Amysxfire, congrats on making your own tool! Why are you having to use it?

For future reference, Mercedes sells a tool for the W208 CLK-Class that should work very well for the Crossfire: p/n 2088990080. Dealer price ~$20. It looks much like the Crossfire tool with the angled, thin 10-mm wrench at one end, BUT it also has the needed 6-mm hex wrench aka Allen wrench at the other end. Thus, this tool can be used conveniently for both tonneau cover lock and rear bow lock.

Instead of a 6-mm Allen wrench, a T40 star wrench will work on the rear bow lock, as well. Turn clockwise to unlock manually.
