    I have spoken to this company before, they seem to know what they're doing and only charge around £3k for a PTU rebuild, but using the same level of quality vs upgraded forks.

    They also don't have the greatest reputation if you care to search their name on Google.

    Hi Daniel,
    Yes you may be able to get Shell spirax S4HDX, that is what we use here. The DCT-F3 is a nightmare to get everywhere I believe.

    Hi I can answer this for you, We Made our forks stronger than the OE ones after seeing damage on the first ones we stripped. We replace the forks because along with every other part we fit they are new, custom made and strengthened, non of our parts are interchangeable with the OE parts.
    Every part of the shift fork assembly is made with longevity in mind. Some people will be happy trying a quick seal change some people want to upgrade, and there are options for everyone now.

    I hope this helps
    Martin

    Add me to your data set. 2014 FF with 39,000 miles. Probably going with option of removing and shipping to Hollywood Mechanic for rebuild. Estimate cost is $6500 for them to do this + shipping. If I ship car there it’s around $10,500 for complete PTU job. Getting rebuilt PTU from SS AUTOTECH after credit for return unit is around $11k including shipping. Feedback here shows both are good choices.

    That said, it’s hard to beat the convenience from SS AUTOTECH swap out program.

    Scout123's post has reminded me that it has been nearly two years since I published the last PTU stats update.

    In that time, another seven cars have been added to the failure list, bringing the total to 45, of which 33 are FFs.

    The failure rate seems to be declining so I can only presume that it isn't the hot issue it once was and owners are no longer posting on FChat looking for advice and a shoulder to cry on but are simply reading about SS Autotech or seeing Hollywood Mechanic's YT videos and getting their cheque books out. Regardless of the underlying reason, here's the familiar chart.

    The average age at the point of failure is 6.15 years and the average mileage is 21,900 miles. Standard deviations are 2.65 years and 12,300 miles.

    The FF fleet is now 12.1 years old and the V12 Lusso fleet is 7.1 years old (weighted averages).

    Ferrari built c.2,850 FFs. According to the annual report, Europe and The Americas account for c.65% of sales so roughly 1855 FFs are registered in these countries.It’s unlikely that owners outside these geographies would find their way to FChat to discuss/log a PTU failure (due to language differences) and not all owners will come here seeking information - particularly if the PTU was fixed under warranty or they found Hollywood Mechanic's video on YT and went straight to him.

    The best case failure rate is if we have a record of all PTU failures (and we know for a fact that we don’t). Of the 45 reported PTU failures, 33 are for FFs. In that case, the best case failure is 1.46% over a weighted fleet age of 12.06 years. That’s a failure rate of 0.096% per annum. If only 15% of the owners with a PTU problem reported it on here then the true failure rate would be 0.64% each year. That’s equivalent to 12 cars a year in Europe+Americas or 18 cars a year worldwide. These numbers were 18 and 27 at the last update so we can see that the reported failure rate has dropped by a third.

    I have also updated the recently published stats for failure rate by production year.

    Related question, until I get my PTU unit swapped out, is it safe to drive the FF in its default "wet" mode? Or, could this cause more harm to the PTU making its repair more of an issue?

    It's definitely not safe. The PTU pump will continue to circulate fluid and make the matter worse.

    I don't think that's true, but I could be wrong. When I spoke to Simon Furlonger who do the PTU rebuild, I'm sure they said it wouldn't cause any lasting damage if it was run in wet mode with the PTU not fully operational.
