How to set the horn sound when locking the Volkswagen Teramont?

Volkswagen Teramont's lock horn sound cannot be set manually and needs to be activated by flashing the ECU. The details are as follows: 1. Lock confirmation sound function: In the factory settings of Volkswagen models, the horn does not sound when the doors are locked by default. 2. The lock horn sound requires flashing the data (via OBD vehicle system to change settings). After enabling this function, you will hear the horn sound when locking the car. Below is the principle of ECU: 1. The operation of a car engine is controlled by the car's computer (i.e., ECU). 2. The ECU controls the engine's air intake, fuel injection, ignition timing, etc., thereby determining the engine's operating efficiency, power, torque, etc. 3. The data corresponding to the engine's operation under various conditions such as speed, gear, load, and temperature, including air intake, fuel injection, and ignition timing, are recorded in the ECU in the form of a database, known as MPA. 4. Flashing the ECU essentially involves modifying this MPA to alter the data controlling the engine, affecting the engine's operation, and achieving the desired effect within the engine's tolerable range.
I've been driving the Volkswagen Teramont for two years, and adjusting the horn sound when locking is quite simple. I usually use the remote key to operate: sit in the car with the doors closed, make sure the key is in hand, then quickly press the lock button (the one with the car icon) twice in succession. At this point, the horn sound will automatically switch, with possible modes including loud, soft, or silent. If there's no response, it might be a system setting issue. Try starting the vehicle and then navigate to the main menu on the infotainment screen, select 'Vehicle Settings,' and look for the 'Door Locks' or 'Sounds' options to adjust the locking confirmation sound. I use this feature because it gives me peace of mind to hear the confirmation, especially in crowded places where I don't want to risk leaving the car unlocked and vulnerable to theft. However, if multiple attempts fail, it's advisable to check the user manual or visit a 4S shop for professional diagnostics. Some model versions may require a software update to enable this feature. In any case, take it step by step and don't rush—safety first.
