Checking the status




- Ignition on
Check if the malfunction is permanent or intermittent by activating the EVAP-valve. Listen for clicking sounds and/or feel the valve for frequent vibrations.
If the valve does not vibrate, this indicates a permanent malfunction. If the valve vibrates, this indicates that the malfunction is intermittent and not active right now.
