Hi, I have a 05 C2, When the car is turned off with key removed, I hear the pcm making a noise (a sound of ejecting a CD). sometimes when I open the door to get inside, I hear same noise from the pcm.. Is that normal, Has anyone else had this issue?

This problem was not uncommon for the Cayenne, we still had the PCM replaced. Maybe he is repairable by a third party.

Is it possible this might be the reason my battery is drained if I don't use the car for couple of days?

Should I remove the fuse to check if thats the problem?

For the best, build the PCM out, there is a fuse on the rear panel as well. Look what happens with the battery problem after a while. Instructions for removing and install. can be found with the "search" button on top of the page.
