Over the 4 years I've own this vehicle (I'm the original owner) my HUD as well on very rare occasions has not come on. Turning the car off and back on has always worked from what I remember.
I had my vehicle in for brake work recently at a local (non-dealer) shop and also had them run a full diagnostic report as my 4 year warranty's almost done. It did come back that the following error has been logged:
1. KOMBI (Instrument Cluster)
1.1 B7F6E6 Head-Up Display (HUD): fault in the stepper motor
(Intermittent)
Spoke with the tech a bit and he mentioned it was a common problem. When the car starts up the stepper motor moves the HUD through full motion (top to bottom through 255 steps) to ensure it's able to move correctly and set the range of motion - a calibration if you will. If it's not able to do this for any reason it won't start the HUD and an error is logged.
Have a service booked with the dealer now to take a look. EDIT: Dealer will be replacing the entire HUD assembly under warranty. It's supposedly a $3600 CAD (~$2700 USD) part.

No updates so far - was supposed to have the dealer replace the HUD a few days ago but the service rep had mis-judged the work involved and entered 1-2 hours when in fact it's an all day affair (odd as I had even told him ahead of time that I believe the dash has to come off), and they didn't have any loaners available so I had to rebook for next week. I suppose I shouldn't have been surprised given that the service rep didn't know what a HUD even was (he had entered that the "control display" screen wasn't always working and I had to correct him).
I'm a bit concerned with having the dealership spend all day digging under the dash to replace the HUD, but have to assume the people doing the actual work are more knowledgeable about the vehicles than the service rep.
