The light came on and stayed on until I found a safe place to pull over and shut down. I started back up again and it was gone off. (I read that on a thread here). Everything was back to normal.

I'm scheduled for a Trans fluid change and Oil change next week, so I haven't decided if I'm going to tell the dealership, since I don't know if I trust them yet.

I'm a BMW tech, here in Aus, and I've seen three 1 M coupes come with this issue, over the past 6 months. All standard and running 98 octane. In all cases found it to log to faults, super knocking and boost pressure cut out. Which can possibly be cased by bad fuel. New knock sensors under warranty have fixed the issue with ever one. Don't see any other major faults with the N54T motor
