Salvage free unlimited supercharging account transfer

[kagy]

I am the owner of a 2013 tesla model s 60 with a salvage title. This car has free unlimited supercharging but I'm not sure if SC01 or not. My problem is when I bought the car the old owner was logged in on the car. I'm afraid that if I log out of the car via factory reset I will lose the free supercharging entirely. I want to use the mobile app for my car that's the only reason I am even considering this. I want to contact tesla SC about this but they need my vin to check. If they see my cars vin and it comes up as salvage they will most likely disable supercharging anyways. I'm fine with paying the tesla SC to recertify my car but I don't want them to take way the free part of my supercharging. Any idea's on what I can do? Also no way to contact previous owner.
