What Causes the Constant Beeping of BMW Front Radar?
1 Answers
Here are the reasons why the BMW front radar keeps beeping: License Plate Issues: Especially for the front radar, since it generally requires a wide detection range, the radar's ultrasonic waves are also fan-shaped. If the license plate frame is too large or the license plate is bent or deformed, it may enter the radar's detection range, causing false alarms and constant beeping. For this issue, we can remove the license plate frame, install the license plate separately, or go to a 4S shop to reset the license plate frame width using a diagnostic tool. If the license plate is deformed, restore it to a flat state before reinstalling. Additionally, it's best to install the license plate with a curvature similar to that of the bumper, ensuring it fits snugly against the bumper. Once properly fixed, it generally won't beep unnecessarily. This problem usually occurs with new cars or vehicles that have had their license plates reinstalled. Dirty Radar Sensor: This is also quite common. For example, after washing the car or driving on muddy roads in rainy weather, mud or rainwater may be detected by the radar on the bumper or directly cover the radar sensor. In winter, rainwater may freeze on the bumper or sensor. Even a small bee flying by could trigger an alarm.
