Do you have is this pulley?

I am replacing all the pulley and bought them based on realoem diagram including part 17 in this picture but it doesn't look like my car has it.
I also checked other m62 engines but I cannot find this particular one.

If you scroll down that realoem drawing to the parts list, it notes that items 15 through 19 are only on manual transmission vehicles. They must be using a common drawing for other than just the X5.

thanks JCL. I missed that. Since I have this pulley, do you think I can use it to replace the AC adjusting pulley. Most likely not, the diameters are different.
