Description
Parking Sensor Bosch For Citroën, Peugeot And DS Vehicles.
Overview
High-quality Bosch parking sensor designed as a direct-fit replacement for Citroën, Peugeot and DS Production Vehicles. This PDC (Park Distance Control) sensor restores reliable object detection at low speeds, assisting drivers during parking maneuvers and tight urban driving. The part is often searched for by its product codes, so please verify the number against your vehicle’s listing.
Key Features
- Genuine Bosch technology for reliable ultrasonic detection and consistent performance.
- Direct-fit design for original mounting points and electrical connections on supported Citroën/Peugeot/DS models.
- Restores full Park Distance Control functionality when replacing a faulty sensor.
- Compact, sealed housing engineered to resist road contaminants and vibration.
Application And Compatibility
Typical fitment includes models such as Citroën C3 Picasso, Citroën C4 Picasso and Citroën C5 X7, as well as a range of Peugeot and DS vehicles using the same PDC system. This sensor is commonly listed under the following numbers and may be searched by those codes:
Technical Information
- Manufacturer: Bosch
- Model: Parking Sensor / PDC Sensor
- Product Codes: 966638215, 0263003587, 96663821577XT
- Additional Numbers: 1611735680, 1611735580
Function
The sensor is an ultrasonic proximity detector used by the vehicle’s Park Distance Control system to measure distance to obstacles behind or in front of the vehicle. It converts reflected sound waves into electrical signals that the PDC control unit interprets to provide audible and visual alerts to the driver.
Replacement Procedure
- Park the vehicle on a level surface, engage the handbrake and, as a safety precaution, disconnect the negative terminal of the battery.
- Access the sensor from the rear or front bumper—this may require removal of the bumper or access panels depending on the model.
- Disconnect the electrical connector and release the sensor from its retaining clip or mounting bracket. Carefully remove the sensor to avoid damaging the bumper or trim.
- Install the replacement sensor in the correct orientation, ensuring the sealing surfaces and clips engage fully. Reconnect the electrical connector and reassemble bumper/trim components.
- Reconnect the battery and perform a PDC system check by engaging reverse gear or using the vehicle’s self-test routine to confirm correct operation.
Installation Recommendations
- Use appropriate trim tools to avoid damaging bumper paint or clips during removal and installation.
- Ensure connector pins and sensor sealing surfaces are clean and free of corrosion or debris before assembly.
- Test the PDC system after installation to confirm the sensor is functioning and properly aligned.
- If multiple sensors are replaced, follow the vehicle manufacturer’s procedures for system calibration if required.
Why The Part Fails Most Often
Parking sensors commonly fail due to mechanical damage from impacts or minor collisions, ingress of water or road salt that corrodes internal electronics, contamination with dirt, ice or heavy adhesive residues, and damage to the wiring harness or connector. Symptoms of a failing sensor include intermittent beeps, constant PDC warnings, or complete loss of detection on the affected sensor.
Additional Notes
This Bosch sensor is a direct replacement option for vehicles equipped with the same PDC hardware and part numbers listed above. Because PDC systems are frequently searched by part number, using the exact product code improves the chance of a correct match.
