Does anyone know how I would go about upgrading the PCM software on my 2017 911 ? I called a Porsche dealership today and they said they only perform upgrades on models that are from 2006 and older.

Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

What PCM /SW version do you have? I know there are some disk images floating around for the PCM 4.76 SW version, which is the latest for the PCM 3.1 .

Not sure...can you tell from these images? Thank you

You didn’t mention what specifically you want to upgrade for? What exactly are you hoping to accomplish by doing this, even if such an upgrade was possible? About the only thing that Porsche typically offers upgrades for are the maps, and that can be expensive with a dedicated disk that you have to purchase and then pay the dealership to install and activate it for you. It can easily cost 3 to $500 just to update the maps. Porsche charges for every little insignificant thing or feature that is standard on even the cheapest econobox car. It’s not as if you can update a system that is a few years old and magically have access to features being sold on the newer models

Valid points ...I'm the type of person that always has to have the latest version of anything so not trying to accomplish anything specifically especially since my system runs rather well with the occasional crash when listening to music off the USB drive. I contacted Porsche and they said they only do PCM upgrades on vehicles older than mine.

I’m in a 14 Cayman so it may be different. Try Info button, options tab, system version. Shawn in VA (USA)
