In case anyone out there with MCU reboot issue, hope this helps
My car is a AP1 2016 Model X 60D with 75D upgrade.
Over the past few months, the MCU started to reboot on its own occasionally. It got worse over time, from once in a while, once every few days, then few times a day. to every 10-15 mins. I couldn't stand it anymore, i decided to take it in to service.
1st attempt - dealer applied new software update, it worked for a few days and the same issue came back in a few weeks
2nd attempt - this time they kept the car for 1.5 weeks, they determined it was the bluetooth phonebook that was causing corruption in the system. suggested I do not sync phone book until further notice. ( i use an iphone x, no funny names in phone book) . They did a full reset on the MCU / car. no more reboots so far, I drove the car for about 2 hours today and no more reboots. it was rebooting every 10-15 mins before.
I also had the driver side window regulator replaced the 2nd time, due to excessive noise.
so if you happen to experience above issue, try resetting your car to factory settings and do not sync phone book via bluetooth. maybe it will save you a trip to service.
