Why is there no sound when locking the Lavida Plus 2021?
2 Answers
The Lavida Plus 2021 does not make a sound when locking because the feature is not activated. Tutorial to enable the horn sound when locking the Lavida Plus: 1. Press the brake pedal, shift the gear lever to P position, and release the brake pedal. 2. Press the one-touch start button twice in succession, and close all doors. 3. Hold down the lock button on the driver's door for more than 10 seconds without releasing. Working principle of the Lavida's locking horn sound: 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 internal electromagnet of the horn to operate, making the diaphragm vibrate and produce sound.
As an experienced car repair enthusiast, let me talk about the issue of the 2021 Lavida Plus not making a sound when locking. This is quite common and usually a setting problem: many vehicles default to turning off the alert sound to reduce environmental noise. You can check the central control system settings, enter the vehicle security or locking menu, and manually turn on the sound option. If holding down the lock button on the remote key doesn't produce any sound either, it might be due to low battery power or the software needing an update. Another reason could be hardware failure, such as a broken horn or a short circuit in the wiring, which would cause the system to mute. I recommend starting with simple troubleshooting: ensure all doors are tightly closed and visit a 4S shop for diagnostics. The locking sound isn't just about convenience; it confirms that the car is securely locked, reducing the risk of theft. In terms of design, Volkswagen emphasizes quietness to comply with urban regulations, but users can adjust this through settings. If it's a new car that just doesn't make a sound when bought, consult the manual to find the activation method—don't worry about major issues.
