DDC is the car detecting an impulse on the front and calibrating the rear suspension to better handle the bump when the rear hits -- dynamically adjusting the dampers. It is not the selection between Normal and Sport (or Sport+).

To add (cause I'm on my iPhone and cannot edit posts), the Drivetrain settings in the rocker switch correspond to a system called Dynamic Drive Control. This system is documented with the 5, 6, 7, and Z4. It is not written down for the X3, but the Drivetrain settings correspond to those in the 5, 6, 7, and Z4.
The chassis settings do not, as the 5, 6, and 7 all have Comfort and Comfort settings, too. |

OK, DDC = Dynamic Drive Control in this context not dynamic damping control or variable damping control (VDC). You do have Dynamic Drive Control otherwise you wouldn't have Normal/Sport/Sport+ modes. You have Dynamic Drive Control because it's always included when you have Variable Sports Steering or VDC (you have VSS). It has to be included with VSS or you'd have no way to easily change the tightness of the steering when driving. The DDC abbreviation doesn't help as it can mean two completely different things: Dynamic Drive Control and Dynamic Damping Control. In the UK though it's usually called Variable Damper Control which makes it easier to to distinguish. Call it Variable Damper Control or Dynamic Damping Control but they are both misleading because including this option gives you both dynamic changes in your suspension which happen automatically, and also a user configurable ability to vary the firmness of the suspension. So perhaps it should be called Dynamic Variable Damping Control

The steering is variable sports steering which is separate unless you're not supposed to have this option either. I don't think you'd get Sport/Sport+ modes at all if you had no damping control and no variable sports steering

So, now, under "Safety and Security" in the "Model Highlights" the BMW USA page provides:
Electronic Damping Control Electronic Damping Control lets you easily switch between the NORMAL, SPORT or SPORT+ gear settings with just the push of a button. Using the data collected by sensors, the Electronic Damping Control calculates the best setting for each individual wheel and continually adjusts its suspension accordingly. This shows integration of the manual and automatic aspects of adjusting the suspension on the X3 (I think; the word "gear" seems a poor choice here). Unfortunately, I can't seem to find anywhere on the page how one gets this on their car. It's not listed in the Standard Features, and it's not shown as an element of a package that I could find.

DHP was a tough decision for me but I decided to take the $1500 and save it for the downpayment I want to put on a CPO 135i in the spring. Little Dinan chippage puts the 135 at 50hp over the 1M... True story

The window sticker reads:
Dynamic Handling Package $1300.00 -Variable sport steering Dynamic Damper Control & Performance Control are part of the M Sport Package & I assume the SAP as well |

SAP or MSPORT packages DO NOT include DDC (VDC) or variable steering... "the switch" is your "performance control" that comes with the SAP/MSport and only adjusts chassis (not suspension) and throttle/shift points. If you want to know for sure if BMW snuck DDC in on your vehicle just look at the front struts and see if there are any sensors/wires coming out of them. Others have posted pictures of what DHP struts look like plus there are diagrams online parts catalogues that show the difference as well. |

Does anyone find it strange that Dynamic Dampening is no longer listed under the DHP description? I emailed my CA asking about it, no response yet.
Dynamic Handling Package • Variable sport steering • Performance Control ? Where did Dynamic Damper Control go?

This is nuts. The only features listed on DHP now are VSS (Variable Sports Steering) and PC (Performance Control). DDC/VDC used to be listed, but isn't anymore, though the price didn't change. If you get M-Sport, PC is included and you get $100 off DHP, which maybe only gets you VSS.
What is VSS anyway? I've read the description, but how is it different from this feature listed as Standard? "Servotronic vehicle-speed-sensitive power steering". So is VSS just "sportier"? Side note: On PC, it sounds like the $100 buys you a software setting, but not the ability to set it (it's just always on). Is that right? So do you really get anything at all for your $1300/1400 bucks? |

My CA returned my email today. He doesn't know why Dynamic Dampening is no longer listed as being in DHP. His regional manager didn't know either and escalated the question to his BMW NA rep.

To the OP. I was in your similar situation. Finally what swayed me into getting it was this: I spent so long reading through posts trying to determine if I wanted it. I kept going back and forth. In the end it's not worth worrying about so much so I just got it so I wont regret it in the future and could stop sweating over it.
