This is the accessory belt. A/C, Power Steering, Alternator.
The N52 engine has a timing chain that handles the valve timing. Other (Japanese) cars I've owned in the past have a timing belt, which I think is what you are referring to.
As I recall, the Bentley manual says to replace the accessory belt on the N52 engine every four years. I don't recall there being any mention of a replacement interval for the tensioner and idler pulley themselves. I could be (am probably) wrong though.
I did mine at 80,000 miles (not km), figuring it should now last until my odometer says 160,000 miles. That's another 7 or 8 years, and I am sure to be replacing a lot more in that time.
