I recently noticed that my BMW Z4's engine is making strange noises. It's a high-pitched whirring sound that occurs when I accelerate. The noise seems to go away when the car is idling. What could be causing this issue and how can I fix it?
ReplyHi Tiffany, it sounds like your BMW Z4 may have a problem with the serpentine belt. If the belt is worn or damaged, it can create a high-pitched noise when the engine is under load. I would recommend getting it checked by a mechanic and replacing the belt if necessary.
