PTU failure log

That sux Peter and sorry to hear.....at least the fix will be during months that typically wouldn't get a lot of miles....congrats on driving it 25K miles!

 

Great post. BTW, when a PTU does fail, how will you know? Can you just limp it to a repair shop will it cause damage to drive it.

 

Hey Team --

Right -- once again, there are multiple threads on PTU failure that take hours to cover here on this board, and I've gleefully spent too many hours researching, following YouTube tutorials, and THEN, four years into my ownership, my PTU failed - yet it's Factory Covered under the Power15 Warranty (read all the threads)

I've found that the short-cut/easiest way to get up-to-speed it to watch Hollywood Mechanic's YouTube Videos.

Next best is to visit the Parke's UK website for a corroboration. Very well written and illustrated. Same as Hollywood (Hugely helpful)

I'm booked for flatbed on Wednesday and I've shared all of this with my Dealer reps already -- told them that this factory-fix will fail again, and when I bring it to them the NEXT time, after the next (imminent) fail, that we are going to replace it with the retrofit (upgraded) parts, as shown perfectly by Hollywood Mechanic and Parke's retrofit kit with stronger materials paired with factory design.

Thanks to all their hard work, let us continue to address these little, gigantic, enormous problems together as the FF family we are.

I'll keep you posted.

Peter, thanks so much for posting your experience and keeping us updated. My 2015 FF has 28K miles and so far so good.

However, I am really interested in the dealer's response when you told him next time you expect them to rebuild the PTU with a thrid party's parts. I've had experiences with dealers, Ferrari and others, where they will not use anything other than genuine manufacturer parts. In 2022, I drove my 612 to the FCA Annual in Mont Tremblant. Well I almost drove there. At the Canadian border an oil line to my gearbox burst. The car went to Ferrari of Montreal and they had the car there for a month trying to locate an oil line. I told them repeatedly just have one fabricated at a local shop. They absolutely refused. I had the car transported back to Mass. to my local independent and 3 days later he had the line made and installed. Of course the funny part was he told me the fabricated line was better quality than the Ferrari one it replaced (sound familiar ).

I can't believe that a Ferrari dealer would even consider using Hollywood Mechanic's parts. Not to mention since no Ferrari dealer has ever rebuilt a PTU, they wouldn't have a clue as to how to do it. If they tell you they will rebuild it with third party parts, I'd get that in writing and notarized!

 

Hi,

I've been a Miller Motorcars (Factory) client for about 14 years, a fairly good sized shareholder since 2017 (that probably won't matter), and have enjoyed time with many of the Dealer Sponsored Events, so I am relying heavily on my Dealership Relationship.

I have been maintaining this FF with them as per factory specifications for the past 4+ years including annual preventative maintenance (again, if you know the PTU Failure Thread history, I'm all over this)

Lastly, when I reached out to my Rep, we are pre-agreed that for me to ask for parts from Parke's or from Hollywood Mechanic, that it's not happening YET

So to address your question, we framed the discussion as hey -- let's let the Factory do its work as warrantied -- and when it breaks again, we'll retrofit the improved versions outside of the shop with our pre-agreed outside guys who are no longer with the Dealership, who know this like Parke's or GTE or Hollywood -- so we're going Factory 100% of the way on this thread for the time being / live updates to come. It's getting trucked to Miller Motorcars on Wednesday morning.

That's the bridge when the Factory takes over for now & I'll keep you posted on this thread only.

Did you confirm that the PTU is actually the problem? It's not unusual to get some weird errors with these cars here and there... I've had various ones come up and the best I've ever had from the dealer is a shrug and a "we can't find anything wrong"... the software in these cars is unreliable at best.

 

There's all different levels of "failure" or "failing".....I drove mine for over a year with a "failing" PTU....Dreaded Wet Mode and all the lights going off just happened more frequently....it was finally diagnosed by the dealer but even that was a process.....

 

That is good to know. I want to take my FF up to Quebec City in December. We did take it back in 2020, but I only had 14K miles on it then. I don't care if the PTU failed and was simply throwing warning lights and stuck in wet mode. i just don't want to be stranded up there with a car that won't drive (been there, done that, with my 612).

 

Ah, good for you. At my dealer I'm on double secret probation!

 

Checked in today with Miller in Greenwich. So far so good / noteworthy that the AWD fault-codes cleared themselves upon loading.... will keep you posted.

I keep staring at that pic and wondering is that truck some kind of accordian? It looks like once the car is loaded a cover extends over the whole car. Am I seeing that right?

 

Hello all. Forgive my ignorance, as I am a rookie.
I have finally realized one of my dreams, and my 2012 FF is on its way to its new home!!!
I am so excited, it is hard to concentrate on anything else for the last week or so!!!

my question is: if you always drive the car in sport mode, does that decrease the amount of time that the PTR is engaged? Even though from what I can gather, these failures are inevitable with time, and not so much correlated with mileage. Is that fair to say?

I see some guys doing burnouts off the line (of which my pockets are not deep enough to do. Lol). but in this case, it looks like the car is in 2WD, at which time the PTU is not engaged, correct??

I appreciate all the useful information and the input of all the members here. I look forward to utilizing the site and adding helpful information where I can.

2012 FF
35k miles
PPI stated everything in great shape. As of now

 

There is no way to reduce risk by changing driving modes. Failure rate is very very low overall. Just put some $ aside over time to take care of it when it pops up. Aftermarket fixes are available for fraction of new (and still prone to failure) PTU from factory.

 

I had a chat with my mechanic about batteries when I picked up my car a few weeks ago and he mentioned that the lead on AGM batteries can sometimes break down and puddle at the bottom of the battery closing the circuit which causes the battery to discharge itself. Shaking the battery or moving it (such as loading onto a flatbed) could cause the sediment to move and bring the battery back to life. Something to check out at least.

 

Hey Team,
No updates overnight / this Weds 30thOct --
One really good question from Fernando -- my pick-up Towing/MillerMotorcars driver in his accordion-truck:
"lets get it loaded before the fault codes kick in again".... once the cooling fans kick-on, and until we get a complete recirculate, then we're only warming up...
So if that circlip is broken at the bottom of the box, then let the Factory figure it out for now. I didn't drive it. I only loaded it onto the truck with zero faults flashing.
Will keep you posted.
This specific FChat PTU Failure thread shall remain specific to this PTU Failure message / the battery is 100% fine / tx
