There is a 5N0201412D air valve in the diesel Tiguang, which is marked as noise in some circuits. If the valve is scored and the air does not pass, problems start with fueling the vehicle. The filling pistol may be shut down in the past or, on the contrary, too late, when the fuel is already derived from the tank's neck.
To resolve this issue, you must contact the service. The wizards will remove the fuel tank and check the ventilation system for obstruction, and if necessary, replace the parts. One of the causes of such debris is the remnant of insects and spiders.
