The vent valve in a C230 Benz is part of the vehicle's fuel system, specifically designed to manage fuel tank pressure and prevent vapor buildup. It allows excess fuel vapors to escape from the fuel tank when pressure builds up, while also enabling outside air to enter the tank as fuel is consumed. This helps maintain optimal pressure levels, ensuring efficient fuel delivery and reducing emissions. The valve is electronically controlled and operates in conjunction with the vehicle's onboard diagnostic system to monitor its functionality.
