Is high-pitched coming from under your car?

The most common reasons for there to be high-pitched noises coming from under the hood/bonnet of your Land Rover Defender 110 are having a belt slip (drives accessories like air conditioning, power steering etc) or having a vacuum leak from your air intake hoses being worn or cracked (most common noise when accelerating).
