How to Activate the Lock Sound on Volkswagen Tiguan?
2 Answers
It cannot be set by yourself and needs to be activated by flashing the ECU. You can visit a 4S store to have it done. Below is relevant information: 1. Lock sound prompt function In the factory settings of Volkswagen models, the horn does not sound by default when the doors are locked. The lock sound requires flashing the data (OBD vehicle system, modifying settings). After enabling this function, when you hear the horn sound upon locking, you don’t need to worry about the doors not being locked. 2. ECU flashing, currently also known as ECU upgrade, car computer upgrade, or ECU modification in China. The formal translation is actually ECU tuning. How ECU flashing works: It involves rewriting the program to finely adjust the fuel supply and ignition timing based on the original factory data or to unlock hidden functions set by the factory. By optimizing parameter settings, it aims to increase horsepower, enhance torque, or reduce fuel consumption. Increasing horsepower and torque will correspondingly increase fuel consumption, while decreasing horsepower and torque will reduce fuel consumption.
To activate the locking sound on the Volkswagen Tiguan, I'd say it's usually done through the vehicle's settings menu. First, get in the car and start the engine without driving it. Look for the vehicle settings option on the central control screen or dashboard and click into it; then navigate to the door lock or central locking system section to see if there's an option called something like confirmation sound, and check to enable it. Next, after getting out of the car, press the lock button on the remote key to test—you should hear a beep confirming successful locking. This process was straightforward on my 2020 Tiguan, but if you're driving an older model, you might need to visit a 4S shop to activate it using a diagnostic tool, as some cars don't have it enabled by default. I personally like this sound when driving because it prevents me from forgetting to lock the car and losing items, offering peace of mind, especially in crowded parking lots. If there's no response during setup, checking the battery or software updates usually solves the issue.
