ESC and AVH and Suspension control failure with new 812GTS

Battery is the likely culprit for that sequence of errors. Been through that with 458 and F12, same issue. It is intermittent as the battery starts to fail.

 

No. Do yourself a favor and have it replaced. Five months without a tender and that OEM battery has to go even if they say it tests OK. You should have enough clout to get it replaced under warranty seeing as you bought new and there was a big delay in getting it. Be nice and reasonable with them.

 

We can never be sure it's just the battery. But indeed, that's probably the cause of 80% of these kind of issues. So it makes sense to swap the battery first before starting swapping ECUs, harnesses or sensors.

 

I know the dealer does not use a tender when I get the annual. Its usually a 2 to 4 day drop off or more depending on weather. The battery is definitely not charged as when I left it. If you are sure the GTS was left for 5 months on an crappy OEM battery and you have software errors then no reason not to ditch that battery. The only question I would have is the possibility there are multiple failures - battery and electronics. Do a search here on battery issues and throwing codes so you get a better idea. Its a very popular topic.

 

My gut says its a battery that has lost voltage. I do not trust the dealer that it was on a tender the whole five months.

 

The battery is indeed the culprit in many instances, it’s amazing how sensitive these cars are if the battery is not 100% perfect. But the good news is that a lot of errors can simply be fixed by charging the battery or replacing it. Like other members said, charge it first and if it does not work, replace the battery (under warranty if possible due to your unusual situation just after a few weeks of ownership following months at the dealership).

 

You are correct when battery reaches a certain voltage below what is needed lights will pop up ! My GTS did this last week after eating somewhere! Several failures popped up. Mine has been on a tender since November when I got it.. car sat for a while a factory before shipping… my Ruf ctr3 did the same after 3 yrs but only when using shift paddles !

 

Ferrari OEM batteries I had in the past were beyond bad. Since then I’ve been asking my dealer to change the battery before I even pick up a new car. Had pretty good experience with Odyssey.

 

I had this come up on my 812SF last year as well, they finally changed the battery for me. Finally being that they charged it up first which I insisted they do not. Once the battery change happened, no more messages. DO not be concerned. I also had this happen on my 458 Italia that the E diff recovery showed, after the battery swap all was well.

 

I had all the same warnings on my SF and it was the battery (including ediff). GTS has been on a charger religiously and no issues. My money in on the battery.

 

My GTS threw 5 error codes on multiple occasions with less than 400 miles. Was at the dealer multiple times. The dealer reset the code monitor and I put it in heated garage and charged it for over a week. I did not get the battery changed but I’m now at 1300 miles since Jan and no issues. My $0.02 is hang in there and don’t worry. Dealer will take care of you with a new GTS. Try the battery change and if not, give it a good solid charge and make sure the charger connection surface is fully clean.

Since the nearest dealer to me is 300 plus miles, I would not be happy with having to ship the car back and forth for an intermittent problem or other issues with the electronics.
