Rattling under the Hood

I must say that I hear this too... almost sounds like something is lose underhood. But it is less pronounced (still slightly present) with 100 Octane unleaded race gas. Dealer reflashed the ECU to the latest file and it made no difference whatsoever.
My vehicle is a 2010 XF Supercharged (5.0 AJ133 SC) 44K miles. There is no noise whatsoever in a 2011 XFR we drove back to back during the trouble shooting drive. Dealer's conclusion is to keep an eye on it to see if it gets worse and otherwise do nothing. That sounds like BS to me.
