Description
Electronic parking brake switch for Citroën C4 Picasso up to 2013, DS4 and Peugeot 3008, 5008. Used part, shows signs of use, fully functional.
This genuine OEM electronic parking brake (EPB) switch is a direct fit for a range of Stellantis vehicles and is commonly searched by part number for fast identification. Designed for professional workshops and skilled DIYers, the unit provides reliable control of the electric parking brake mechanism and restores normal operation in cars where the original switch is damaged or worn. Ideal when the original button is cracked, unresponsive or shows intermittent function, this switch brings back tactile feedback and correct EPB command signals to the vehicle control system.
Technical Information
- Manufacturer: Stellantis (Citroën / Peugeot)
- Model: Citroën C4 Picasso (up to 2013), DS4, Peugeot 3008 I, Peugeot 5008 I
- Product Codes: 9666405677, 470706, 470703
- Other Numbers: 470706 (reference), 470703 (alternate reference)
Fitment And Function
The switch mounts in the center console and sends electrical pulses to the EPB control system to engage or release the parking brake. In normal operation the driver presses or releases the switch to command the EPB motor/actuator. Symptoms indicating a faulty switch include inability to engage/disengage the parking brake, illuminated EPB warning light, or intermittent operation requiring multiple presses.
Installation Recommendations
- Always disconnect the vehicle battery before starting work to avoid short circuits or damage to vehicle electronics.
- Remove the center console trim panels carefully to access the switch. Use trim tools to avoid damaging clips and surrounding plastic.
- Unplug the electrical connector and remove the retaining screws or clips holding the switch in place. Replace with the new unit and ensure the connector is fully seated and locked.
- Reassemble trim and reconnect the battery. Perform a function test: operate the parking brake several times and verify indicator behavior on the instrument cluster.
- If The Vehicle Displays EPB Faults After Replacement: Some vehicles require an EPB initialization or calibration using a diagnostic tool compatible with PSA/Stellantis systems (for example DiagBox). If initialization is required, perform it with proper diagnostic equipment or have it completed by a qualified workshop.
- Follow manufacturer service procedures and torque specifications where applicable to avoid damage during reassembly.
Why This Part Most Commonly Fails
Failure of the EPB switch is usually caused by mechanical wear of the switch mechanism, degraded internal contacts, or contamination from spilled liquids and dirt getting into the console. Repeated heavy use, brittle plastics from age, and connector corrosion can also lead to intermittent or permanent loss of function. In some cases, what appears to be a switch fault is actually an issue with wiring, connectors or the EPB actuator/control unit, so inspect related components during replacement.
This used unit has visible signs of prior use but is fully functional. If you rely on accurate part matching, use the product codes listed above when searching or ordering to ensure correct fitment.
