Several electrical problems need help

I have always dreamed of owning a Ferrari and I finally was able to purchase. Maybe I’m dumb,
But After stalking Ferrari’s on insurance auctions I finally pulled the trigger in a previously flooded FF. It runs and drives incredibly….but has electrical several issues. Was wondering if anyone could help diagnose. I did put in a new battery.

Working:
Starts well
Runs and drives great
All lights int and ext
Full A/c
Turn signals
Windows
Locks
Cig lighters
Power start
Reverse
Auto
Parking sensors
Mirrors fold in
Rear view mirror auto tints
Backup camera
Gauge cluster

error messages
“System not programmed”
Radio flashes logo then nothing
“Manitino error”
“4wd failure”
“Low 4wd atf oil pressure”
“Airbag system failure”
“Avh system failure”
“Electrical system failure”
“Tpms inactive/ won’t work”
“Adaptive light failure”

Are these all fixable with a new engine ECU? How can I best approach?

Also, but not as important.
Seats don’t all work
Seat belt assists not working
Trunk freezes
Gas cap doesn’t open
Front camera won’t turn on

why? how much cheaper are you paying for it? The cheap Ferrari vey often is actually the most expensive one. I think your list of issues are way deeper than some electrical gremlins that we are used to see with simple battery issues.

Good luck. Keep us updated.

 

Welcome to the forum.

It only takes one bad ECU, wiring loom or connector to throw out a cascade of error codes many of which are seemingly unrelated. For example, my car threw a ‘catalyst temp impossible’ error and it turned out to be a dying fuel pump.

You are going to need good diagnostics tools and the skills of Magnum P.I. to chase all of them down.

Good luck !

 

Well this does look like a bad battery, but if you've already changed it (and are sure it is the right type), then I'd with with either ECU or wire loom issue. It takes just one CAN bus line to be intermittently shorted to ground to throw all the CAN bus off, and you will see all these messages. Next step is diagnostic tool to try and identify which module is wrong.
Any chance your car was flooded?

 

I appreciate the response. Yes. It was flooded. What’s a good diagnostic tool?

 

I'm from Houston where flooded cars are a dime a dozen

You'll never solve the gremlins, do you have the service manual / wiring harness?

I'd much rather buy a salvage wreck than a salvaged flooded car.....

 

As someone mentioned above: New Battery for sure, and then new front gearbox - or PTU as it is called - for some of the errors, but new ECU? Do not think so - it would run terrible if an ECU was cooked....

But just like anyone else here, this is just the start....

 

I’m sorry but why would anyone buy an expensive, modern car (which relies on electronics) which has been flooded?!

Even if cheap, it will undoubtedly have a host of issues. If it were me, I’d try to resell and it buy another one!

failing that, just drive it and enjoy it while you can, hoping the error messages are not actually symptoms of real (mechanical) problems. But I’d say you’re on borrowed time…

 

I would start with the lower most ECUs that are more likely to have been affected by the water. Remove the seats, look at the wiring and look for corroded wires/connectors. I think this is the kind of things that will turn really expensive really quick.

 

To the haters on here- Simple, because I wanted to my guy! It’s got 2,000 original miles fully loaded FF. I’m in it half price (for now) A gamble yes, but I like projects. That said if your only input is sell it or what we’re you thinking - save it! …..All wiring looks really great. No corrosion at all. I was also thinking since it runs so well that most ECUs are fine because the items work. Fuses are all there. I found one area in the lower passenger floor board where some contact are fried, but now sure what it was plugged in to, if anything. I’ll post a pic.

It probably doesn't need a new PTU - either the sensors in it are fried or there has been water ingress into the unit. Either way, that's the most likely source of the three 4wd, mannetino and ATF oil pressure errors. Worst case, a full rebuild (and upgrade while you're at it) will still be cheaper than a new unit.

There are also lots of ECUs on the car which don't necessarily control the engine itself.

 

My understanding is that the independent shops use the Leonardo Diagnostic tool. Best to borrow one or find a used one as I believe that a new one will set you back c.$20k. The last used one on FChat went for $8.5k (and it only had the software module for older cars, not the FF).

 

Yes I agree that the best course of action for the time being is probably to get it to an Indie to get a proper diagnostic, and to start from there. You can also keep looking for the obvious marks of water damage by checking the ECUs one by one.
I would also change all filters and liquids in the car, just for good measure. You dont want water mixed with your oils.
And for one, if you paid the right price for it, then I think it's a great project! I sure hope you document everything you will be doing and post pictures in here.
