You can also cheat and use a mechanics stethoscope if you have one handy. It'll save you the hassle of having to pull the belts as you can listen while the vehicle is running....but I advise against this method for obvious safety reasons.

I have a Stethoscope, I might try that way. The X5 engine bay is not the easiest to access though and the engine sits lower inside the bay meaning you have to really lean in. I hope I can hear the noise while the car is running. As I said, it only sounds at start up at the moment.
I will check the belt for play as best as I can. I can also try pulling pushing slightly on the pulleys to check for play.
Hope I can find it.
