If the oil's been overfilled the breather pumps oil into the intake and damages the MAF, in extreme circumstances the oil drains into the air filter housing and then run down the rear of the front wing, coming out the side air vent and bottom of the wing liner. Ferrari issued amended oil filling procedures in around 2009 IIRC.

btw be aware the intakes are reversed i.e. offside intake/ MAF feeds the nearside bank and vice versa

Many of the electrical gremlins seem to be spurious errors that don't leave a trace in the error logs, low or bad battery is a prime candidate
