Hi guys, Had the front bumper off my 2022 812GTS to fit some carbon lips, back together and started car. I now have literally every failure known to man on the screen - E-diff, power steering, engine control unit, rear wheel steering, F1-Tac,Manettino etc. Car will engage first gear but I have no reverse. Before I call Ferrari embarrassingly, any ideas? I have tried disconnecting battery. Many thanks! Gary
My first thought, but its all good voltage wise. Running we have 13.8-14+v and engine off showing a good strong 12v I double checked I hadnt left anything unplugged, but it was only the parking sensor multi plug.
Clutching at straws, it might be worth locking and leave a few mins. and unlocking, do it a couple of times, that sometimes fixed glitches on older cars.

I'll offer my 812SF experience After driving the brand new car with a 100 or so miles , after a few hours during a road trip I got all sorts of warnings and it went into limp mode , it wouldn't shift properly (I can't clearly remember what else happened). Even after shut down and restart it didn't clear but I was able to get home. Upon repair service manager told me that there is a battery cut off switch , it wasn't fully closed and that was it. I owned the car for a year and never had that problem again. fwiw good luck
No , it was done at the dealer though I got the visual in my head that it was at the battery post. I'm sure someone here knows better than me . You could always pull up a diagram for that part of the car if they're still out there on the web (ricambi?)
A youtuber is facing same issue with his 3 month old 812 GTS which has a novitec exhaust system. Unfortunately ferrari is voided his warranty and suggesting to replace the ECU to fix this issue. More on it here:
