VW Jetta

Have p0442 code. Reoccurring. Ive replaced fuel cap with oem, fuel level sensor(as it stopped working), carbon filter and The EVAP diaphragm on top of the engine.
I do not know what else to do. Hoses look fine

Most common failure part would be the Canister Purge Valve(8).


VW Code P0442 Description

EVAP emission control system small leak detected.
