Accelerating Noise

I drive a nine-month 0ld Myvi Automatic. Recently an intermittent noise has developed, and this sound only occurs when I accelerate. It sounds like a fainy metallic whirring noise. I am unable to diagnose the problem, as it does not occur frequently or long enough for the mechanic to listen to it. Otherwise, the car perform normally. Have you ever come across this problem or noise?

Based on you information, it is difficult to give you any pointers because it is not clear when this noise occurs and under what circumstances. For example, does the noise occur when you are at low speeds and in top gear or in low gear at high speeds? My feeling is that the problem is in the engine compartment and frankly even technician at the service centre may not be able to pin it down unless he can drive the car under the same conditions to replicate the sound.
