I hate reading these threads and thinking "Damn! I have this"... There is definitely clicking going on at idle. I hear it everytime I get out of my car to check the mail. By the time I get to my mailbox after work I've been in traffic for 20 minutes so the car is definitely warm. It'd be awesome if we could get a recording of this noise... Mine is coming from the drivers side. Other than being an annoyance I hadn't thought anything of this..... <sigh>
