What causes the Golf to make a sputtering sound but fail to start?

[SanSamantha]

When the Golf makes a sputtering sound but fails to start, it is usually due to insufficient battery charge, and the battery needs to be recharged promptly. Below is additional information: 1. Battery: The car battery is an essential component of the vehicle and can be categorized into traditional batteries and maintenance-free batteries. During charging, water decomposition and evaporation are minimal in these batteries. Additionally, due to their sealed structure, they release very little sulfuric acid gas. 2. Working Principle of Car Batteries: A car battery is a device that converts chemical energy into electrical energy. It provides a strong current to the car engine during startup and assists the generator in powering electrical devices when the generator is running. It also protects the vehicle's electrical components.
