Might as well keep all of the electronic gremlins in one thread...
I have noticed now the weather has changed that non-warm dry summer seems to yield more bongs.
This week I've had several different things bong on startup and fail.
I wonder if the issue like that isn't that the various system controllers aren't cold and sluggish and don't start fast enough, throwing an error.
Things like parking sensors, dynamic lighting, front assist.
We all know computers are actually slower when cold (its physics) so i wonder if thats the cause of the startup bongs.
Of course when you get somewhere, stop and come back to the car, everything is sweet... which does suggest temperature.
The controllers don't seem to recover other than a total car shutdown too... which is a pain.
