High-quality parking assistance control unit designed for first-generation Peugeot 3008 and 5008 models. This ECU manages ultrasonic front and rear sensor inputs to provide accurate distance warnings and automatic parking aid support. Ideal for professional workshops and experienced DIY mechanics searching by OEM numbers (9666663880, 1607733080, 6590KE). Replacing a faulty unit restores correct sensor processing and eliminates false alarms or loss of parking guidance.

Technical Information

• Manufacturer: Stellantis Citroën Peugeot
• Model: PEUGEOT 3008 I, PEUGEOT 5008 I
• Product Codes: 9666663880, 1607733080, 6590KE
• Additional Numbers: 1607733080 | 6590KE | 9666663880

Function

The unit processes signals from front and rear ultrasonic sensors, evaluates obstacle distance, and communicates warnings to the driver via the vehicle display and audible alerts. It also coordinates automatic parking assistance features where fitted. Proper operation depends on intact sensors, wiring harnesses and reliable power/ground connections.

Compatibility And Fitment

Fits first-generation Peugeot 3008 and 5008 models equipped with front and rear parking sensors that use the listed OEM codes. Many customers search by the product numbers above; ensure the part number matches the unit being replaced when preparing the job.

Installation Recommendations

• Always disconnect the vehicle battery before starting work and follow the manufacturer’s removal/installation procedures to avoid damage to electronic modules.
• Locate the unit (typically mounted under the dashboard or in the fuse/ECU area depending on model) and carefully disconnect all connectors and sensor harnesses.
• Inspect connectors and sensor cables for corrosion or damage and repair any wiring faults before installing the replacement unit.
• After mechanical installation clear fault codes and perform system initialization or coding as required. For PSA vehicles, use compatible diagnostic equipment (DiagBox/Lexia/PP2000) to clear errors and verify sensor function.
• Test all parking sensors and parking aid functions on completion in a safe environment.

Replacement Procedure (Summary)

1. Disconnect battery and wait a few minutes to ensure system power-down.
2. Remove necessary trim panels to access the control unit.
3. Unplug sensor harnesses and any connectors attached to the ECU.
4. Replace the unit and reconnect all connectors, ensuring secure and corrosion-free contacts.
5. Reconnect the battery, clear any stored fault codes and perform diagnostic checks.
6. Verify sensor calibration and perform a road test to confirm correct operation.

Why These Units Fail

• Water Ingress And Corrosion: Moisture penetrating connectors or the module housing is a common cause of intermittent faults or total failure.
• Impact Damage: Collisions or strong impacts to bumpers and sensor areas can damage sensors and overload the control unit.
• Electrical Issues: Short circuits, poor grounds or damaged wiring can cause ECU malfunctions or component burnout.
• Sensor Failures: Faulty ultrasonic sensors or wiring can create conditions that make the ECU report errors or disable the parking assist functions.

Notes For Professionals

This part is intended for technicians and experienced DIYers. When replacing, verify connector condition and ensure diagnostic verification after installation. Searching by OEM codes 9666663880, 1607733080 or 6590KE will help locate the correct unit quickly.
