488 Stuck in Wet Mode and Dealer Cant Clear Lights

I had a similar experience on my 458. Since you have ruled out the battery, it could possibly be a brake or speed sensor failure. Shouldn’t be a very expensive fix if that’s what it is.

This has happened to other FChat members so a quick search may provide you with some good information.

 

Happened on my 458, was a cheep brake switch.

 

Cheap is relative...

 

lighting strike?

 

Change battery again……Just sayin

At least swap one and make sure new battery is not a dud.

 

A fuse is there to protect the wire from melting and the car catching fire. Full stop . Thats its duty. It is not there to protect any electronic parts of the car.

Automotive fuses generally are slow burn so they wont burn if slightly over than the fuse rating.

100% for the fuse to burn there was a short. Either you accidentally touched an earth or there was a surge ( capacitors discharging ) or an electronic part after the 40 amp fuse has failed and shorted.

IMO Ferraris are not simple cars like a Toyota. I would only ever let the dealer to change anything electrical.

QUESTION Is the car at the dealer ? If so they are stating that they have to go back to Ferrari ? If so , ild say they will find what caused the 40 amp fuse to burn. Will it be your fault ?

Now if the car is at home, Mate dont panic. Get the car to the dealer and get them to reset the codes.

Like I have said many times before . My battery finally had dead cells, many codes and stayed in wet mode. Drove it to Ferrari , new batter = no issues all cleared.

 

Just a comment : I dont believe your dealer is that good and or they are just too busy and feeding you BS.

I unfortunately bought the 488 GTB electronic workshop manual but it didn't have the electrical Or else I would have told you what happened.

At the end of the day if everything is cleared and working dont worry about what happened.

 

My 2017 488 Spider does the same
Changed the battery still does it
Took to dealer for test and they said it’s low volts and to keep on charge but still does it
Charged for 7 days straight then started it and drove 200 odd miles no problems then stopped for petrol then started it and guess what!
Iv just learned to live with it now and turn the engine off for 20 secs then back on and all clear and good to go!

GF is also stuck in wet mode. Any tips guys?

 

Now that was good.

 

Did you put a new battery ?

 

Brand new at Ferrari dealer

Everyone should have an Antigravity battery. Easily the best $1k you can spend on a Ferrari. If it turns out to be bad battery/low voltage that will solve your problems permanently and the benefit of not needing a battery tender.

 

Hmmm interesting!
Can you back this up with facts?
I just had my battery replaced at Ferrari main dealership and they never mentioned this to me?

Just ask anyone that's installed an AG battery. Plenty of threads and info on the forum. Ferrari doesn't mention it because they want to sell you their own overpriced battery that will fail in 6 months and then you'll need to come back for another one. The battery in my FF died twice even after having it on the tender 100% of the time. Replaced with AG battery, all electrical/battery issues gone. Car cranks right up after 2 weeks of sitting without tender. If the battery ever dies you can restart it with the touch of a button.

 

Have had one in my FF for a year and no problems. Not been on a tender since I installed it. Go off for a week and non problems.

Highly recommended. Tho installation is tricky.

In that case your car has underlining problem.

Get Ferrari to sort it out.

 

My 458 is at Newport Ferrari now with literally the same issues! I have the New Power warranty as well, I'm hoping my resolution is as easy as yours.

 

They haven’t officially diagnosed the car yet, but if it’s not covered by warranty they did say it’s $300 for diagnosis.
