I had the same problem on a C7 last fall but the fix was much simpler once I
discovered the problem. The guide pin in the dowel that passes through the
keybed and lifts the damper tray, was loose in the dowel, had ridden up in
the hole and was clicking on the aluminum damper tray, the underside of
the top of it. I removed the dowel, then the pin, put in a drop of thick CA
and inserted it all the way down in the hole, re-installed it and no more
click!
