The MCU is not in the screen, so no, the glass protector is not a contributor. The MCU is behind the back of the glovebox as it’s been described to me.Just a quick update, the MCU was successfully replaced by my local Tesla SC. I am happy to report the quality of the service I received was outstanding! They replaced the MCU within 2 business days and gave me a rental car to use while the part was being shipped and the service was being completed. The service rep was in frequent contact with me. I believe Tesla has improved the quality of their service and I wanted to share the good news.
In terms of why my MCU failed and had to be replaced after only 2.5 years, I was curious about the following two possible factors:
1) I never used cabin overheat protection before. My car is parked outside and can often reach internal temps of 140-160 degrees. Could this have contributed to an early death for my MCU? Should I go ahead and use the cabin overheat protection to reduce the risk of any damage to my new MCU?
2) Early on, I applied one of those glass screen protectors to prevent the glass from being scratched. Is it possible that this extra layer of glass could act like a piece of insulation, trap heat inside the MCU, and contribute to an early demise? If so, I will forgo a new screen protector.
I welcome any thoughts so I know how to better protect my new MCU.
