If the nut becomes loose, the excess movement will eventually strip away the threads and the damper will separate from the bottom mount. Other than the nut coming loose he could not see why the damper would fail in this fashion. Lesson: make sure to check the bottom nut after any adjustment in ride height.

In the photo the two dampers on the right are the front (the ones that filed on my car) the silver plate under the red spring is where the damper rod screws in. This is where the rod threads that screw into the plate stripped away and separated both times. When you adjust the height at the top of the spring the whole unit can turn and unscrew the rod from the plate at the bottom. I am not a mechanic, but based on my discussion with the Audi mechanic and the discussion with Jason, this is what we believe probably happened.
