How to set the horn sound when locking the Volkswagen Tiguan?
2 Answers
Volkswagen Tiguan's locking horn cannot be set by yourself. It can be activated by flashing the ECU or you can go to a 4S store to have it flashed. In the factory settings of Volkswagen models, the horn does not sound by default when the doors are locked. The locking horn sound requires flashing the data (via OBD vehicle system to modify the settings). After enabling this function, hearing the horn sound when locking ensures that the doors are securely locked. Below are specific details about the 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 operational efficiency, power, torque, etc. 3. Information such as air intake, fuel injection, ignition timing corresponding to various engine speeds, gears, loads, temperatures, etc., is recorded in the ECU in a database format, known as "M.A.P." 4. Flashing the ECU essentially involves modifying this "M.A.P." database. Changing the data that controls the engine affects its operation, achieving the desired effects within the engine's tolerable limits. 5. Similar to a computer CPU, which is labeled at 3.0GHz at the factory but can be overclocked (increasing speed) or underclocked (energy saving) within certain limits.
I remember setting the horn beep when locking on the Tiguan requires operation in the infotainment system. After starting the vehicle, open the settings menu to find the vehicle options, then enter the door lock settings module where you'll see the lock confirmation sound switch. Enabling this feature makes the car emit a beep every time you lock it with the remote key - especially useful in noisy environments like shopping mall underground garages. Once I accidentally turned it off and ended up checking my car over a dozen times in the parking lot before feeling safe to leave. Volkswagen's system logic is quite reasonable, though models before 2020 might require enabling this hidden feature using a VCDS diagnostic cable. My friend Lao Wang who now drives an electric vehicle always envies this practical feature of mine, as the locking sound helps prevent accidentally unplugging during charging. I recommend asking the technician to teach you how to adjust it during your next dealership maintenance visit - that's the most reliable way.
