This is pretty discerning if true. It could mean something in the FDU running dry and could be wearing out prematurely.
The cold makes oil more viscous and less likely to splash around and coat everything well. Theroteically they should've designed it such that this wouldn't' be a problem but who knows.
Very interesting on the left incline, that would make some sense. The difference is when I take that hard right exit, the noise comes back almost immediately after leaving the turn. Sounds like the nosie went away for a while with Dadaaaaaaa's incline. Maybe it had longer to soak in?
Replacing the oil doesn't actually look that hard. Granted I'm not sure if I want to risk Tesla claiming it was messed up and invalidate any future powertrain warranties:
