I don't know how much of a conversation with an AI will come through with this link below. I am sharing it for those who might be interested in this problem.
https://www.perplexity.ai/search/5dd27e34-a1ac-4607-bc8c-ec234a2d76b0
Summary below:
I did some further testing over the weekend. Tesla has more modern chargers (SC4s) in Los Osos and Morro Bay. I tried the one in Los Osos and ran into the same "Unauthorized Vehicle" brick wall even though I could hear the 'pump' motor spin up.
However, their newest station in Morro Bay is one of their "Magic" charging stations. These only require an adapter and a Tesla account. You don't need to be an authorized vehicle. At the Morro Bay station I didn't have any problem charging my car. *** That's great news *** tempered only by the fact that these "Magic" stations are currently rare in California.
Anyway, I think my success in M.B. rules out some hardware problem with the Taycan's high-speed charger other than the possibility of some handshake issue that is as yet undiagnosed.
I put all these details to my AI and got the following:
"Putting your details against what other owners and dealers are seeing, the most likely explanation is:
• Your 2021 Taycan’s VIN/software combo does not fully match the current Tesla–Porsche authorization profile for SC3/SC4 non‑Magic‑Dock Superchargers, while some other Taycans (likely different trims/years or updated cars) do.
• At the “any EV” station, you’re going through a more permissive path that relies mainly on Tesla app session + generic non‑Tesla rules, so it works.
"In short, you’re hitting a narrow, implementation‑specific bug or gap in the Tesla–Porsche integration, not a general VIN database problem and not a user‑level mistake.
"The next high‑value move would be:
• Ask Porsche to confirm, in writing, whether your specific VIN and current software level are marked affirmatively as “Tesla Supercharger enabled” in their systems, and
• Ask Tesla charging support to pull one failed SC3/SC4 attempt by timestamp/stall and tell you the exact denial code and whether your VIN or vendor tag is flagged as “not authorized” for that stall type."
