Purpose and function of the horn

The presented horn is a component of the warning system responsible for generating a clear acoustic signal when the steering wheel button is pressed or the alarm is activated. Thanks to its OEM-compliant design, the correct volume, sound characteristics, and compatibility with the factory wiring harness in the Mercedes Citan W415 series are maintained.

Using the original horn in this model allows for compliance with the vehicle manufacturer's requirements regarding active safety and operational comfort, without the need for modifications to the installation or the use of additional adapters.

Benefits of using an original horn

Using a factory horn in a Mercedes Citan provides a number of practical technical benefits:

• secure fitment to factory mounting points and electrical connectors,
• maintenance of the correct volume level and sound timbre,
• proper cooperation with the vehicle's alarm system,
• reduction of the risk of installation errors resulting from the assembly of universal replacements.

This used OEM component is a solution that allows you to combine functionality with reasonable repair costs, while maintaining consistency with the vehicle's factory configuration.

Condition of the component and service application

The offered horn comes from disassembly and is intended for reinstallation in a vehicle after prior verification of compatibility with a specific equipment version. This type of component is particularly useful in situations where the existing horn has suffered mechanical damage, corrosion, or has stopped generating the correct sound.

Choosing the original horn from this offer facilitates workshop work, shortens repair time, and avoids problems with matching electrical and acoustic parameters to the system used in the Mercedes Citan.
