My 2013 Model S VIN 13xxx MCU went dead. I was hoping to purchase MCU2, but Tesla Service Center Santa Clara is saying my VIN is too old to take MCU2 replacement, so they're charging $2200 for MCU1. Anyone know about the VIN cut off for MCU2? According to the article, they said: "All remaining Model S and Model X owners Coming Soon" (I heard April) "Infotainment Upgrade" Anyone know if the cut off is true, or are they just trying to sell up all their MCU1's before selling me an MCU2? Thanks.
