I have an 08 535i with a sports package and now regret that I did not get active steering. My ratio on the steering wheels is very big compared to my previous M3 and not responsive at all. I'm not sure if this is the way it supposed to be but it drives me nuts..
I was wondering if there are any adjustments that could be made to change this? I suffer mostly when driving on the canyon with a curvy road.
Anyone been noticing the same problem on their E60s? I'm not sure if replacing suspension will help.

I would think that an M class car would have a more responsive steering wheel compared to a non M car.
Active steering isn't about steering response. Its benefit is for driving situations where alot of tight turning take place (eg - parallel parking).
I guess its a pretty good option, but I've driven though a good share of winding roads here in Europe. IMO the "regular" power steering suits me just fine.

I haven't read anything.
I just ordered a 535i w/o AS because it had better feeling at high speeds. I do think I'm going to give the shorter "turn to lock" at slow speeds.

Active steering is all about steering response and exactly suited to drive through s-turns, parking is an ancillary benefit.

There are safety benefits as well. AS can make corrections in the event of a driver screw-up. Here's a little bit-o-info from BMW:
Active Steering Description
"At the heart of the new Active Steering system is the planetary gear set integrated into the steering column. An electric motor in the joint adjusts the front wheels' steering angle in proportion to the Sedan's current speed.
When driving at lower speeds - such as in city traffic, when parking or on winding mountain roads, Active Steering increases the size of the steering angle. The front wheels respond immediately to small movements of the steering wheel, enabling the driver to manoeuvre through tight spaces without needing to make multiple turns of the steering wheel. Parking is easier and agility enhanced.
At higher speeds, bends are more gradual, demanding a smaller steering angle. Therefore, Active Steering reduces the amount of change in the steering angle for every movement of the steering wheel. This gives the driver the advantage of more precise steering at higher speeds, and ensures great stability and more comfort.
If the vehicle is threatened with instability, such as by oversteering or braking on a changeable surface, DSC identifies the problem and can use Active Steering to help overcome it. For example, in order to reduce unsafe yaw, Active Steering can increase the angle of steering wheels faster than even the most expert driver. Active Steering does not interrupt the direct connection between steering wheel and front wheels, so that even in the unlikely event of a complete failure of the electronic systems, the BMW remains completely controllable at all times.

I drove an '05 545i with Active Steering and was very impressed with the turn-in response. At the time I drove it, I did not know the car had Active Steering so I'm assuming this is why the 545i felt more nimble than the 335i sport I drove immediately after. ARS was also very impressive.
Does anyone know the exact steering ratio for a stock sport pkg car, and also the ratio range for Active Steering? (i.e. 13:1 .... 16:1)
Have there been many problems with the A/S system?

I'm not too sure about non-AS cars, but I believe the ratio variance for Active Steering falls between 10:1 and 20:1
Page 57 has details on the 2004 models... I'll assume that hasn't changed thru 2008. "14.1:1 mechanically variable, mean ratio" on the standard steering, 10:1 to 18:1 on AS....

If my sales rep gave me this much info when I made my order, I probably would have chose this option over the night vision.
