Introduction to the reasons for no response when turning the key to start a Volkswagen Polo: If there is no sound from the starter, one possibility is that the battery is dead. Another possibility is a faulty starter. When the battery is low on power or nearing failure, symptoms such as difficulty starting and flickering dashboard lights during startup may occur. Additionally, the capacity and voltage of a battery nearing the end of its lifespan will decrease, and it may fail after just one or two attempts to start. Below are methods to maintain the battery and extend its lifespan: 1. Turn off all electrical devices in the car before shutting down the engine. 2. Avoid using electrical devices in the car when the engine is not running. 3. After each startup, let the engine idle for at least half an hour to allow the battery to recharge sufficiently. 4. When the vehicle is parked for an extended period or not in use, disconnect the negative terminal of the battery to prevent natural discharge.
