My new to me 2015 CPO C4S has PASM+PDCC but the build sheet does not list that option. I know that all 99.1 S versions have PASM as standard but PDCC is definitely an option. I am assuming that PDCC was installed on the car either at Trophy Performance in Nevada or at Ralph's auto service in Maryland based on Carfax history. Do you know if PDCC retrofit is possible on a PASM 911 and are you familiar of any of these two independent Porsche service centers ?
Thanks!
Thanks!

It would be quite a bit of work.
If you want to explore to see if it's installed remove both rear fans and see if you have what looks like a brake reservoir cap just to the right of the coolant and oil caps.
This is where the fluid bottle and pump are located.

Does the button have the same detent and click sensation? Do you notice a difference with the PDCC on and off.? Check for the reservoir as described above. You check your vin in vinanalytics.com? Your dealer when given your vin will be able to tell you replacement parts based on what your car specifically has.

Have you pulled the engine cover and removed the fans? It’s a 3 minute job. Should provide the confirmation that you desire.
If you haven’t yet done this, here are instructions:

If you have in fact 'scored' a 991 with a PDCC retrofit then you should put the previous owner in your will.
Retrofitting PDCC would be very expensive. Off the top of my head: $30k+ parts and labor. PDCC is composed of hydraulic sway bar drop links, the hard fluid lines to each, a belt driven hydraulic pump, several valve blocks, fluid reservoir, probably a different suspension control unit, and here's the kicker: a bunch of wiring harnesses. For a while now, wiring harnesses aren't made to a one-size-fits all template. They are bespoke based upon options. So, if your 991 didn't leave the factory with PDCC it's not wired for any of the components.
It's certainly possible. But, if *I* liked a specific 991 without PDCC so much that I'd spend 10s of K on a PDCC retrofit, I probably wouldn't ever sell it.

Build sheets are sometimes incorrect.... Not frequently, but it happens. And Vinanalytics just back-doors the "official" PCNA computer database build sheets, so they will be the same.
Not sure if the "really official" Porsche Production Specification (what used to be called a Certificate Of Authenticity or COA) might be more accurate, but it will cost you $110 to find out.
I think that is far more likely that the build sheet is incorrect vs. someone retrofitting PDCC to your car. Or that you really don't have PDCC, but someone simply swapped in a PASM button with the PDCC screening, which would cost about $30. It is an identical switch, just different graphics.

I would have guessed that the wrong button was used. It’s a lot easier and cheaper to install a button that says PDCC than it would be to retrofit.

Did you pull the fans yet?

I forget the details but there are threads that talk about how to identify physically if the car was equipped with PDCC.
