As well as the variable start up times for the infotainment system on second start of the day sometimes, I’ve also had another issue twice now over the last 6 months.
The car just won’t connect to the phone, wired CarPlay, saying no connection possible.
I’ve tried restarting the phone and restarting the car but no luck - when the issue happens the car and phone won’t connect.
The only thing I can do is move the usb cable to the power socket and then try again later after maybe 10-20 minutes, when it works.
Obviously some bug to do with CarPlay and the infotainment unit, but as it happens rarely it’s likely impossible to find
