I know, I know - another PTU thread, but this time it might be slightly different... So, to summarise my 2011 FF has around 50k miles and as far as I know the PTU has never been done. I've owned it for 3 months, and after 2 months the 4WD system failure message started appearing, along with manettino failure, low 4WD ATF oil pressure and the car being stuck in Wet mode. I know about the PTU and had researched extensively before buying but knew I'd probably have to stump up the £9k for a rebuild here in the UK, so assumed it had gone kaput. I took it back to the dealer I bought from for diagnosis, and they had it for a while and said it was leaking externally from the supply hose which they changed and it appeared to be OK. The return pipe had already been changed by the same dealer earlier on in the year prior to me buying it. So both PTU hoses have been replaced, but after leaving it for a few days the garage said there is still a small amount of ATF fluid leaking somewhere near the PTU. My question is are there any known weakpoints for external PTU leaks? The garage mentioned where the PTU connects to the diff but that doesn't seem right. Any suggestions based on the diagram below taken from Eurospares? Image Unavailable, Please Login
Check the reservoir hoses (#10) and the white refill reservoir (#6) for leaks. I have heard of these cracking which can result in a leak?
Thanks dude will pass it on. They're talking about having to drop the transmission so I hope it's something simple. It's with them there now
Ok some seals have been ordered apparently and that should fix the problem, although like our esteemed comrade ttforcefed said, nothing is ever simple with Ferrari. I doubt that this will be the last of it. Also the outside temp sensor is faulty (the one on the door mirror) and reads 50c at all times and is also causing an EML! I swear Italians do these bizarre things on purpose just for a laugh and to mess with people
Yes, it should do as I've read from several sources (and the garage doing the work) that the temp sensor is linked to the TPMS, climate control and ECU.
Just as way of an update, the secondary leak was located, sealed and the PTU is working once more as it should. I'm not sure exactly where the leak was but it was described as where the PTU connected to the engine block. The PTU had to be removed and a seal replaced. All covered under warranty from the garage I purchased from so pretty happy with the outcome, although I'm still pretty sure the actual PTU itself will need a full rebuild at some point as I'm at 50k miles.
Yes, this what doing SSAutotech, but in your case it's only temporary solution, because stock seal ring is weak part there, and also SSAutotech installs modified forks in PTU.
Regarding "warranty" would PTU failures or anything short of that be covered under the power warranty?
I had a burst oil line to the PTU and had it repaired at a Ferrari dealer. I did not have the Power Warranty, but I asked the service manager if it would have been covered. He told me it would not. When my FF came off warranty I asked about the cost of the Power Warranty and was quoted $8700 plus inspection. So I've been self-insuring for 4 years and I'm way ahead of the game.
Interesting. I'm usually against warranties but this may have been one area where I would give in. Ive been doing the same with my 458. One clutch sensor repair for $9k but still out ahead for the years used.
I was going through exactly the same questions a year ago when came the time to extend my warranty. I saw that the Power 15 did not cover seals or leak. So I thought it would not cover the typical PTU failure where the seal between the transmission oil and hydraulic oil is made, and decided not to take it. Havent had any issue since Im out of warranty so it looks like I might have made the right call.
For reference and hopefully helps someone with decision making- this is what the power warranty documentation says (excuse the formatting with copy paste from pdf) COVERAGE The Program covers functional defects of the vehicle with the exceptions set out in Paragraph2 of" Terms and conditions of Ferrari "Extended CoveragePlus* Program and in Paragraph 3, "Exclusions*,below 3.

Because dealers is terrible, that's why. For that price they asking, there are should be work high engineers from Germany
Sorry to hear your issues…but iam amazed there isn’t a way to take out this system and run the car as RWD.
