Bought brand new charge port for P100D year 2017. Part number: 1061353-00-F. The old one is mechanically damaged, albeit charging works but in limited mode. When charge port physically changed: The car says "Software upgrade required". Port will not unlock Doesn't charge if opened via emergency charge port release lever Plugging back old charger works. And it does NOT say "Software upgrade required". I suspect it is due to software incompatibility that the new port refuses to work. I'm now on 2018.48.12.1 d6999f5 and I think soon I will be offered a new firmware upgrade. However i'm afraid plugging in new port and upgrading firmware and hoping it will upgrade my new port. If software goes out-of-sync with old port, I may have no option to charge (if there may be other issues with new charge port). What are my options? Is there an option to manually update Tesla (charge port)? Are there anyone who services his Tesla by himself? How do Service Centers do it? They are provided with software from Tesla or what? Can it be used by car owners? I'm a software engineer myself and if there is a way to load that update by myself, that would be great. In my country where I live and neighboring countries there is no Tesla service center The closest one is I think 1200km.
