Default CEL/ Evap code, please help.

Couple of days ago my CEL came on, I scanned the car with a generic OBDII tool because I don't have an access to a VAG. I got the following code P0442 Evaporative Emission Control System Leak Detected (small leak). I though it had something to do with my Purge Valve since it was making a lot of clicking noises, so I replaced it and cleared the code. In a few days the code came back, but the car behaves normal. I don't know where to go from here. Does anyone have any idea what could be the problem?
