Hello all I'm am new here a bit of history I have a 2013 Model S 85 kwh I am in the Toronto Canada area. I bought the car used back in 2017 with 57.000 km's and now it has 160,000 km's the car still had some factory warranty when I first got it and I did have the MCU replaced in October 2017 for a fan noise so it's still an MCU v1 but now has LTE functionality.
Here is the problem .......last week I was showing a friend of mine the car and when I swiped up from the bottom of the screen it went black I thought it's never done that before maybe it already has the eMMC issue I have been reading about so a quick double scroll wheel reset and it came back to life with everything working 100% the only thing I noticed is my mobile app is not working anymore my phone connects to Tesla server but the server can not connect to my car I called Tech support and we did all the usual re-set procedures double scroll wheel reset and power the car down uninstall the app ( iphone app ) reinstall and log back in still no connectivity it was suggested it may be a firmware problem and I should go to the service center to get a firmware update installed. I was at the service center in Toronto on Oct 24 for the day and the end result they say I have to replace my MCU I declined as everything is still working 100% all functions music streaming Bluetooth live map data I mean everything. So after another phone call to Tech support we reviewed what was done on the car and it was reviled 2 updates were pushed and failed so he had me hot spot my phone with the car and tried to reach my car on wifi and still no connection........Ugh.......does anyone know what mechanism is used by the MCU for output communication to Tesla's mother-ship server what could be broken ? all incoming data services are fine just the Mother-ship can not communicate with my car anymore so no more data logging and no more updates. I really want my mobile app function back.. Sorry for my very long first post any help is appreciated.
