Lost electrical power on a 2011 Cali

Hi everybody, I got this lost eletrical power in just overnight after I take her out for an hour or so.

Batt is brand new Fiamm agm 100ah. Yet, after jst 1 night the next day I open the door I got this down and up window movement and the dome light on then off.

I had the obd reset of all errors with no effect at all the problem keeps occuring as if thr is a parasitic batt drain and the computer shuts off the power.

I was wondering if anybody had encountered the same saga and found a closure [emoji23].

Thanks guys

None sir it is bone stock. However, I forgot to mention that at around in the beginning of the pandemic since March 2020, I did not have the opportunity to warm up let alone drive the car on a weekly basis due to an immense workload for being an MD.

And by around June when I finally got the chance to fire her up, I got a parking sensor error which I ignore [emoji23]. Is there by any chance it is the culprit of the power loss? There is no obvious parasitic drain on the batt, the voltage is a healthy 12.6V without batt tender. Yet, there is now power going to the computer.

Hi everybody I have had the problem fixed but I havent gotten a time to update this thread.

So to avoid confusion and guessing for those who may have the same problem of lost electrical connection, the solution is to replace the NBC or Body Control Mode which basically controls the electrical and immobilizer system. The NBC replacement can only be done by the authorized Ferrari dealership since it has to connect to the principals mainframe to program it according to the VIN.

The NBC replacement cost is €4k.

When I asked what caused the NBC to fail their answer was ‘just the nature of electronics’[emoji23][emoji109]

That’s all folks. I hope I gave a satisfactory closure to this thread. Attached are the pics of the €4k NBC : Image Unavailable, Please Login
