Was bedeutet der Fehlercode?
The fault code shows that the canister purge valve or the EVAP canister shut-off valve is not working as it should, either through a leak or because the valve is clogged. The valves control fuel vapours between the fuel tank and the canister, which is the carbon filter. The fault is checked when the leak diagnostic is carried out and is stored if one of the components is faulty.
