As a FYI. Ferrari of San Francisco has serviced my 599 and I know they didn't miss anything major.
But after a regular weekend from Sonoma to Sacramento 125 mi on-way we parked for a couple days at our place. Returning that Sunday, the Check Engine Management Systems light went on and stayed on even after a few respected turn-off, wait, then on again.
HATE that.
we were less than a quarter tank and knew I had to fill up on way home anyway, so thought even after resetting the gas cap it might go way: nope.
filled it : nope.
wasn't flashing, and yellow so it SOUNDED NORMAL and handled normal. If this were my first rodeo I would panic. But of course we only picked up this car two days earlier and our first time to truly drive it.
decided that even with Ferrari Emergency roadside assistance [we are still under warranty] that them picking it up and us finding our own way home, my AAA 100 mile flat bed would be better but we decided to 'risk it'. Yup we knew this may in fact not be a huge problem.
also, decided--her surprisingly in tune-- thought this may just be a glitch in a sensor as everything sounded/felt normal.
later, next day, at home it did it again. Have the person whom sold it to me living about a mile away. We both decided that I should drive to local Ferrari and check it out.
BUt GOE [ghost of enzo] I needed to stop at the dollar store for some art junk and after getting in and starting it went away?!?!?!?!
will still decide later to check it out.
Taz always has a non-panic answer that is spot on in these situations. So gladly didn't need to reset the system YET, gut this page will be on quick find if happens again
