Regarding HDC, I've used it several times on my sister's steep hill (X3 and now X5). No sweat to descend a steep snow covered hill. They also show it off at the BMW PC if you do PC delivery, etc.

Well the pathways were that weird wet/slick mud in some areas. I'm not talking about mud bogging, just that half-wet/half-dry mud that is only slick on the surface. When I encountered that stuff, it seemed as though the truck would become confused and do what it's programmed to do, which is good. However, on that type of surface, it becomes more of a nuisance than a help. Sure, the truck slid a little bit but after the half-inch of surface mud, it would dig down to the dirt and get going again instead of losing power at that wheel.
It's just a lot smoother of a ride when the truck is "allowed" to slip a bit instead of limiting power to wheels because of a little slippage.
You know what I mean? I guess it's hard to describe.
