Audi honks its horn in double flashes for no reason. What should I do if the Audi suddenly rings in double flashes?

Nowadays, the technology of burglar alarm is becoming more and more mature, and cost control is no longer a difficult thing, while car alarm has become a necessary equipment for every car owner. Audi's double flashing whistle for no reason is because the anti-theft alarm function of the vehicle has been started. After the Audi vehicle is locked, the anti-theft alarm function will automatically turn on and enter the alert state. If someone knocks on the door, pry the door, etc., the anti-theft alarm system will control the vehicle to double-flash the horn, disconnect the circuit and oil circuit, and send a short message to inform the owner, so the vehicle will not be able to start because of this anti-theft alarm system. What should I do if the Audi car suddenly flashes and clicks? 1. Check whether the trunk door lock, hood door lock, door and sunroof are not locked properly. After the vehicle is locked, it will start the anti-theft function. If it is not locked, it will trigger the anti-theft function, so that the Audi car suddenly appears double flashing and ringing. Just lock the trunk door lock, engine compartment lid door lock, door and skylight; 2. One or more lock block switches of trunk door lock, hood door lock, door and skylight have poor contact and damage problems, which will trigger the anti-theft alarm system to start after the vehicle is locked, so it is necessary to go to a 4s shop or a repair shop to find professional personnel for repair or replacement; 3. The monitoring alarm function is installed inside the vehicle, and the function fails. After the car is locked, the internal monitoring and alarm function also monitors the interior of the car, and if it is detected that something moves inside, it will trigger the alarm function. However, if the internal monitoring and alarm function fails, there will be no object moving inside and the alarm function will be triggered. The owner needs to go to the 4s shop or repair shop to find professional personnel to repair or replace it. If the owner's anti-theft alarm system is damaged and keeps flashing, you can consider finding the fuse box of the vehicle, usually in the engine compartment or under the steering wheel. Then find the fuse of the alarm from the fuse box, and use a special tool to remove the fuse of the alarm to contact the alarm. You can also find the location of the alarm according to the automobile operation manual given by the manufacturer, and then manually turn off the alarm to contact the alarm.
