.
