Why is my BWM car's engine making a strange noise?

I have a BWM car and recently the engine has been making a strange noise. It almost sounds like a whirring sound. What could be causing this and should I be worried?

It is possible that there is an issue with the bearings in your engine. I recommend taking your car to a trusted mechanic to have it checked out.

Another possibility could be that your car's fan belt is worn or loose. This can cause unusual noises in the engine. I suggest getting it looked at by a professional as soon as possible.
