Just thought i would ask incase someone has an idea before i take it into a garage.
Sometimes when sitting idle you can hear this very low whistle noise which seems to pulsate if you know what i mean, it seems to be coming from below the inside of the car ( under where the front seats are ) it does not seem to be coming from the engine? if i just touch the accelerator then the whistle stops, its only at idle i hear it, could this be a very small hole in the exhaust??
Sorry if this is a strange one! lol , is it even something i should get checked? just ignore it?

A long shot, so please ignore this unless you have an OEM sat nav in the car ...
... but if you have the mini sat nav, you could easily be describing the noise that the cd/dvd drive makes when loading up map data. The disk drive is located right under the driver's seat, so it's just possible that's what you are hearing - you'd not hear it while driving, only when stationary. Even gently raising the revs at rest would probably mask the sound enough for you to think it had dissapeared. It gives a whistle-like sound as the drive spins up the disk and reads it. It may "pulse" too, i.e. the whistle will rise & fall in intensity several times in close succession (particularly if the system is not working properly i.e. a duff drive/disk that causes it to permanently "seek").
Like I say, a long shot, but just in case it saves a trip to the dealer ...

I don't have the sat nav but I appreciate you trying to help out :-)

99% its a hole in you exhaust on the joint from the manifold
because when on idle there is no pressure pushing the gases out so them leak and make a screaming/whistle noise when you rev the car the gases are forced out so they dont leak as much if at all hence not hearing the noise

Thanks for the reply, i had a feeling this may be the case, if this is the case and is coming from the front end, is this expensive to sort out? doesn't require a full exhaust does it :puzzled:

A bad waterpump bearing will also make such a noise. It will also disappear if you blip the throttle.
If you stand in front of the car looking into the engine bay, the waterpump is on your left hand side, however, down by the serpentine belt.
