Why is my BMW X3 making a strange noise when accelerating?

I just bought a BMW X3 and I've noticed that it's making a strange noise when I accelerate. It almost sounds like a high-pitched whine. Is this normal or should I be worried?

It's always a good idea to pay attention to any unusual noises your car is making. This could be a sign of a potential issue, so it's important to address it before it becomes a bigger problem. I would recommend taking your BMW X3 to a certified mechanic for a diagnosis.

It's possible that the noise you're hearing is just a normal characteristic of the BMW X3's engine. However, it's always better to be safe than sorry. I would recommend taking your car to a BMW dealership for a professional opinion.
