That's just the real trick, isn't it?
As for you, Rossyl, with your love of Star Wars (and capturing pretty well the din from my rear end):

Mine has just started doing this too. I read somewhere it was due to the hot weather and maybe breather pipes, not conclusive though. I have noticed however, that when the howl starts, then I lift off the accelerator it goes. No loss in performance or mpg, mind you mpg couldn't get any worse I don't think
On a serious note, be sure to get it checked as it may be the start of this...

Fingers crossed it is not.
Not sure about whats mentioned in the links above, but in mine it was a failing rear hub bearing assembly......common fault, if it increases with speed and from rear
P
The problem is certainly intermittent with mine... Suspect it may be because when I put my fut down it's drowned out by the howl of the engine / the racket playing on the stereo!
Don't suppose you can recall where you read about the breather pipe issue? Conaero mentioned the same thing, above... Wonder if it's down to the heat making something expand and lose airtightness.

There we go,not definitive but someone else with the same problem. About 3rd question down
Mine definitely started as the weather temperature increased
Funnily enough mine stopped yesterday and had a moment itself, popped it in to neutral and gave it a blast at the lights. Many frowning eyes........if only they knew what we had to put up with
