Purpose and Function in the Vehicle

The presented sensor is a component of the parking assistance system mounted in the rear bumper of the Audi A3 8P. It is responsible for precisely detecting obstacles behind the vehicle and transmitting signals to the control unit and the acoustic or visual system. A properly functioning rear sensor increases maneuvering safety, reduces the risk of minor collisions, and facilitates daily use of the car in tight spaces.

Color and Visual Match

The part is finished in Ice Silver Metallic - X7W, allowing for a seamless match with bumpers painted in the same shade. This ensures that after installation, the sensor does not visually stand out from the bumper surface, maintaining the factory appearance of the rear of the vehicle. This is particularly important for post-accident repairs and for maintaining the aesthetics of a premium car like an Audi.

Technical Characteristics and System Integration

The sensor belongs to the Parking Sensors group and is designed for the rear of the vehicle. The manufacturer's design allows for:

• correct seating in the bumper socket without modifying mounting points,
• connection to the factory wiring harness,
• compatibility with the original Audi parking system control unit.

This solution minimizes the risk of installation errors and compatibility issues, and also simplifies diagnostics in case of future servicing needs.

Condition, Origin, and Benefits of Choosing a Used Sensor

The offered sensor is a used part, sourced from dismantling, which allows for a reasonable repair cost while maintaining the original manufacturer's specifications. In practice, this means:

• factory fit for the Audi installation,
• maintenance of operating parameters consistent with the vehicle's system,
• economical replacement of a single component without the need for system modifications.

For many users, this is a rational choice for repairing the parking system – especially when they prioritize an original component over a replacement with uncertain parameters.

Selection by Part Numbers and Technical Support

This sensor has a dedicated OEM part number and related interchangeable numbers, which facilitates unambiguous identification and selection for a specific Audi A3 8P model. If you have doubts about matching it to your car's configuration (year, trim level, type of parking system), it is advisable to consult manufacturer catalogs or specialist support to avoid compatibility issues.
