How to disassemble the solenoid valve of Volkswagen ea2 1 1 engine carbon canister?

Locate the canister solenoid valve next to the throttle, and then remove the canister solenoid valve with a vice. Unscrew the screw at the top of the canister solenoid valve with needle-nosed pliers, and the canister solenoid valve can be opened (note that there will be a small spring after opening, so don't lose it). Dismantling the valve core will be accompanied by a large number of carbon particles, which are the objects we want to remove. Clean the valve body with alcohol and reinstall it.
