@PV997 Just reaching out for your expertise on PDK if you don't mind. Trying to get a sense of the fluids that need to be changed. I had the PDK clutch fluid and AWD controller fluid done in 2020 at 57k miles (car has 72k miles now - 997.2 TTS). I know the PDK Gear oil and Differential gear oil needs to be done every 12 years....Do you have the fluid specs for that? For diff are the front and rear diff oils changed? I am seeing it is Mobilube PTX 75W90 but just looking to confirm that it's the same for both.

Also do you recommend doing the PDK clutch fluid again? This needs PIWIS from what I can remember.
Thanks in Advance!
