I have a 2009 XB. It now has about 75000 miles on it and I am the only owner.

It is making a very loud noise from what sounds like the engine compartment and I cant figure out what it is.

It is a very loud rattling that is loudest when I'm idling in drive. The noise quiets down when put into park. It seems to be worse when the weather is colder out. Keep in mind I live in AZ so it never is that cold.

I have no fluids leaking. This noise occurs all the time and driving me nuts. Any experience with this or suggestions on where to start?

If you can get someone to help, raise the hood and stand to the side of the car. Have helper start engine and shift between drive and park. Look and listen to see where the noise is coming from. Loose exhaust shield would def rattle.

Just a suggestion but it sounds like to me that your tensioner pulley is bad they will rattle bad at idle but quietin down under load.
