Bump Start?
Can one bump start C8?
** Honest question. In theory, ignition can be turned on by pushing the start button and foot off the brakes. Then if the car goes in D or R, one can pull both paddles for neutral can get the car rolling in a slope. Then releasing the paddles will engage the clutch and turns the engine. OP assumes all clutch and gear functions of the transmission is controlled via electric solenoids Vs hydraulic pumps.
*** Not recommended to test on a car equipped with brake by wire system.

It's not possible to shift the DCT out of park if the engine is not running. Carry jumper cables.

Manually Shifting to Neutral
With the ETRS system, the transmission parking pawl cannot be disengaged unless the engine is running. If there is a loss of vehicle battery power, the DT-52388 manual park release tool can be used to shift the transmission to Neutral and move the vehicle. Due to spring pressure, the tool must be applied to the release lever and held in the release position while moving the vehicle. The manual park release is located on the right side of the transmission and can be accessed through the trunk.
