Non return valve

I have searched the TIS service manual as well as the forum.......does anyone know where the vanos system check valves are located on the S65? I have that rattle on startup if my car has sat for a few days between uses. I know where they are on the N54 but not the S65. I'm not driving my car as much lately as I have a new work vehicle so the noise is a new event for Purl and I. No other issues, power loss, CE light or stored codes. Appreciate any help!
