Evap small leak code P0456
 

I have an 02 audi a6 quattro
check engine is on with the code P0456
evap small leak
ive looked it up and they said it could be the gas cap. I did replaced it but still have the code
any thoughts?
Thank you

I have the same problem right now on my Audi. But my problem is the gas cap. I’ve replaced it, and before the check engine light code comes on, it will flash close gas cap! I just deal with it, or take it to Audi dealership if you have the funds.
