PTU kaput and now cats overheating?

My PTU just decided to give up after 200 miles of ownership. Miles=21794. Car is headed to Hollywood Mechanic today.

I also got this symbol on the dash for overheated catalytic converter. Any help is appreciated:

FYI car has sport cats.

 

Sorry to hear about the PTU failure - and so soon into your ownership. I’ll add you to the database of PTU failures. In which year was your car built/registered?

Overheating cats is a catch-all for a raft of ECU failures which aren’t even related to the cats.

For example, my fuel pump failure manifested itself as ‘overheating cats’.

 

Sorry to hear and hope it gets fixed in a timely fashion. From experience it will be as good as new. Every icon in the book may light up when the PTU fails so I wouldn’t worry about the cats….

Did you try turning off the battery and turning back on? If the ptu is going i wldnt worry about anything else until thats sorted.

 

AN0pax, did you catch my input to the FF PTU failure saga at post #789 in "FF PTU Design Flaw (01/14/2024)? I can send more info if desired. Two PTU failures on a 2016 FF, second in less than one year/475 miles from the first.

 

Thats nuts

 

as others have said, the car will throw all sorts of codes when the PTU goes, don't worry about it till he gets it fixed. My car is with him now as well for a DCT rebuild and other stuff...

 

Thanks Don, yes I did. It’s logged.

 

Get a re-engineered PTU from those guys in England. They fixed it. Will ship you a unit ready to go and credit you when they get your unit.

 

I repeat myself , but it is appalling that Ferrari doesn’t own this PTU/ Sensor issues, They have contributed to the
terrible reputation of a great car.
They are not renowned for their expertise in plastics (sticky buttons) but they are for mechanical innovation.
Truly terrible.

 

Really is - the purosangue has the same ptu right?

 

I just dropped the car off at Black Horse who is removing the PTU and then he’s schlepping it over to Hollywood who will install the improved hardware - a greatest hits of socal Ferrari mechanics. I accounted for this in my budget but it still sucks since I have a feeling the dealer who sold it to me knew what was up and merely topped off the ATF to get the car sold.

 

does anyone know the difference between what Hollywood is doing and what Parks’s is doing to the PTU?

 

I asked the sales guys and techs at both Ferrari San Francisco and Ferrari Central Jersey and they all said the PTU remains unchanged since its introduction.

 

2016 FF. I’m not with the car so I’ll look at door jam tag for more precise dates this Friday.

 

I had the same response from salespeople and senior tech at Ferrari FtLauderdale

 

Great question i unfortunately dont know the answer to.

If you follow the stock (RACE) investors don’t seem to care. Maybe the Puro will put up large enough numbers that warranty costs will have a financial impact.

dyaammmnn, Parkes manufactures an entirely new fork! 8k sterling includes labor so I wonder what the core exchange looks like. Seems like a pretty good deal even with freight.

For me, the die is cast and HM is doing the job but maybe when the PTU grenades on the Purosangue I don’t own, I’ll go the Parkes route.

 

Scout123, my 2016 FF came with a two-year Ferrari powertrain warranty that covered the PTU (and DCT) that was baked into the selling price. When the PTU failed one day after I took delivery, I called my local Ferrari dealer and let them handle everything under the warranty. My total cost to have a new PTU installed was $0.00 including the flatbed trips with the FF to and from the dealership.

The warranty is good into October 2026. I don't see any limits in the fine print on how many PTUs it will cover so figure it will be good for as many as are needed, although I hope that will be none after this replacement.

What I don't understand is why Ferrari when through all the effort for this unique (ahem) 4WD system but then limited it to operating just part time in the FF and GTC4Lusso (V12) and ditched it entirely in the GTC4Lusso T (V8). Someone must have figured out that it had problems.

 

Glad you had the warranty. I spent a lot of time researching this issue before I bought my 2014 FF without any warranty. I think everyone is in agreement that Ferrari crapped the bed on the early PTU design. They had to pay through the nose to cover all those early warranty replacements. Back then, they just swapped out an entire new unit. But again, early on, the ones they put back in still had that same potentially fatal design flaw. I find it hard to believe that in later model years they did not fix this issue internally on the assembly line to avoid even more warranty costs. That is why I opted for a later year model. That said, obviously there have been later year model failures as well. There are a couple of companies out there that broke this thing down, found the parts that were failing, and re-engineered them so they would not fail. They both give warranties on their repair. From my research on this forum, the best one is in England. They have rebuild units on the shelf and ship it right to you. When you ship them your broken unit, they will credit your purchase. They take your broken unit, fix it, and put it in stock for sale.

One would hope that Ferrari also re-engineered the PTU as well. I know someone on here is charting PTU failures. There have been a handful of Lusso failures mentioned. Of course, of this model type (FF/Lusso), in volume, probably 70% of total sales were 2012 FFs.

 

PTU is FF, Lusso, is so far only model issue, The Sensor fault covers all Ferrari models and they have not
taken responsibility, PTU/ Sensor are both huge issues that a company renowned for technical innovation
for have failed terribly.
If this was a brakes issue there would be public outcry.

 

Getting the car back today. PTU really needed the rebuild but now it’s done and hopefully forever. It’s hard to believe that the selling dealer (Luxury Auto Collection in Scottsdale) didn’t notice all of the ATF fluid that was being consumed. Being a 2016 the car is just coming off the Ferrari warranty so it just missed getting a new but flawed PTU put back in it.

I had already budgeted the PTU rebuild so I think this worked out just fine. I’m having Hollywood take a fluid sample from the DCT to check the state of the transmission.
