Why did the Mercedes-Benz locking sound suddenly become quieter?
2 Answers
The reason why the Mercedes-Benz locking sound suddenly becomes quieter is due to insufficient battery power or poor horn contact. More information about Mercedes-Benz is as follows: 1. Brand Introduction: Mercedes-Benz is a German automotive brand renowned for luxury and high performance, headquartered in Stuttgart, Germany. Its product lineup includes various passenger cars and medium to large commercial vehicles. Mercedes-Benz is one of the members under the Daimler AG. 2. Competitors: Initially, it mainly focused on the Mercedes-Benz S-Class (launched in 1886), which is the car with the longest wheelbase in the Mercedes-Benz sedan lineup, with main competitors being the BMW 7 Series, Jaguar XJ, and Audi A8. After World War II (in 1947), the Mercedes-Benz E-Class was introduced, with main competitors being the BMW 5 Series, Audi A6, and Jaguar XF.
Recently, the locking sound of my Mercedes-Benz has become quieter, and I’ve encountered a similar issue before. It took me quite a while to figure it out. Generally, if the horn sound when locking the car becomes softer, it might be because the volume setting was accidentally lowered. In Mercedes-Benz vehicles, there’s a 'Locking Reminder' option in the vehicle settings on the central control screen. You can adjust the sound level there—sometimes misoperations or system updates may reset these values. Additionally, low battery in the car key can also affect signal strength, leading to a weaker sound, so try replacing the battery. Environmental factors like noise interference in underground garages can make the sound seem even quieter; in such cases, closing the windows and locking the car can help verify the issue. I suggest first adjusting the settings or restarting the system. If that doesn’t work, check the hardware components, as a sound that’s too soft can make it hard to confirm the locking status, potentially leading to mistakenly thinking the car isn’t locked and posing a property risk. During regular maintenance, remember to ask the technician to inspect this function to prevent minor issues from escalating.
