How to Set the Locking Horn for the New Bora?

[AuroraLynn]

The locking sound prompt is a feature that is turned off by default in Volkswagen factory settings. To enable it, you need to use a maintenance computer to access the central electrical system and modify the coding of the body control unit. Here is some information about the horn: 1. The horn is the audio signal device of a car. During driving, the driver can emit necessary audio signals as needed and required, to warn pedestrians and alert other vehicles, ensuring traffic safety. It is also used for urging movement and transmitting signals. 2. Working principle: When the horn button on the steering wheel or other locations is pressed, current from the battery flows through the circuit to the electromagnetic coil of the horn relay. The electromagnetic coil attracts the moving contact switch of the relay to close, allowing current to flow to the horn. The current causes the electromagnet inside the horn to work, thus making the diaphragm vibrate and produce sound.
