The location of the VDM control unit is dependent on the country in which the vehicle is sold.

- On right-hand drive vehicles the control unit is fitted inside the passenger compartment near the left A-pillar
There are two different versions of the VDM control unit according to the equipment options fitted on the vehicle.
- The basic version of the VDM control unit is used if the vehicle has only the standard VDC equipment
- The high-speed version of the VDM control unit is used if, as well as the standard VDC system, the vehicle also has ARS Active Roll Stabilization (Dynamic Drive). In that case, the output stages for controlling the ARS valve manifold are also integrated in the VDM control unit.
