Hi, got an awful noise developed which seems to be worse just after starting. It changes intensity with idling speed. I have put a video on YouTube

You can hear the noise reduce about half way through after the engine has revved.
It appears to be coming from the rear left of car. Pretty sure that it goes away after being driven for a while, definitely seems to be less pronounced after warming up.
Any ideas as to what it can be?
Thanks in advance...
