Need help from the experts. How do I know that my ECU was updated for sure after the recall? I ask because I had coding done on my car months ago and it's still intact. Furthermore, wouldn't I have to sync my phone contacts (Bluetooth) again? My phones remains synced to my idrive when I got it back.
Is this software update such that the aforementioned are not affected?
This is what part of my invoice says:
"Tech 115 reprogrammed car, including CAS, rescanned after programming, reset steering angle sensor."
