    Recently acquired a 2019 with 11k miles, bought from out state Ferrari dealer where it was originally sold. Flew to test drive and seemed as expected.
    Had it delivered and I don't think I had done 10 miles, parked for lunch and then got check engine after restart to return.
    Got P0442 which indicates small leak in evap control, anyone have any experience or know of common points of failure?

    Reset the code, keep it on a tender, and drive it until it pops back up.

    I’d bet its voltage after the long nap in transport.

    Unfortunately does not seem to be battery related; cleared code, charged overnight and got it to run test again.
    Evap 3C test 81:
    Acceptable range 0-0.150
    Result 0.176
    So it's marginal but failing, I would love to just change the gas cap as a first step but we don't have one...

    Is it in your interest to try half a dozen start and drive cycles to see if it clears? Weird messages on Cali T may occur when battery charging issues arise, these can take a half dozen driving cycles to clear.

    Hopefully it's not as serious as it seems. Sometimes when I start prematurely (not allowing all the electric systems to communicate) several errors would pop up , which is a relief to me because I know it's just a battery error. Goes away after a proper start-up. Seeing one or two isolated codes, I'm not so sure. Do you have warranty on it (power or extended?)

    Well evap is not something I would call serious except that I live in an emissions check county.
    Will take it out this weekend to do the clunker manoeuvre of resetting with a full tank (so evap check can't run) and then trying to get all other monitors to set. And then immediately have it inspected.
    Have extended power but it is my understanding it covers almost nothing.
