Description
BSM R02 DELPHI for Citroën and Peugeot vehicles. The side guide of the housing is cracked, but this does not affect operation. The unit is fully functional.
Product Overview
The BSM R02 (Body Service Module) by Delphi is a vehicle electrical distribution and relay/fuse module used on numerous Citroën and Peugeot models. It centralizes fuses, relays and power distribution for engine-bay systems and body functions, helping manage lighting circuits, starter/immobilizer circuits, and auxiliary components. This used unit is offered in functional condition despite a minor crack in the side housing guide that is purely cosmetic and does not impair electrical performance.
Compatibility
- Citroën C4 Picasso
- Peugeot 3008 I
- Peugeot 5008 I
- Also compatible with other PSA vehicles using the BSM R02 variant (check vehicle-specific parts lists by code).
Technical Information

- Additional Numbers: 6500FQ, 6500HK
Installation Recommendations
- Always disconnect the vehicle battery before starting work to avoid short circuits or damage to the unit.
- Locate the BSM according to the vehicle service manual (commonly in the engine bay fusebox area or on the inner wing). Remove any trim or covers to access the module.
- Carefully unplug all electrical connectors using proper terminal release tools; avoid pulling on wiring harnesses.
- Unscrew or unclip the module from its mounting. Compare pin counts and connector shapes before fitting the replacement to ensure correct match.
- When installing, ensure connectors fully engage and that all sealing gaskets are intact to prevent moisture ingress. Secure the module and reconnect the battery last.
- After fitment, verify related circuits and fuses. If any functions are missing, consult the vehicle’s repair manual for adaptation or initialization procedures.
- Use personal protective equipment and follow manufacturer torque and safety specifications.
Why This Part Fails Most Often
- Water Ingress And Corrosion: Exposure to moisture and road salts can corrode terminals and printed circuit traces.
- Thermal Stress: Repeated heat cycles in the engine bay can cause solder joints or components to fail.
- Electrical Surges: Faulty alternators, jump-starts, or short circuits may damage internal electronics.
- Mechanical Damage: Impacts or cracked housing (as noted on this unit) can expose the module to contaminants—though minor housing cracks are often cosmetic.
- Age And Wear: Over many years the internal relays, capacitors or connectors can degrade and cause intermittent faults.
Notes For Mechanics And DIY Enthusiasts
This BSM R02 unit offers a cost-effective replacement option for workshops and experienced DIYers. Ensure code numbers match the original part and follow vehicle manufacturer instructions during removal and fitment. For complex electrical symptoms, use diagnostic equipment to trace faults and confirm the BSM is the source before replacement.
