Auto hill hold?

My old 04 Z4 didn't do this, my 07 MC does: If I stop facing up hill and stop using the foot brake. The car will not roll back and is held on the brake (without handbrake operated and foot off the brake pedal) for a second or so. It then releases the brakes and will roll back. I presume this is to assist idiots with hill starts?

Is this really happening or have I got some sticking callipers?
 
It's part of DSC+, which is on all new Zed's. If the clutch is depressed, and the car in gear, when the driver releases the brakes on an incline, the car will congtinue to apply the brakes for 3 seconds, or until the clutch is engaged and the car moves forward, to assist hill starts. :)
 
lol Panic sets in the first time it happens you think what the F@@k!

Its a lovely feature now, Ideal for heavy traffic.

........and in addition to, when some secret sensor determines you are driving in the rain, the computer applies the brakes lightly every so often while you are driving to dry the brakes so you can stop without the wet brake syndrome.
 
I knew about the Hill Assist feature before I received the car. I'm still on the fence with it... I love how it will hold your Zed so that you can't get into trouble, but the electro-nanny sort of dilutes the true nature of a manual car. I was really good at driving hills with a manual car before, so I probably will suck now if I ever have to go back to a fully manual car for a day.
 
I haven't made this work yet. I think it only works on steep hills -- I've had the car rolling backwards on shallow inclines. On steep hills I follow my normal procedure and of course it never cuts in.

I know what you mean! I borrowed someone's car on Monday while mine was at the dealer, I got used to the auto 'box and hill hold - been driving for 15 years, on Monday it looked like it had been only 15 mins :oops:

I think I need to buy a manual "beater" to keep my hand in.

to be honest I wish it didnt have it, I never use the handbrake whilst waiting at traffic lights etc unless the hill is really steep and never had a problem with a car rolling back.

I find the brakes bind when you pull away, probably my driving style, but they just dont release it time, that and the CDV which I still havent swapped yet can make it a tad jerky.
 
I used to take great pride in being able to "hold" a car on a hill with my incredible clutch skills - up until I had to keep replacing clutch plates because I was basically grinding the surface away by using it instead of my brakes. I don't mind having the feature at all and since it doesn't exist on my wife's X3 I still get practice all the time at driving without it.

That's not to say that I don't occasionally forget and let off the brakes too soon on a hill with the X3 however :)
 
Have the CDV modified already just got to find time to get somebody to fit it.

found and BMW specialist who wil do it for £40 and say he can program the car/key memory features I want at the same time for pennies.
