Dynamic Damper effect

Hi all. New here. Eyeing a new X3 soon.

Is the Dynamic Damper Control add-on merely automatic handling of the Sport/Comfort/Eco options, or does it add something else to the mix?

Thanks.

I believe that it adds something else to the mix, something very expensive. Damper is Euro-speak for shock absorber.

Yes, it's expensive. But almost everything BMW is expensive. I asked because I've read materials that SEEM to imply that Dynamic Damper only decides, without driver intervention, whether to press the Sport, Comfort or Eco buttons. Maybe it's VERY good at that, but the question remains whether it does anything else but that.

It adjusts the Dynamic Damping of the Damper / Shock Absorbers.

But isn't that what manually pressing the Sport/Comfort/Eco buttons does? Am I missing something obvious?

check my previous post where I asked this question along with a bunch of other questions, and fellow bimmerfesters answered in details

They also shared these links with me that proved to be very informative

When you don't have the adaptive suspension option, these buttons merely control the engine response, transmission and steering, but not the dampers. When you have the adaptive M suspension option, there's an additional "adaptive" button that is added to those modes, that signifies that changing modes will also change the suspension stiffness.

Ahhh, I see, thank you. Do you know if the adaptive suspension has a significant impact on ride comfort on-road but on rougher roadways?

I am yet to drive one with the adaptive suspension as dealers don't usually spec their cars on the lot with it, and you usually have to custom order one to get it - which is exactly what I did. I'm not sure if you're interested in the 30i or the M40i; I felt the base suspension on the 30i was too soft for my likings, so I would strongly consider it if you're getting the 30i. However, the M40's base suspension imho is a lot better. I'm not sure what your budget is, but the difference between the 30i and the M40i in general is night and day, so I would take the M40 for a drive before making any decisions.
