That is correct, When you take the valve cover off, you will not be able to see much less reach the whole cam bolts. They are behind the VANOS unit. I replaced mine and it took a few hours. Also requires specific S54 tools.
Here is a shot of the suspect bolts from when I did mine. Notice the missing VANOS and CAM Covers.
