Had 6 year PDK clutch fluid changed by OPC in my 2009 997. OPC advised weeping from what looks like a level bung but what they described as a bleeder screw. They tightened it but slight leak still there. They do not want to remove it as guidance says do no. They say no repair available and only solution is new PDK. Crazy? Any Thoughts? Where is the fill location for the clutch fluid. OPC very confused about purpose of leaking bung.

A couple of questions. Shouldn't the 6 year fluid change have been done 2 years ago? Presumably you don't have extended warranty? I will be in my PC on Friday and will enquire of the very knowledgeable service team there and see if they can shine any light on said bung/bleeder screw or whatever it is! A new gearbox for a slight weep of fluid would seem a bit excessive, to say the very least.
Doesn't answer your question, but there's an old Jay Leno video that shows a deconstructed pdk on the bench here https://www.youtube.com/watch?v=R0t2xia8xxs
Also there is bit on the pdk fluids on the web as follows-
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 yearsPDK clutch oil - approx. 5.49 quarts / 5.2 liters Pentosin Gear Oil FFL 3 - change at 60 K miles or 6 years.
The following procedure is from the 2009 Technik Service information book:
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.
Not sure if this throws many more light on the subject or how accurate it all is but you're welcome to make of it what you will.

Can anyone offer any advice on this please - my 2012 987 Cayman had a new PDK gearbox under warranty in 2016. It's now due for its 6 year service and the service guide requires a renewal of the PDK clutch oil at this age. Would I be right to assume that as the box was replaced two years ago then the clutch oil is only two years old and won't need changing for another 4 years?
