Vertical dynamics management (VDM): Notes: Overview
The following functions can be installed in the vertical dynamics management control unit (VDM) as optional equipment:
- Vertical Dynamics Management
- active roll stabilization (marketing designation: Dynamic Drive)
This information describes the vertical dynamics management.
The VDM control unit is activated via terminal 15N by the CAS control unit. At the same time, the VDM control unit is supplied with terminal 30.

EDC means: Electronic Damper Control
Vertical dynamics management offers the following advantages:
- greater on-road comfort
- greater vehicle agility
- Improved independent steering performance and response to changing loads
Vertical Dynamics Management (VDM) is an enhancement. VDM is composed of a central control unit and 4 intelligent damper satellites that are firmly connected to the shock absorbers. These 5 control units are networked via FlexRay . A new feature is that separate EDC valves are now installed for jounce and rebound. This means that the control operation no longer has to be clocked so quickly.
