Mercedes W415 Speaker PDC Parking Distance Buzzer Alarm Sensor 256506024R

Mercedes W415 Speaker PDC Parking Distance Buzzer Alarm Sensor is an original parking assistance system component responsible for generating the PDC system audible signal in Mercedes vehicles. The acoustic sensor works with the vehicle's factory electronics, informing the driver about approaching obstacles during maneuvering. This practical solution improves daily driving comfort and increases safety when parking in tight spaces.

Function and application in the PDC system

The presented PDC speaker acts as the final warning element in the Parking Sensors system, converting signals from the control module into clear audible alerts. This provides the driver with readable information about the distance to obstacles, facilitating precise maneuvering both in reverse and when moving forward. Using a dedicated buzzer instead of universal solutions ensures the consistency of the entire system's operation as well as the correct volume and frequency of the signal.

Compatibility and integration with Mercedes electronics

The PDC speaker is designed to work with factory controllers and wiring harnesses used in Mercedes W415 series models. This ensures correct communication with the vehicle's diagnostic system, proper sensor status recognition, and eliminates the need for additional adapters or wiring modifications. The original design ensures stable mounting in the location intended by the manufacturer and proper vibration damping, which translates into a clear, repeatable warning signal.

Benefits of using an original used component

Using an original, used PDC buzzer allows you to maintain the factory characteristics of the parking assistance system while optimizing repair costs. Compared to replacements with uncertain parameters, such a component offers predictable behavior in the system, the correct signal volume, and compatibility with the vehicle's software. It is a sensible solution for users who want to restore full functionality to the parking system without interfering with the car's original electrical architecture.

Practical installation and operating tips

When replacing the PDC speaker, it is worth paying attention to the condition of the electrical connectors and the correct routing of the wiring to avoid future system interference. It is recommended to perform a system test after installation – both in reverse gear and when activating the sensors from the cockpit, if the vehicle has such a function. A properly functioning buzzer should generate an increasing audible signal as the distance to the obstacle decreases, without any interruptions or dropouts.
