is your AC on in the vid? Sounds like it could be the compressor turning on and off (edit after listening again it only sounds like the compressor the last few times it did it)... Climb under the car and check the exhaust system for shinny spots that would indicate metal on metal contact. You could also baby powder the DI seal area (on cold engine) and see if it puffs... saw one of the original seal failure guys do that test in one of his vids, made it very clear where the issue was.

Almost seems to coincide with quick throttle plate opening as the engine is dropping revs.. you get the prominent intake sucking noise immediately followed by the clicking, have you taken a close look at the throttle body area?

Can you make another vid with the hood up? Does it only do it when rollling?
