The "clank" may be your dual mass flywheel. The pressure plate bolted to the flywheel has a separate piece that contacts the clutch disk. That piece can turn up to 5 or 15?? degrees. The "clank" is pretty common. When you replace the clutch there is a simple procedure to check the flywheel.

There is a debate about changing to a Light Weight Flywheel (LWFW) and spring centered clutch similar to the older air-cooled cars. Join Renntech.org and or Rennlist and search there. Lots of info for 996 and later.
