I’ve run into an issue with my 2018 F56 Cooper S that’s left me scratching my head. Since I got it two months ago, I’ve had to add about 2 liters of coolant, and recently I noticed the coolant boiling after a drive. There’s also hissing from the coolant cap, but the engine fan wasn’t running until I turned the ignition back on. When it did start, it seemed to run at a low speed.
Is the fan supposed to have a high-speed mode? And should it keep running after the ignition is off, like my old R56 used to do?
