We have a recent issue with the infotainment issue in the Touareg. Everything works except for the media button. When the media button is pressed it hangs on the loading screen. When the car is started the CD player module in the glove box makes a clicking noise for a few seconds and then stops. I've done quite a bit of web searching but haven't come up with anything. I'm wondering if this could be as simple as a loose connection somewhere, but I can't even figure out how to get access to the disk drive mechanism.

If anyone has come across this before or has advice on troubleshooting, please let me know. Here is the data from the VCDS scan.
