Where is the carbon canister located in the 2017 Passat?

The carbon canister in the Passat is located inside the front wheel fender on the passenger side, which is equivalent to behind the fender. Extended information about the carbon canister is as follows: 1. Introduction: The carbon canister is generally installed between the gasoline tank and the engine. Since gasoline is a volatile liquid, the fuel tank is often filled with vapor at room temperature. The function of the fuel evaporation emission control system is to introduce the vapor into combustion and prevent it from volatilizing into the atmosphere. The activated carbon canister storage device plays an important role in this process. 2. Principle: After the engine is turned off, gasoline vapor mixes with fresh air in the canister and is stored in the activated carbon canister. When the engine is started, the solenoid valve installed between the activated carbon canister and the intake manifold opens, and the gasoline vapor in the activated carbon canister is drawn into the cylinder by clean air under the vacuum of the intake pipe to participate in combustion. This not only reduces emissions but also lowers fuel consumption.
As someone who frequently works in the garage, I've found that the carbon canister in the 2017 Passat is usually installed under the trunk floor or near the wheel axle. This positioning is designed to be close to the fuel tank, reducing the risk of vapor leaks. During maintenance, I often see it in this location, requiring the car to be lifted or using an inspection pit for a clear view. The carbon canister is that small black box that handles fuel vapors, preventing pollution and odors. If the carbon canister gets clogged, the dashboard may show an engine light or a loose fuel cap warning. I recommend checking it annually, especially after prolonged driving in dusty environments where dust buildup is common. The location is fixed, but don't attempt to remove it yourself—mistakes could damage the piping. It's safer to have a professional shop handle it to avoid causing additional issues with the car.
