It is completed by the “solenoid”. It is an electromagnet that goes under a 12 volt electric impulse to push the fork (link part between the “solenoid” and the electric motor of the starter) and thus engage the starter drive pinion on the engine flywheel. Following this action, once in engagement, the starter motor of your Audi A7 is activated and turns the drive pinion on the flywheel to start the engine.
