Description
BSM R09 DELPHI Unit For Citroën And Peugeot Vehicles. This Is A Used Part With A Guarantee Of Functionality. Some Mounting Brackets May Be Damaged — This Does Not Affect Functionality.
The BSM R09 Delphi is a body system module commonly fitted to a range of Citroën and Peugeot models. It centralises fuses and relays, controls a set of vehicle electrical circuits (lighting, wipers, indicators, central locking feeds and related protections) and serves as a distribution and protection hub in the engine bay. Supplied here as a tested used unit with guaranteed functionality, it is an economical replacement for workshops and experienced DIY mechanics seeking a direct-fit module identified by OE numbers such as 9667199780.
Technical Information
- Manufacturer: Delphi
- Model: Citroën / Peugeot (see compatibility list)
- Product Codes: 9667199780; 6500HV; 6500HW
- Additional Numbers: BSM R09
Compatibility
Typical applications include Citroën C3, Citroën C3 II, DS3 and Peugeot 207. Use the OE/product code (9667199780, 6500HV, 6500HW) to match the unit to the vehicle equipment level and build period.
Function And Common Symptoms
The BSM acts as a fused distribution center and relay carrier for a number of electrical systems. When the module degrades or fails, common symptoms include intermittent or total loss of external lights, wipers not operating, failure of central locking circuits, blown fuses, or multiple unrelated electrical faults that point to a central power distribution issue rather than individual component failure.
Why This Part Fails
Most failures are related to environmental and mechanical causes: water ingress or condensation in the engine bay, corrosion on relay and connector pins, thermal stress from repeated heating/cooling cycles, or mechanical damage from impacts and broken mounting brackets. Overcurrent events and poor fuse/relay contacts can also accelerate wear. Note: Minor damage to plastic mounting brackets is cosmetic and does not affect electrical performance.
Replacement And Installation Recommendations
Safe and correct installation improves reliability. Recommended steps for experienced mechanics or trained DIYers:
- Disconnect the negative battery terminal before starting work to avoid short circuits and protect vehicle electronics.
- Access the module (usually located in the engine bay under a protective cover), remove securing bolts and carefully unplug the multi-pin connectors using the correct release tabs.
- Inspect wiring harness connectors for corrosion or bent pins; clean or repair connectors as required before fitting the replacement unit.
- Fit the replacement BSM, secure all fasteners to the manufacturer’s torque settings, reconnect connectors and re-fit covers.
- Reconnect the battery and verify circuit functionality. Replace any blown fuses with the correct rating only.
For complex electrical diagnostics, or where multiple systems remain inoperative after replacement, use professional diagnostic equipment to identify residual faults and verify power/ground circuits.
Why Choose This Unit
This BSM R09 Delphi unit with OE reference 9667199780 is a cost-efficient solution for workshops and competent DIYers who need a direct replacement for affected Citroën and Peugeot models. The unit is supplied with a guarantee of functionality and has been inspected to ensure connectors and internal functions operate as expected; minor external bracket damage does not affect its performance.
