Where is the N13 charcoal canister solenoid valve located on a BMW?

[Kimberly]

BMW N13 charcoal canister is normally installed above the right rear or left rear floor panel, and the solenoid valve is generally located near the throttle body, serving as a three-way valve. Introduction to the charcoal canister solenoid valve: The charcoal canister solenoid valve is a device installed in vehicles to reduce air pollution caused by fuel vapor emissions while improving fuel efficiency. When the vehicle starts, the solenoid valve opens, releasing the adsorbed fuel vapor into the intake manifold for combustion in the engine. Working principle of the charcoal canister solenoid valve: Due to the sealed nature of the fuel tank, fuel consumption creates negative pressure inside the tank. Under this negative pressure, gasoline vaporizes more easily than under normal atmospheric pressure. When the engine is off, the charcoal canister stores the mixture of fuel vapor and air emitted from the tank in the micropores of its activated charcoal, preventing the vapor from escaping into the atmosphere.
