HUD not working
If you went to a dealer, their official procedure for removing the HUD requires removing the dash, big time and money!
For DIY, what you would basically be doing is what dozens of members here have done to INSTALL a HUD in a non-HUD car, but not quite as much because you already have everything. So you would just get in, unplug the original, remove and replace with new. The problem comes from one possible hurdle from one mounting stud. For the installs, one of the HUD projector housing mounting tabs is notched so it can be slipped or rotated onto the mounting stud. Since your original doesn't have that notch, I don't know how difficult it would be to remove it. I'm pretty sure others have done it so you might want to start a new thread in C6 General asking about that specific issue.
Anyway, here are some reference threads to look at. Good luck.

HUD install kits but you would only need the HUD itself so less money:
