The model year 2012 vs. 2013 thread made me think about another item I don't quite get, maybe somebody can enlighten me... 
What is the difference between these different "hold assist" systems?
In particular, what is the difference between "hill hold assist" and "hold assist"?
I would think that "hold assist" on a flat surface was pretty pointless, while "hold assist" on an ascent could be very useful indeed. (Living in a place with snow and ice 50% of the year, a full stop in the middle of a steep hill can be quite tricky when you want to start again. Looking forward to Quattro in this situation by the way!)
"Hill decent control" I cannot even imagine what does.
Checking my brochures, I see that there are explanations for "hold assist" and "hill hold assist", but they are so similar that I cannot tell what the difference is between these two choices...!
