Application and vehicle function

The presented component belongs to the Parking sensors group and is intended for installation in the front bumper area. It operates as part of the PDC system, which monitors the space in front of the vehicle, transmitting a signal to the control unit and the driver warning system. A correctly selected sensor ensures:

• accurate obstacle detection in the front area,
• proper compatibility with factory Mercedes electronics,
• maintenance of factory parking assistant functionality.

Compatibility with Mercedes W207 / W212

The Mercedes W207 W212 PDC Parking Distance Sensor Front Cavansite Blue has been developed for integration with the factory parking system in these models. Thanks to the use of original housing geometry and the correct connector type, the sensor is ready for installation in the location provided by the manufacturer, without the need for installation modifications.

The Cavansite Blue Metallic - 890 color allows for aesthetic integration of the component into the body paint, which is particularly important when replacing a single sensor in an already painted bumper.

Technical characteristics and condition

The offered sensor is an original solution used by Mercedes in PDC systems. The construction is adapted for operation in external conditions – in an area exposed to moisture, temperature changes, and road debris. The item is in used condition, meaning it has been removed from a vehicle and is intended for further use after proper installation.

Before installation, it is recommended to:

• verify proper operation in conjunction with the vehicle's electrical system,
• check the electrical socket for cleanliness and stable contact,
• inspect the bumper mounting to ensure the correct operating position.

Benefits of using an original PDC sensor

Using a dedicated parking sensor in a color matched to the body allows for maintaining visual consistency and proper operation of the parking assistance system. In practice, this means:

• stable distance readings and no random system errors,
• no need for adapting universal solutions,
• easier diagnostics in case of potential PDC faults.
