DDC stands for Dynamic Damper Control. It replaces standard or M-Sport suspension.
The rocker switch (Eco Pro/Comfort/Sport) is Driving Experience Switch. All X1s, regardless of their trim or suspension have this switch. If you have DDC, you will be able to use the stiff suspension setting when in Sport mode (or switch it off if you don't like it). If you don't have DDC... well, it's obvious really...
nothing suspension related will change.
Gear lever in auto or manual position also makes no difference to suspension settings without DDC.
M-Sport suspension is stiffer than standard suspension. Driving Experience Control has nothing to do with this. If you have M-Sport suspension, you will have an equally stiff ride in all three settings of Eco Pro, Comfort and Sport.
What I'm trying to say is that the BMW rep you spoke to was talking rubbish.
Simple explanation of it goes like this:
- Standard suspension is the softest, regardless of Driving Experience setting.
- M-Sport suspension is the stiffest, also regardless of Driving Experience setting.
- If you have Dynamic Damper Control, Eco Pro and Comfort modes are soft. Sport mode can be customised in iDrive to be soft or as stiff as M-Sport.
