Who Should Buy
This part is intended for professional mechanics and knowledgeable DIY enthusiasts performing dashboard or steering-column repairs on Citroën/Peugeot vehicles. It is especially useful when troubleshooting intermittent Start-Stop failures, unresponsive buttons, or when replacing damaged switch housings during interior repairs.
How The Part Works
The Start-Stop switch controller provides the user-input for the engine management and body control modules to engage or disable the automatic start-stop sequence. When pressed or actuated, the switch sends a signal to the vehicle’s control systems indicating the driver’s intent, which the ECU and comfort module interpret according to current vehicle conditions (battery charge, engine temperature, door status, etc.).
Replacement Procedure (Overview)
Recommended for technicians and experienced DIY mechanics. Typical replacement steps:
- Disconnect the negative battery terminal before starting work to prevent short circuits and accidental airbag deployment.
- Remove the relevant trim panels around the center console or steering column to access the switch assembly.
- Unplug the electrical connector(s) from the switch—note connector locking tabs and orientation.
- Release the switch retaining clips or screws and remove the defective unit from the dashboard aperture.
- Install the new switch in reverse order, ensuring connectors are fully seated and clips engage.
- Reconnect the battery and verify Start-Stop operation. Check for any dashboard fault codes and clear if required.
Most Common Causes Of Failure
– Wear and contamination: Frequent use, spilled liquids, or accumulated dust can cause contact faults or sticking mechanisms.
– Electrical contact degradation: Oxidation or broken solder joints may lead to intermittent signals.
– Mechanical damage: Impact or forceful removal of trim can physically damage the switch housing or actuator.
– Related system issues: Sometimes apparent switch faults are caused by low battery voltage, faulty sensors, or control module errors—diagnose electrical supply and communication lines if replacement does not restore function.

Installation Recommendations
– Always disconnect the battery before starting the job and follow the vehicle manufacturer’s disassembly procedures to avoid damaging trim and connectors.
– Use appropriate panel tools to prevent breaking clips and plastic retainers.
– After installation, verify function under different vehicle conditions (engine running, engine off, different battery charge states) to ensure the Start-Stop logic communicates correctly with vehicle modules.
– If fault codes persist after replacement, perform a full electrical check of supply, ground, and communication lines and scan for related body or engine control module errors.
Why This Part Is Often Sought By Part Number
Start-Stop controllers are commonly searched by original part number (96671871XT) because exterior appearance and connector variants can be similar across model years. Using the OE number speeds up identification and ensures fitment of the correct switch variant for dashboard trim and electrical harness compatibility.
Replace a faulty Start-Stop switch with a correct-fit unit to restore reliable system operation and avoid nuisance faults. Ideal for workshops and technically competent car owners performing targeted interior repairs.
