It is highly plausible that this is a minor issue, but before being sure, it is better to execute some inspections. If this belt noise comes from your serpentine or driving belt, our team has written a post to support you finding and repairing it. First, we will look at the serpentine belt noises on your BMW X4 and then we will take a look at the sources of these sounds.
I encounter noises from serpentine belt BMW X4
The best method to control the state of your belts is to listen to your vehicle. Immediately after you find sounds such as squealing or bells, you should take a closer look to examine their origin. The role of the serpentine belt or driving belt of your BMW X4 is to transfer the movement of the engine to the secondary components that it will supply with energy. Like steering, air conditioning, water pump. Its role is therefore important in the normal functionality of your vehicle. The serpentine belt is said to be asynchronous, i.e. unlike the timing belt, it has the capacity to drive different engine components at variable speeds.
I find out squealing noises on my serpentine belt BMW X4
This sort of squealing belt noises on BMW X4, which will often be acute, can mostly occur when the engine is cold, or when the acceleration increases in intensity. . This sort of noise must be heavy and it is normally quite simple to link it with one of these belts. To examine, do not hesitate to open your bonnet, engine running cold and check the origin of this noise, the serpentine or driving belt being exposed, it should not be too complicated for you to spot a belt noise on your BMW X4. The cause of this issue can be connected to the damper pulley, which acts as a damper to get rid of 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 event is annodine. As the serpentine belt of your BMW X4 is exposed, it may squeak due to excessive humidity due to weather conditions and it may end with a change in conditions. Keep in mind to examine the state of your belt (crack, crack), if this is the case replace it, otherwise simply tighten the belt.
I find out loud serpentine or driving belt noises BMW X4

It is therefore important that you look further and find the cause for this sound that can indicate the end of your belt’s life. Like squealing noise, it can be identified in most cases when cold . It generally means a worn pulley whose streaks no longer allow it to be driven properly. Other alternatives, the dynamic belt tensioner or the disengageable pulley of the alternator may be at the origin of this issue. Don’t forget to examine first the serpentine/driving belt which in most cases is the cause of this issue, otherwise it will be necessary to replace the tensioner or pulley.
I find out bearing noises on the serpentine belt of my BMW X4
Finally, if in your case you discern a bearing belt noise on BMW X4, 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 suggested 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 replace it if it is too short. If after checking all thoses alternatives, you still notice a belt noises, read our article about timing belt noises on BMW X4 which could maybe help you.
