Cayman jacking and oil change questions

[s_morrison57]

Hi
A buddy of mine bought a 2010 Cayman S with the PDK, I'm green with envy but the 930 will have to do. Last year I started looking at Boxsters and bought the 101 projects book, I lent the book to my bud and he had a couple of questions and since he doesn't know how to work a computer he asked me to ask.

Wayne says that the 101 book works 90 to 95% on the Cayman, are the jacking instructions the same to get the car up on jack stands?

How often do you Cayman and Boxster guys change your oil? My buddy and I cringe at the manuals 15K recommended change intervals but we are old school, does 5K sound ok?

Anybody change the oil in their PDK yet? Is there a filter in the tranny?

Thanks for helping out my old geezer buddy.

From the manual, it looks like you need access to a PIWIS:

PDK transmission oil - approx. 3.12 quarts / 2.95 liters ATF transmission oil Mobilube PTX Formula A (SAE 75W-90) GL 4.5 - change at 120K miles or 12 years

PDK clutch oil - approx. 5.49 quarts / 5.2 liters Pentosin Gear Oil FFL 3 - change at 60 K miles or 6 years

Oil filling
The correct hydraulic oil level is important for operating the transmission without
running into problems. The following preconditions must be met in order to check or
correct the oil level:
• Engine must be idling
• Vehicle must be horizontal in both longitudinal and transverse axis
• Hydraulic oil temperature between 86° F. and 104° F. (30° C and 40° C)
• Selector-lever position “P”
• Clutch cooling volume flow must be switched off (using PIWIS Tester in Oil fill
mode)
• Retain the described states for approx. 1 minute to allow the oil to settle
• Open screw plug on oil overflow bore and collect emerging oil until only drops of
oil are emerging
• Once there is no more oil emerging, top up the clutch fluid until oil emerges at
the oil overflow bore
• To avoid damaging the clutches, the procedure must be completed within 5 minutes
(PIWIS Tester exits Oil fill mode automatically after 5 minutes)
The correct oil level is also important to avoid damaging the gear wheels in the
transmission. There is also an overflow bore for this, which is located on the opposite side. The oil level can be checked in the usual way here.

DO NOT CHANGE YOUR PDK TRANSMISSION OIL.
As a shop owner and former dealer tech, I enjoy the content that gets passed back and forth that ultimately ensures future business from DIYer's. But please, I have to interject, why is this an issue, PDK transmission oil? You see the above procedure; even at the dealership, the conditions to complete this service were difficult to duplicate. The one time I had to do this, it was a warranty job, based on the field technical manager's call. The fluid wasn't even available in North America at the time. If you are using synthetic for your engine oil, changing it less than 10k miles intervals is waste of money.

I find your comments on changing oils, engine or transmission “enlightening” to say the least, Setting your comment about engine oil change intervals aside, I would note that the very first thing the three dealer’s near me do with a misbehaving PDK is change the fluid, then the software, then the gear box……………
