The reason of this problem can be linked 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 an opportunity that this event is annodine. As the serpentine belt of your Bmw Z4 is exposed, it may squeak due to excessive humidity due to weather conditions and it may end with a change in conditions.

I discover bearing noises on the serpentine belt of my Bmw Z4
Finally, if in your case you recognize a bearing belt noise on Bmw Z4, it is conceivable that it is linked to a serpentine belt that is too tight . Indeed, it is conceivable that its size may be smaller than prescribed and cause the entire system to overvoltage, resulting in this whistling noise or slight rolling noise. The problem 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 alternatives, you still perceive a belt noises, read our article about timing belt noises on Bmw Z4 which could maybe help you.
