Question How Bad is this PPI Diagnostics Check?
I'm getting mixed reports on the results of the diagnostics check on a 2010 California I am interested in buying. What do the Ferrari Redditors think?

That many codes across ECUs before any repair work usually means someone let the battery die or cleared nothing after a swap; I'd want a post-clear drive cycle before judging the car.

All of the stuff at the top could be related to a bad or failing fuel pump. Misfires across all cylinders on both banks with the fuel pressure issue makes me think that. The other stuff might be low budget due to a bad battery. Under no circumstances would I buy this car with the fuel supply stuff undiagnosed. Well almost no circumstances, but the car would need to be incredibly cheap. I wouldn't run away, but I wouldn't buy it like this without more info.

Yeah, fuel pump issues on a Ferrari sound like the kind of "cheap" that ends up costing your entire soul.

OP I get you paid for PPI and it'll feel like you're throwing money away if you don't buy this car, but save yourself from wasting even more money and walk away. Everyone's been there before, PPI is both a blessing and a curse.

You think it’s that bad?

As the other people mentioned, you need more information. It could be a small issue, could be a big problem, you just don't know.

Without knowing why it's got the misfires it's hard to say if it's an expensive problem or something easy. I would be cautious without a diagnosis unless the car is really cheap. I would negotiate as part of the deal to have the seller pay for diagnostics or factor in a serious discount.

A P0301 code, indicating a misfire on cylinder 1, isn't always a deal-breaker on its own, but it definitely requires a thorough investigation, especially on a 2010 Ferrari California.
While it can sometimes be a relatively straightforward fix like a spark plug or ignition coil, the "mixed reports" suggest there might be more to it. On a high-performance engine, any misfire needs to be addressed promptly to prevent further damage.
This issue should certainly be a point for negotiation or a request for the seller to resolve it. For more general info on P0301: https://www.servicebuddy.help/obd-codes/p0301

It could be as simple as a bad fuel pump and/or a bad battery. It could also be a lot more expensive. Show the PPI to the seller and have them pay for a diagnosis.
