I encounter noises from serpentine belt BMW X5
The best strategy to control the state of your belts is to listen to your car. As soon as you recognise noises such as squealing or bells, you should take a closer look to examine their source. The function of the serpentine belt or driving belt of your BMW X5 is to transfer the movement of the engine to the secondary elements that it will supply with energy. Like steering, air conditioning, water pump. Its role is therefore essential in the normal performance of your car. The serpentine belt is said to be asynchronous, i.e. unlike the timing belt, it has the ability to drive distinctive engine elements at variable speeds.

This sort of squealing belt noises on BMW X5, which will often be acute, can commonly arise when the engine is cold, or when the acceleration increases in intensity. . This sort of sound must be heavy and it is obviously quite simple to connect it with one of these belts. To examine, do not hesitate to open your bonnet, engine running cold and check the source of this noise, the serpentine or driving belt being apparent, it should not be too complicated for you to identify a belt noise on your BMW X5. The reason of this issue can be connected to the damper pulley, which works as a damper to eradicate irregularities in the tension in the motor cycle and therefore in the energy transmission to the belt. This results in a loose belt that will jerk. However, you still have the opportunity that this phenomenon is annodine. As the serpentine belt of your BMW X5 is exposed, it may squeak due to excessive humidity due to weather conditions and it may end with a change in conditions.

Make sure to examine first the serpentine/driving belt which in most cases is the reason of this issue, otherwise it will be necessary to replace the tensioner or pulley.
I perceive bearing noises on the serpentine belt of my BMW X5
Finally, if in your case you discern a bearing belt noise on BMW X5, it is plausible that it is connected to a serpentine belt that is too tight . Indeed, it is plausible that its size may be smaller than recommended and cause the entire system to overvoltage, resulting in this whistling noise or slight rolling noise. The risk in this case is that the bearing bearings or the Damper pulley may fail . Remember, therefore, to stretch the belt to limit the risks or to change it if it is too short. If after checking all thoses possibilities, you still detect a belt noises, read our article about timing belt noises on BMW X5 which could maybe help you.
