View of vehicle from right rear
Location
The drive unit control unit is installed on the right in the trunk.
Task
The drive unit control unit coordinates the transmission modes.
The following transmission modes can be selected:
- "C" (Comfort)
- "S" (Sport)
- "S+" (Sport+)
- "I*" (Individual)
Representation in Audio/COMAND display (A40/8)
The transmission modes, as well as the representation of the all-wheel visualization, are shown in the Audio/COMAND display.
Coding
The drive unit control unit can be coded and programmed, i. e., the complete control unit software can be updated.
CAN network
The drive unit control unit is a participant of the following CAN network and exchanges data with other control units:
- Drive train CAN (CAN C1)
- User interface CAN (CAN HMI)
Suspension FlexRay (Flex E)
The drive unit control unit is a participant of the suspension FlexRay and exchanges data with other control units.
