Front collission warning, cruise and AP stopped working

[Glydadx2]

Got in my M3 yesterday and I had non functioning front collision warning systems, cruise control and auto pilot. Tried multiple soft reboots (pressing both steering wheel buttons) and still nothing. After I got to my destination I did a hard restart (both steering wheel buttons + brake pedal) and the systems came back.

Ever happened to any of you before? Anything to worry about? Should I be contacting service?

You need to drive up to 100 km for the drivers assistance features to calibrate when the car is new.

It's unclear from your post if they were working and then stopped, or if they just hadn't started working *yet*.

Depending on what software version you have I've seen the autopilot system crash and reboot, i would probably say your fine and don't need to worry about service unless it keeps happening, what software version is currently on your car

Car is not new (purchased in Sept 2018). I am running sw version 2019.16.2

Apparently reset doesn't restart the autopilot computer. Possibly hard reset might do it. But the one thing that's really supposed to do it is the car going to sleep. But the car won't go to sleep if you use sentry mode all the time though. So they recommend periodically parking car without sentry mode at some location to trigger a reboot of the autopilot computer if this is an issue.

I haven't enabled Sentry mode (no USB stick in the USB port) but good to know. I am guessing the hard reboot does in fact reboot the AP system as it immediately started working after that reboot.
