Is the Volkswagen Lock Sound a Hidden Feature?

[Alexander]

Volkswagen lock sound needs to be activated at the 4S shop by enabling the 5030 Volkswagen hidden function. Below are the specific details about car horns: 1. Function of Car Horns: The horn is the audio signal device of a car. During driving, the driver can emit necessary audio signals as needed and in accordance with regulations to warn pedestrians and alert other vehicles, ensuring traffic safety. It is also used for urging and signaling. 2. Working Principle: The sound is produced by the vibration of a metal diaphragm using the airflow of compressed air. Therefore, it can only be used in vehicles equipped with an air compressor. Generally, it is installed in large buses and heavy-duty trucks, especially for long-distance transport vehicles driving in mountainous areas or curves, where honking can effectively alert pedestrians and drivers of oncoming vehicles.
