Neat to know that trick, but that is a crazy thing to have to do and wait for lol. Sometimes I don't get updates for weeks at a time maybe even a month or so can go by, so not really satisfied with that approach long term. Yeah I ended up losing money slightly by installing the part locally then going to Service Center when the part replacement didn't get rid of the error messages. Was a crappy ordeal, not to mention 4 hours of driving between taking my car to the closest service center and getting back home. Once they get a Service Center in South Carolina it may not suck as hard but it seems to not be a priority for them(I think we have local laws preventing a service center at the moment because there is no "dealership" here, sold old auto law the big money ICE companies put in place with their old dealership sales model). With Tesla now having bankroll from shares skyrocketing I would think they could pay off the politicians and get me a service center somewhere in the middle of South Carolina or the Upstate.
I'm trying to make sure because I am about to replace my battery heater in my own garage. Did Tesla tell you that they would not update your car for you when you replace parts yourself? Maybe it was just the way it worked out for you, since you didn't know you needed a software redeploy until you were in the service center and they had already spent time diagnosing your car. I'm just hoping that I can get a remote redeploy without charge (or minimal charge) once I replace my battery heater.
