Help with serpentine layout please

Forgive me if this is routine information, but I searched and wasn't able to find a reference image to indicate the serpentine route with label of each part.

I understand the two indicated items in the red outlined boxes, but would it be possible for some help on each of the other items. On my S65 with 36,000 miles it seems the passenger side top wheel makes a slight noise(seen as top left in image).

I pulled this image from another thread. I don't think I need one of those, but it is possible.

If it's the "grooved" pulley top left and it's squeaking/squealing, it's your idler pulley that needs replacement.

I pulled the outer bearing seals, cleaned with break cleaner until they spun like butter, repacked with bearing grease, put seals back and reinstalled the rest.

The whining noise is now completely gone.

CL600 Bi Turbo 2003 Renntech, BMW E39 530D SE
Hi is there an image for the cl600 bi turbo 2003? Mine has a slight whine too, there seems to be room for me to get to the tensioners but can't find how to remove the belt and how to undo the tensioners so they can be replaced? Many thanks Alex
Ps any tips for an oil change I'm aware she needs Mobil 1 0/40, says approx. 9.5l in owners manual?

Have a look in the owners manual!

They're available from MB on line.
