Description
Parking sensor Bosch for Citroën and Peugeot vehicles. It is from Citroën C5 X7.
Description
High-quality Bosch parking (PDC) sensor designed for Citroën and Peugeot passenger cars. This ultrasonic proximity sensor is a direct-fit replacement commonly found on rear and front bumpers of Stellantis models. Ideal for professional workshops and experienced DIY mechanics, the sensor restores reliable object detection for parking assistance systems and eliminates audible or visual faults caused by damaged or non-responsive sensors.

Compatibility
Compatible with a range of Citroën and Peugeot vehicles that use Bosch PDC sensors. Known applications include Citroën C5 X7 and Citroën C3 Picasso; the sensor may also fit other models sharing the same part numbers. Buyers often search by part number (e.g., 0263003587, 966638215) to confirm fitment.
How It Works
The sensor emits ultrasonic pulses and measures the time delay of returning echoes to determine the distance to nearby obstacles. The sensor communicates with the vehicle’s parking control module to trigger warnings (audible beeps and dashboard indicators). Proper mounting and correct connector seating are essential for accurate operation.
Replacement Procedure
- Switch off ignition and remove the key. For safety, disconnect the negative battery terminal if you will be working extensively with the wiring harness.
- Access the sensor through the bumper cover or the vehicle’s service opening—some models require partial bumper removal.
- Depress the retaining clip and gently push the sensor out from the inside of the bumper.
- Disconnect the electrical connector and inspect for corrosion or damaged pins.
- Fit the new sensor in the correct orientation, snap it into the bumper opening, and reconnect the plug.
- Reassemble any removed panels, reconnect the battery (if disconnected), then run a system check with a diagnostic tool and clear any stored PDC error codes.
Installation Recommendations
Ensure the sensor is the correct part number for the vehicle and that the mounting aperture is clean and free of debris. Avoid touching the sensing face with sharp tools or solvents. After installation, test the sensor operation at low speed and perform a diagnostic scan to confirm the parking system recognizes the new unit. If the vehicle reports multiple sensors faulty, inspect wiring and the PDC control module before replacing additional sensors.
Most Common Failure Causes
- Physical Impact: Bumper collisions and minor knocks can crack the sensor or displace its mounting, causing intermittent or complete failure.
- Moisture Ingress and Corrosion: Damaged seals or corroded connector pins lead to electrical faults and signal loss.
- Wiring Damage: Chafed wiring or connector damage from previous repairs can interrupt communication with the control module.
- Contamination: Road grime, salt, or heavy buildup on the sensing face degrades performance and range.
Notes for Buyers
Search by the listed part numbers to find the exact match for your vehicle. The sensor is a commonly replaced PDC component; keeping the correct part number to hand speeds up ordering and installation. Suitable for workshops and experienced DIY mechanics familiar with parking system diagnostics.
