PDK Transmission Fluid & Filter Change Interval for 991.2 Carrera S

0

Hey everyone,

I've got a 2018 Porsche 911 Carrera S with the PDK transmission, and I'm approaching 40,000 miles. I've been doing some research on the recommended service intervals, especially for the PDK fluid and filter, and I'm getting some conflicting information.

Some sources say it's a 'lifetime' fluid, while others recommend changing it much sooner than Porsche's official schedule. What's the general consensus among owners here? Is the 40k-mile mark a good time to consider this service?

Also, is this something a competent DIYer can tackle, or is it best left to a specialist shop? I'm pretty handy with wrenches, but I know PDKs can be finicky. Any advice or experiences would be greatly appreciated!
