They said it won't work but they were wrong (Powered charge port door on P85)

    Recently learned about someone who rigged up an 85D charge port to a P85. Most of the SC's have said that the touchscreen would not recognize the new charge port and the door closing feature would not work.

    Wrong. Not only does a P85 see the new charge port but port door can be closed from the touch screen. Here's a shot of what shows up on the P85 screen with the D charge port connected.

    But this apparently is not as easy as it might first seem. There's still a question about whether the D charge port can be mounted on a pre-D car. When there's an answer it will be posted here.

    True confessions: I don't have the D charge port and I don't know who does. This info was shared with me anonymously.

    And on a sig?

    That would be a pretty cool retrofit if it wasn't too much $.

    Can you find out if a software update was required? Pretty sure it would be.

    A firmware/software upgrade is definitely not required. I asked the same question and was told it works connected to the same plug that connects P85's charge port.

    most likely the charge port door communicates with the touch screen to say what hardware it is (via CAN) and then the software in the touchscreen enables the buttons for it.

    I'd love to get that door, and I'd REALLY like to get the cold weather windshield.

    If you trust your anonymous screenshot, note that the car pictured is signature red. Therefore the question about whether the D charge port can be added to a pre-D car should be answered. Correct me if I'm wrong, but I don't think we've had any foreign launches (thus qualifying for Sig Red) since the D announcement.

    I hope there is eventually a retrofit available then. I've driven away from a SuperCharger on more than one occasion with my charge port door open. :redface:

    My next question would be: if you unplugged the 60kWh battery, then reconnected the 85kWh battery would it recognize it and work as an S85? Anyone have any extra batteries laying around to try it?

    There's a specific option code programmed into the car for battery size. That isn't true for the charge port - at least I don't believe.

    - - - Updated - - -

    I got to thinking about this. A few weeks ago, I was required to change all four of my door handles because Tesla couldn't find any of the original ones anymore - and that required me to go to the new ones. The service center called around a bit before concluding no dice on finding an older part. (I really liked the older handles, because the LED's actually shine down as opposed to just lighting the handle, and I really don't like the 1/8" of "play" that I feel when I pull. I know others prefer the new behavior, but I rather like the old, thank-you-very-much.)

    It's likely the same situation here. Tesla will consume all the remaining stock of old charge ports for the cars that still have them; then they'll have to begin installing the newer ones, keeping parts maintenance simple. I was told that new firmware was required to be pushed for newer door handles, though, although they seemed to work while he was pushing firmware.

    @FlasherZ - Indeed, every time my door handles have been replaced, the techs have flashed a new firmware or reflashed the existing firmware. It's to make sure that the embedded firmware on the handles is speaking the same language as the MCU. That's my take at least.
