I’m not playing dumb, I just want to test on different road conditions and would like to ensure I’m using the correct settings if any are required. I have a great stretch of road in mind that in places straight and rough and then turn very quickly into sharp fast bends.

Ok, as said before there is no on/off button like the adaptive button besides the gear shifter on G01 pre LCI and the adaptive suspension is not bound and changeable to the drive modes in general like G01 LCI as drive modes in the old form no longer exist in iDrive 9. It's now only the personal profile with mood lights more or less and a ECO and Sport profile whereas there is no individual ECO or Sport profile like on G01.

Adaptive dampers are always on in ECO and Personal Profile and are regulating based on the Comfort characteristics line which means full regulation of the damper valves from open (soft) to nearly closed (stiff)

Only in the Sports Profile is a suspension setting you can change between Comfort and Sport. This is to limit valve regulation not to fully open. See picture below. In all other profiles damper preadjustment can't be changed.

IMHO UK bmw page is wrong and they have copied the text from G01 description which is misleading. There is no Sports Plus damper setting on the G45 like stated in your picture above.

Also M50 suspension characteristic lines are different to all othe engines as the M50 damper characteristics are more towards firmness even in Comfort mode.

So as a fact you’re stating that Adaptive Suspension on the G45 works only for sport mode ?

I understand what sport mode is, and the X3, and other models, have used complex VPD systems, including step less electromagnetic valve dampers that offer a millisecond level adjustment etc for a while. Some models used these dampers in combination with another system called Adaptive Driving Experience mode, which BMW non longer offers under that name on the X3, and perhaps it’s called something else now, but I can’t find detailed information.

The point is, as a driver I may like the option of Adaptive Driving Experience Mode, to achieve a softer more compliant ride, or harder sportier ride, based on my driving style and road conditions etc. I still have all the goodness of adaptive dampers, but I don’t need to press a switch, touchscreen, or use voice to change mode on the fly, I can just let the car provide the ideal dampers on fast switch bends, and then be compliant and softer when on rough straight roads , without doing a thing.

If the G45 offers this I’d like to give it a try. Hence, ask Raven for the iDrive settings to achieve this.

Hope that makes it crystal clear for you.

Is that a troll question. Just because I said adaptive mode has firmer suspension setting, doesn’t mean it is absent in comfort mode. It has comfort oriented in comfort mode and sport oriented in sport mode. Nothing more to say. Ravenous has explained it very well in last post.

Errrr…. No, it’s because you said -

As I said before adaptive suspension works, not for comfort level, but for sport mode.

So how should I read not for comfort, but for sport ?

I think he got it wrong.

Everything you need to know is in my last answer.

There is no Comfort mode in terms of classic iDrive 7 drive mode but only as a preselection for the characteristics in Sports profile.

Thank you for the explanation.

I’m not trying to play dumb, but in the ECO and Personal Profile, adaptive dampers you say are always on, based on Comfort characteristics, but at what point does the adaptive dampers characteristic dynamically change in these profiles to more sport like and back to comfort without driver intervention ? Is in based on driving style, road condition etc as described below ?

I’m just trying to map Adaptive Driving Experience Mode, which used similar electronic damping technology, but also switches modes dynamically.

I assume for X3’s fitted with dynamic electronic dampers, the dampers are always on.

Yes adaption of the dampers during normal operation is based on road condition, actual speed, steering wheel angel, brakes, map data and so on.

It works realy well. Principle is generally the same in all "MyMode" Profiles but as explaned before in Sports the characteristcs are more firm with the valves inside the dampers initially more closed.

He explains the idea of different characteristics:

Thanks, I understand the difference between firmness levels etc. but it’s the Adaptive Driving Experience Mode that I’m struggling to translate on to the current iDrive 9 X3.

Maybe when I try it for myself on some great roads I have in mind, I’ll have a clearer understanding of how it does or doesn’t work. These roads are currently very harsh on firmer suspension on some of the straight sections due to surface issues, so better with more compliant dampers, but are also frightening/dangerous with softer comfort like suspension if you hit the sharp switch back bends at even moderate speed, hence the system needs to switch to much firmer setting quickly, and then back to being more compliant on the rough straight bits.

I can see how the profiles you mention adapt to the road and driving style changes, and compare.

The mode you’re looking for in the G45 is called Personal mode. Also, it’s not just the Adaptive mode that has become fully automatic in the car. Even the high beams no longer need to be manually activated once — they’ve become fully automatic as well.
