I recently purchased a new Model X P100D a few months back with VIN 5YJXCBE47HF039565 and it came with the standard charger. I wanted to upgrade to the 72amp charger and got one from the forum here from another member. I was told by Tesla that it can not be installed due to a firmware conflict? Can anyone verify this, or is it simply that they can not guarantee it will work? I would really like to have the faster charging at home as I do on my Model S. I have a HPWC with a 100A circuit so no issues there. Trying to understand why a 100kw battery wouldn't be able to accept a 72amp charging unit?
