I just bought a new Model S Plaid and am selling my 2016.5 Model P100D. The old charging cable charges to 40 amps as opposed to the new cable's 32 amps. I don't want to give up the 40 amp capability of the old cable so I figured I would keep the old cable and send the new cable with the old car. I tested the new cable on both the new and old cars and everything seems to work fine. Unfortunately when using the old cable on the new car, I am no longer able to open the charge port door by pressing the thumb button on the charge cable handle. What's up with that? Once I get the charge port door opened, charging is no problem but this is going to be at least a bit of an inconvenience. Anyone know a way I can get the old cable to open the new door?
