When was your car produced? Mine was built late December, and I have the 9J1 035 070 hardware.

Again... "PCM 6" is the platform. We all have PCM 6. What changes is the "Central Computer" hardware as well as the PCM software stack. To date all Taycan's shipped have hardware in the H91J035 family including early 2022s. There is a new hardware revision coming for new 2022s that has prefix PAD. What the service rep said makes no sense at all, so something was either lost in translation or he's an idiot.Hi Folks,
It appears Porsche employees have a secret forum of their own not accessible to the public. Bringing my 2021 4S in for it's THIRD recall/update campaign (improper flasher activation on close fwd collision warnings and replacing all 3 AC pressure sensors), the service rep said PCM 6.0 will be installed in 2022 Taycans assembled in the second half of this year sometime. PCM 6.0 is not backward compatible because the hardware on vehicles assembled before that cannot handle PCM 6.0. He learned this on the aforementioned forum. FWIW.
I really love this comparison for both!So if you want an iPad on wheels. Get a Tesla. If you want something that drives like sex. Get a Porsche. But don’t expect either to do what they don’t love, well.
If I translate this to:Hi Folks,

Same with mine. Also ties in with what the dealer confirmed to me earlier that the software update was only applicable to newly built vehicles (with new hardware).PCM hardware cutover update:
My car went into production today (15FE) and I did get my VIN. And using @lpher’s technique of checking the PCM part number, confirmed it is the “PAD” hardware vs the “9J1”.
Sorry, but I don't believe this will be such stupid plan by Porsche. like: H9J1035140AG(Asian HW), The last char for HW part number stands by "HW small revision", and the 2nd last char is "HW big revision", 3 digits before that was region code, so you can clearly see latest HW big version is "A", and it has been upgrade from C, D, G, H. This is the way how HW development goes. I believe for "old fashion" company like Porsche will follow such kind of traditional development cycle of HW. I don't believe they will dramatically change the HW parts, which have no benefit to them, only big complains from customers.If I translate this to:
“rep said PCM 6.0 “PAD part number prefix” will be installed in 2022 Taycans assembled in the second half of this “model” year (meaning February) sometime. PCM 6.0 “9J1 part number prefix” is not backward compatible because the hardware on vehicles assembled “with” that cannot handle PCM 6.0 “PAD’s updated software”.
it makes since to me.
does anyone have a VIN built after January 24th they can check for PAD?
Could be yeah. Just because the new software is coming first on the "PAD" prefix hardware doesn't necessarily mean it can't come for the H9J prefix hardware. It could be there are other design reasons they've updated the "Central Computer" significantly enough to go from H9J to PAD. The other thing is, depending on what the parts map looks like, it's not inconceivable that PAD could be retrofitted into a 2020/2021/early 2022.Sorry, but I don't believe this will be such stupid plan by Porsche. like: H9J1035140AG(Asian HW), The last char for HW part number stands by "HW small revision", and the 2nd last char is "HW big revision", 3 digits before that was region code, so you can clearly see latest HW big version is "A", and it has been upgrade from C, D, G, H.

and besides, as a software engineering guy for 20+ years, I don't believe changing color of icons and install a "Spotify" will need a totally new HW machine...
Stay tuned, I truly believe, most of the existing taycan owner will possibly get new SW upgrade from technical point of view. Maybe older HW(versions before "A") will have some problems from performance point of view. but I think version "A" HW should be totally OK to install new SW.
