Simon,
when we first approached Porsche Cars GB over a year ago, we requested just this. In fact, they would never make an official statement but gave an unofficial figure based on supply of parts of only 8% failure. I requested to see the base data for this to check it covered all part numbers etc, but never got anywhere.
For me personally, it is not so much an issue if the seal fails after five years, needs to be replaced when convenient, and you do the clutch at the same time, then the new seal lasts another five years.
Some owners of low mileage cars have publicly disagreed with me over this, saying a failure at any age is a big deal, and that is their right. But I wont be their champion.
Where I will weigh in, is failure at a young age, say in third or fourth year, and in particular, repeat failures, like for Berney.
When I said the breakdown of the survey data was interesting, I meant, the newer the car, the earlier the failure occurred. I hope this is purely because the data isn't consistent across all the cars.
Once we have Brands Hatch Festival out of the ay, I will re-survey the Boxster owners and maybe the 997 ones too.
Simon, please send an email to Sarah at Club office with details of your car and RMS failure so she can update the survey
