Without the starter in your Mini Cooper, the car would just sit there. When you turn on the key, it sends an electrical impulse to the solenoid, which activates the starter. The starter then engages the flywheel to start the car. If you hear a rapid clicking sound when you turn the key, or it simply does nothing, you likely need to change the starter. Experienced home mechanics should be able to complete the job in about two hours. You can do it in your driveway or garage.
