Could be the battery contactor opening.When I press P to park the car I sometimes hear a distinct "click sound" from the engine followed by the handbrake sound.
is the click normal? why isn't always present?
MG EVs don't have a parking pawl, it doesn't have a transmission, just the electronic handbrake.It will be engaging the parking pawl* then the electronic handbrake.
*A parking pawl is a device fitted to a motor vehicle's automatic transmission that locks up the transmission when the transmission shift lever selector is placed in the Park position.
