Re:
Hi Matt,
Go under the car or put in on ramps and see if the exhaust pipe heat shield is touching the tubing or vibrating against it when the car is running, if it is bent then just let it cool down and bent it back out again away from the exhaust tube.

Re:
OK,
Had a look at exhaust vibrating and it isn't that.
Will have to send it in to a mechanic for the belt tensioner bearing check.
It's weird, I've done some more exploring of the problem. I can't for the life of me find the exact spot and I'm now doubting if it's the compressor, although it's still heavily linked in to the air con being on. It seems putting your foot on the brake also makes some noise.
In order of frequency and volume of the noise.
In Park Air Con on or off - no issues
In Park with Brake Pedal pressed, Air Con off - Occasional few seconds of noise, randomly. Generally OK
In Park with Brake Pedal pressed, Air Con on - Noise starts of sporadic but then becomes consistent.
In Drive or Reverse, Brake Pedal pressed, Air Con off - Noise but slightly softer. Usually consistent.
In Drive or Reverse, Brake Pedal pressed, Air Con On - Loud consistent noise
A family member has suggested maybe the water pump, as it's linked to the air con. My trouble with all these suggestions is that it doesn't happen all the time. At higher speeds it's fine. It's only when crawling or stopped that the noise starts.
What bearing would only make a noise at stationary and not all the time when in use? Maybe it is and I just can't hear it. Who knows.

Re: 2005 T30 - Strange Noise at low speeds or stationary when in gear. Louder with air con on.
It sounds as though it could be the drive belt tensioner, your description is similar to mine when it went a few years ago. Open bonnet with engine running and look for the tensioner, if it can be seen to be moving / vibrating then this would need to checked out by a mechanic. Depending if the belt has been changed previously it maybe worth while to do this at the same time.

Re: 2005 T30 - Strange Noise at low speeds or stationary when in gear. Louder with air con on.
It does sound like the tensioner, the engine vibrates differently in the gear selection. Dunno if youve fixed this yet but try suggesting to the fitter to check the securing bolts of the Air con pump. Slide the belt off and check the pump wheel for notchyness or linear movement.
By the way,if it is the Belt tensioner im pretty sure the VP commondore runs exactly the same bearing(27$) and is hell of alot cheap than our mates at Nissan,
