PDK oil service
I have a 2003 Boxster S with 28,500 miles.
I have read that the PDK transmission holds 9 liters of oil, yet a service change requires only 3.5 liter replacement. I have no idea if the transmission service has been performed, but I suspect not. It works fine. I have read cautions of mixing oils and refreshing only 1/3 of the oil seems off to me. I am coming onto my 30K mile service and want the trans oil/filter changed. Is it the normal maintenance procedure to do a filter, gasket and 3.5 liter of oil or should I insist on a total flush and refill of 9 liters? |
Hmm. The PDK wasn't available until 2008. Assuming that you meant 2008/PDK, then there are two types of fluid that are used in the PDK gearbox:
PDK transmission oil - approx. 3.12 quarts 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 Pentosin Gear Oil FFL 3 - change at 60 K miles or 6 years Looks like you need the PIWIS to perform the check after refill. 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) This is a good link: PDK / Gear oil - 997-2 Series (Carrera, Carrera 4, Carrera 2S, Carrera 4S, Carrera GTS, 911 Speedster) - RennTech.org Forums |

Thanks, Thstone, for the info. My initial post shows how new I am to the Porsche world. I should have said my Boxster has a Tiptronic auto/manual transmission. Any advise for me now?
