Description
Parking sensor BOSCH for Citroën and Peugeot. It is from Citroën C5 II.
This Bosch parking sensor is a direct-fit PDC (Park Distance Control) sensor originally used on Citroën C5 II. Suitable for professional workshops and experienced DIYers, the unit is commonly searched by OE and Bosch part numbers (0263003246, 9649614177, 6590A5). It restores ultrasonic obstacle detection to the original specification, ensuring accurate distance warnings when reversing or maneuvering at low speeds.
Designed to meet OE mounting and electrical characteristics, this sensor delivers reliable detection of obstacles and integrates with the vehicle’s parking aid control unit. Typical applications include rear bumper installations where the sensor plugs into the original harness and seats into the factory bumper cutout or mounting bracket.

Installation Recommendations
Replacement is straightforward for a trained technician or experienced DIYer. Typical steps:
- Remove Rear Bumper Trim Or Access Panel To Reach Sensor Housing.
- Disconnect Electrical Connector From Sensor And Release Any Retaining Clip.
- Carefully Push Sensor Out From The Bumper From Inside The Vehicle Or Remove Mounting Bracket If Present.
- Install New Sensor By Pressing It Into The Bumper Until Secure And Reattach Retaining Clip.
- Reconnect Electrical Connector And Reassemble Bumper Trim Or Panels.
- Verify Operation Using The Vehicle’s Parking Assist System And Clear Any Stored Fault Codes If Required.
Why This Part Fails
Parking sensors typically do not have a scheduled replacement interval. Failures commonly occur due to:
- Moisture Ingress Causing Internal Corrosion Or Short Circuits.
- Physical Damage From Impacts Or Scratches To The Sensor Face.
- Connector Corrosion Or Loose Electrical Connections.
- Damage To Wiring Harness During Bumper Removal Or From Road Debris.
- Contamination On Sensor Surface That Impairs Ultrasonic Signals (Dirt, Ice, Heavy Buildup).
When a sensor fails, the parking aid may report a permanent fault, intermittent operation, or display incorrect distance warnings. Replacing the faulty sensor and ensuring clean mounting and secure electrical connections usually restores correct function.
If You Are Searching By Part Number, This Unit Matches The Listed Codes And Is Suited For Workshop Replacement Or A DIY Project When You Have Basic Tools And Access To The Rear Bumper Area.
