I can help you a little bit. I have a 1999 S500 Grand Edition and I have had issues with my trunk. From my research it seems that there are 2 pump systems. One for the Doors and Trunk Handle and One for actually pulling the trunk down.
My trunk closes and the handle pulls in but the trunk does not close all the way. When I go over bumps or pull up lightly the trunk will release a few inches and the handle comes out. When the handle is out that means the red light will be on in your dashboard.
There are so many possible combinations going wrong and most likely your pump is failed totally if you cannot get it to close at all. Try pulling Fuse 9 and Fuse 3 to reset the pump. If this does not reboot your pump it is probably dead
If its not dead then there is either a leak in the lines of the pump or the pump pressure is too low or too high, which can be adjusted (I believe instructions are on this forum somewhere).
Hope this helps..If anyone can help my get my trunk from partially popping please help me!!!!!
