The P0496 error code in your Volkswagen indicates an EVAP (Evaporative Emission Control) system flow during a non-purge condition. This means fuel vapors are flowing through the system when they shouldn't be, typically caused by a stuck-open purge valve or vacuum leak. While not immediately dangerous to drive, this issue can affect fuel economy and emissions compliance.
