How exactly does hill descent work? I assume it leaves the car in a very low gear to provide maximum engine braking, but I'm sure engine braking alone isnt' enought to slow the heavy Touareg on a very steep hill. Does it use the brakes too? How does it know how much to use and how does it not overheat the brakes?
Just curious.

Without getting overly complicated, HDA keeps the Touareg under control when descending a steep hill by controlled brake applications...So, it is primarily a function of the Brake system, but other things must be in place as well...ESP must be on(another brake function), the T-Reg must be in 1st Gear; not 2nd or 3rd, for engine management...Something the current Owner's Manual is a bit vague about, and the reason behind the infamous http://www.VWWebSource.com
disclaimer...The Owner's Manual even states that the steeper the grade the lower the gear required...Duhhhhh!!!

I should not be so harsh...

as this is, no doubt, a translation problem that occured over here...
But that is basically it...not exactly rocket science, but a lot of fun...

Yeah from what i know, you put it in low gear and with your foot on either the gas or break. it will decend at a speed of 5 mph.
hillaccend is designed to keep the car in one spot agian with your foot off the gas and break it will just sit there.

It would be nice if this worked in any gear, high or low range, the way the Range Rover is supposed to do.
