Default Check Engine Code: P0455 2008 Audi A4 B7

I have a 2008 Audi A4 S-Line it has 90,000 miles
I have this occurring code and it says to tighten the gas cap.
After replacing the evap sensor and replacing the gas cap, then reseting the check engine light. The following day the check engine light would reappear.
If anyone could tell me any insights on to this problem that would be amazing.
