I'm having an issue with my 2017 Model S with FSD.
AP and CC are not available sometimes and SC is not able to diagnose the problem but they propose to change the ECU (AP computer), which is around 2.000€ and my car is out of garanty
In my opinion the problem is MCU related because when AP/CC are not available, I always get the next error in service mode "APP_w189_backupCameraStreamExit".
By the way, backup camera works fine in reverse, but I have noticed that when I select reverse, it my take up to two seconds to show the picture in the MCU.
When I drive the car for the first time in the day, AP/CC are never available, but for the rest of the day it works randomly. When AP is not available, I can see my car and the road line in the dashboard but not the cars around me.
I have also noticed that MCU2 sometimes runs slow, TuneIn is buffering more than usually and even I hear some pops coming from the speakers.
Any help would be very much appreciated.
