Hello guys, this issue is for my 2008 cmax 1.8 petrol 125hp zetec.
I've noticed that when I put my foot on the accelerator, I get this constant humming noise. Noise sounds something similar to a failing power steering pump which I don't have as this car is fitted with the electric powers steering. You only hear the noise when you touch the accelerator, if you lift your foot off whilst the car is moving, the noise disappears straight away.
Things I've checked is the belt (which is fine) and had a mechanic look at the wheel bearing (which is also fine).
Read somewhere that this could be a crack on the breather pipe but I don't know how to check this.

Would appreciate any help or other suggestions on what the cause might be.

If it's a bearing humming kind of noise could it be the alternator or the belt tensioner bearings?
or try putting the clutch pedal down to see if it's clutch release bearing?
