Why does the Audi A4L alarm go off for no reason?
1 Answers
The reasons why the Audi A4L alarm goes off for no reason are: 1. Alarm sounds after locking the car: After parking, if the main driver's door, passenger door, two rear doors, front hood lock, or trunk lock are not properly closed or if the lock switch is damaged, it can cause poor contact, leading the vehicle's alarm system to activate after turning off the engine and locking the car. 2. Sounds inside the car: Since the Audi A4L is equipped with an ultrasonic alarm function inside the car, as long as the vehicle is locked and ultrasonic waves or sounds are detected inside, the car will automatically sound the alarm. For example, after getting out of the car, if there are children, pets, or even flies or mosquitoes inside, the vehicle will emit an alarm sound.
