How is this even a debate. If you pop the hood you can clearly see if the dampers are electronically controlled

[casualDIYer]

If you have adaptive M suspension you have EDC. My understanding is that DHP is adjust on the fly while adaptive M is set it and forget it much like the Bilstein B16, yes, the same B16 from over 10 years ago. If adaptive m didn't have EDC then the Dinan shockwave software update and Dinan's description would all be a waste. See www.dinancars.com for a description.

Just to clear this up, my question was related to how (if at all) cars without DHP (or just M Adaptive Suspension) alter the suspension when changing the Driving Mode from Comfort to Sport/+.

Apparently they don't, since it's a static suspension regardless of being stock or M Sport (704). Which makes sense, but contradicted what sales advisors told me when I was test driving. In hindsight I should have asked them how that was possible without electronic dampers, but didn't think about it at the time.

I had read about and wanted DHP anyway.

DHP is just the name of an option package that includes adaptive M suspension plus variable sport steering.

Ok hate the resurrect this thread but I just took delivery of my 435GC without DHP and I have options to change chassis settings in iDrive. Guess chassis in this situation just changes the steering stiffness

And throttle mapping.

Is this new for 2015's? I've never heard of this coming standard. Perhaps DHP just slipped into some models by mistake?

When you configure "sport mode", which options show up?

If it looks like this, then you have DHP.

[Aaaaaaaaa]

I do see those options in iDrive. However although I haven't actually looked at my shocks I am 100% certain I do not have DHP. Definitely did not order it, it's not on my spec sheet or VIN checker and I feel no difference in suspension between modes. I'm guessing it just allows changing the throttle mapping and steering heft independently now. BMW should have made a separate button for the adjustable dampers. Like a button with a suspension element on it like Porsche does.

That is my understanding, having driven BMW models with the chassis/drivetrain option in iDrive, but no active suspension.

Drivetrain changes the gearbox and throttle mapping in my experience.

Others are stating it is linking the throttle to the chassis setting, is this a new combination for 4-series models and later 3-series productions? It was not the original combination, or listed as such in BMW data.

For the 3 and 5-series (and other ranges) BMW definitely have Drivetrain changing the shift program and throttle mapping; Chassis, the steering and damping (if fitted).

You can have the split configurable menu on BMW models without adaptive damping. We have it here in the UK, depends on the build options, options like SAT.

"Ok, now flip it to sport. Do you feel the suspension change?"
"................................................. No?"
"Hmmm, then we need to drive over some bumps."
(time passes)
"Did you feel that?"
"................................................. No?"
"Ok, moving on, this is the stereo..."

I love it, I go through Sport and Comfort phases. But when I first got the car and tried to show this dual nature off to my wife, while on some rough roads I switch to sport and said:
"Do you feel the suspension change?"
".......................................No?"
"Ok, moving on"

Really Funny!

[KneeDragr]

When I test drove a non-DHP car and put it in sport mode I could have sworn the whole car stiffened up. But looking back, Im pretty sure it just the transmission dropping a gear and giving me engine braking.

If you can have DHP or not have DHP, and still have the ability to configure the chassis settings, then by all means BMW has just managed to make DHP even MORE confusing as an option.

I seriously hate the way BMW fragments options from year to year, and then makes it more complicated through terrible iDrive implementation. It's unnecessarily confusing.

I couldnt agree more... The lack of explanation of options on their build page. And god... I rather google than ask the sale advisor lol.

[Sharp_Cai]

No DHP for me. Ok with driving static suspension.

Not because you sound confident makes you right.

You are correct. It takes body roll away and improves handling. Steering gets tight.

Steering gets tight, yes, but any change in suspension feel is in your head!

Please refer to the BMW University Technical Training Manual for the F30 Chassis, which can be found here: http://prodcds.bmwuniversity.com/lib...20Dynamics.pdf

Section 3.3 clearly states that conventional shock absorbers are standard. (No EDC!)

Option code 704 (M Sports Suspension) provides tighter spring/damper (and a 10mm lower ride height for RWD). (No EDC!)

Option code 2VF (Adaptive M Sports Suspension) is the electronically controlled damper system (and a 10mm lower ride height for RWD). This option is part of the Dynamic Handling Package, aka "DHP".

Section 6 talks about the Driving Experience button, the rocker from Eco Pro to Comfort to Sport (and Sport+ if you have one of the requisite options listed).
All cars have it.
All cars will have a menu in iDrive to configure "Chassis" settings for each mode. If you have 2VF (which, again, comes with DHP) then your Chassis setting applies to the dampers. If you do NOT have 2VF, then your Chassis setting applies to only the steering and DSC (traction control).

Option code 2VL, Variable Sport Steering (aka "VSS"), is the other part of DHP. The difference with VSS is that the rack is faster as you steer away from center. With or without VSS, Sport mode increases steering weight.

I had to put my 2 cents in, maybe this will add some clarity and at least people can take a look at the technical literature.

Want to know exactly which option codes were installed on your car? Get the last 7 of your VIN and go here: http://www.bmwarchive.org/vin/bmw-vin-decoder.html

Wow best explanation of this so far. Too bad average customer will never see this technical manual. Even my CA though I had gotten DHP by mistake.

NO U ARE WRONG!!!
Have you driven both? DHP vs non DHP?? There's a noticeable difference when you: 1) hit a bump. 2) tight turns.
