When you say you can’t find out by calling Tesla, just be aware you often are talking to new employees. You won’t find any 20 year vets who know everything. If you tried a Service Center, try calling another one. If a SC is nearby, go down there and have a face to face chat. I have found that sometimes the best way to get info is to call the head shed in Fremont, although I do recall educating two employees there on some topic they probably should have known.
As an owner of two Teslas and many interactions with their staff, I will summarize my experiences as being very positive. The energy, friendliness and enthusiasm of their mostly young, inexperienced employees more than offsets the fact they often don’t have ready answers to some pretty basic questions.
This board has lots of great info, but for the question you are asking I wouldn’t trust that advice. You need Tesla to give you the answer, even if it requires some digging. Face to face chat is much better than a phone call. You don’t need an appointment for that.
