PDK lifetime?

I think that overtime, repair costs will likely drop from what they are now (replacements of entire transmissions only), as aftermarket entrants try to figure out ways to solve these problems for less than the cost of a new PDK. Just economics, but that horizon could be a long one...Be prepared

I will post pics as soon as I get the car. And in order to do so, need to solve this dilemma.
Damn, this red C2S with PDK is so nice

But MTs have failure modes too, and their maintenance costs in the long run, I contend, will be higher (new clutch at 60K miles > PDK service). From another perspective ... Will the PDK be a cloud hanging over your shoulder that diminishes the joy of owning your car? I can't answer that for you. For me, I have grown to trust Porsche engineering. These are amazing cars in all aspects. I have trust. I love everything about my car including the PDK. For me, the answer for your purchase is to go for it! PDK or MT, you're on a fantastic path. Good luck.
On the other hand, PDK service includes fluid and filter replacement, right? If there is a double clutch in there, is there a need to replace the clutch discs?
Thanks for your help guys, this forum is amazing!

For me the new clutch at 60K miles would be a DIY that I would enjoy. Of course, would have to buy the parts.

Exactly, what is 'lifetime'. Life of the car, tranny, your life? My Range Rover had the same 'Lifteime' sealed tranny. Turns out that there was a spike in tranny deaths on Rovers with over 90k miles. People started flushing the tranny fluids at 50k. Yup....drop in tranny deaths. Lifetime means nothing, its another sealed component that needs a fluid change to clear out the clogged filters and metalic sand.

I thought the same thing and started hearing about break downs in the RR community. The consensus was to 'F' what LR said and change the fluid and filters around 50K.
When it came to my bikes (MV F4100, RC30, RC51 Africa Twin Vrod) I changed the tranny fluids every 2 years just because its easy and cheap.
Manufacturers likes to sell vehicles, 'lifetime' is a subjective term. Better error on the side of caution. A few pints of fluid, filter and seal is cheap insurance.

I changed my PDK trans fluid at 19K miles in a car that was extensively tracked (12-15 track days prior). See pic of car on left.
Car has always performed flawlessly.
My understanding is that there is also a secondary fluid that can be changed on the differential side (mechanics among us please correct me if I am wrong)... I did not change this fluid, as I figured the fluid in the main gears mechanism (equivalent to gear oil in a manual tranny) WAS changed...and this fluid protects the major load bearing internals of the PDK.
I do not believe in 'lifetime fill' anything. It is just hogwash, as anyone with any understanding of mechanical engineering, materials engineering and fluid dynamics understands... parts and fluids under severe load wear, shear and become contaminated with particles, hoses and rubber get old. These things need to be refreshed.

The factory recommends changing the wet clutches fluid at 6 years or 60k miles and the transaxle oil at 120k miles (time ?). I changed both at 5 years (25k miles).

If you only changed 1 fluid, that was the wet clutches oil. The other fluid is transaxle oil which takes care of the gears and diff, like in a manual transaxle. The factory recommends changing the wet clutches fluid at 6 years or 60k miles and the transaxle oil at 120k miles (time ?). I changed both at 5 years (25k miles).
Is there anything else that must be done (besides oil pan replacement) like programming when the fluids are replaced?
Thanks!

The seal is an integral part of the pan and is a one time use. If you remove the pan you will need to replace it.
Tony is spot on regarding the fluids.
The fill requires putting some oil in, shutting off the cooling line pump, bringing the oil to a certain temperature, and then adding more oil. PIWIS is required to do this. There is a 5 minute window before, I am told, damage will occur. Given the cost of the transmission, I was not willing to DIY this.

Re test drives... PCNA stopped entering manual transmission cars in their Porsche Experience events due to 'testers' destroying clutches. So much for those who think they are skilled manual transmission drivers.

Mine a 2009 was just replaced a few weeks ago with 24,000 miles luckily I had the Fidelity Warranty. The cost would have been $10,000 since it seems based on Suncoast they have gone down. Also had the water pump replaced and the mirror fixed all for $250.00.
