Help - Anyone else have these noises?

Having owned the cars for a few weeks now and finally being able to drive it in the last week, two things are bugging me. First there is a whistle when the car is is stationary, seems like a air is escaping or something (as shown in the vid). I have looked around on the forum and people seem to have noises relating to the fuel pump or something. Think this is different though.

Secondly after i press the accelerator when stationary and moving, there is a slight delay and then another whistle like something to do with the a/c or something, but it happens if the ac is on and off. From my searches the AC tends to make a noise, but not like this. This is shown in the later part of the video.

As i said im am still new to the car and was wondering if anyone can suggest what might be causing them or if they are normal?

Thanks in advance
