Description
BSM R09 DELPHI unit for Citroën Peugeot vehicles. This is a used part with a warranty of functionality. Some of the mounting brackets may be damaged – this does not affect functionality.
Product Overview
The BSM R09 (Delphi) is a body and power distribution module commonly found on a range of PSA vehicles. It houses fuses and relays that distribute power to the engine and body systems and can be searched by reference numbers such as 9667199780, 6500HV or 6500HW. Supplied as a functional used unit with warranty, it is an economical replacement for workshops and DIY mechanics who need a direct, quick solution.
Compatibility
Function
The BSM controls power distribution for multiple circuits: fuses and relays for lighting, starter, fuel pump, wipers, central locking and other body functions depending on vehicle equipment. It acts as the main fuse box, combining protective elements and relay switching in one module.
Symptoms And Common Failures
Typical signs of a failing BSM include intermittent loss of power to body circuits (lights, wipers, central locking), blown fuses, electrical shorts, or specific relays not operating. Common causes are water ingress or corrosion at connectors, thermal stress and burnt tracks or relays. Mechanical damage to plastic mounting tabs is cosmetic and does not affect electrical operation.
Replacement Procedure
- Ensure vehicle is parked, ignition off and batteries discharged. Disconnect the negative battery terminal before any work.
- Locate the BSM unit (typically in the engine bay or inner wing). Remove protective covers and fuses as needed.
- Label and carefully disconnect wiring connectors and any relay/fuse holders.
- Unbolt or unclip the module and remove it from the vehicle. Note any broken clips mentioned in the listing.
- Install the replacement unit, reconnect connectors, replace fuses/relays and reattach covers.
- Reconnect battery and verify all related systems function. If faults persist, perform electrical diagnosis with appropriate tools.
Installation Recommendations
- Always Disconnect The Battery Before Removal To Avoid Short Circuits.
- Inspect Connectors For Corrosion Or Water Damage And Clean Or Repair As Needed.
- Secure The Unit Firmly; Replace Any Broken Clips With Suitable Fixings To Prevent Vibration Damage.
- Check Related Fuses And Relays After Installation; Replace Any Damaged Components.
- If Electrical Faults Remain, Use A Diagnostic Tool To Read Fault Codes And Trace Wiring.
Why This Part Most Often Fails
Failures are most often caused by moisture ingress and corrosion at the connector pins or on the PCB, overheating from high current draws or repeated thermal cycling, and contamination from engine bay fluids. Physical damage to mounting brackets is common on used units but typically does not impair the module’s electrical function.
