EVAP Codes intermitten
I have had this code on and off for the last few years and had a bunch of things replaced from fuel lines to charcoal canisters.
A mechanic fixed the issue last year however when i put the car into sport mode and accelerated hard I got the check engine and the p0456. This is the same thing that has triggered this before.
Any idea what it could be and the steps to diagnose and fix?
I have MBsoft 2 and an xtool A80
