P0456 code 2020 m340i
Has anyone had this code yet? Its a small evap leak. Its been on for 2 tanks of gas so I know its not the gas cap, and its tight. I just don't want to drive almost 2 hours to the dealer unless I have too. I attached the code list. Car has 12k on it. Thanks!

What did this end up being? Just got the code thrown this week. I plan to check the gas cap, clear the code and see if it comes back.

I had the same code thrown recently, what resolution did you guys took ? I have checked the gas cap and the fit looks fine. No service availability at the dealership nearby.

Had this happen on my F30 340i… I was running 20" wheels and the right rear wheel actually slowly rubbed through the fender liner, into the gas line. Doubt this is what happened but figured Id share.
