I have 04/2006 build with 1700 miles and I have just noticed the tick when the engine is cold. I, too, usually let the car sit and idle for a full minute or so before putting it in gear and haven't noticed it while driving. I think it just started recently, as I never noticed it early on.
I changed my oil filter last weekend around 1600 miles or so (planning on a complete oil change between 2000-2500 miles). While having the hood raised to check for leaks around the oil cap is when I first noticed the ticking.
