I was experimenting with launch control on my 2017 C63S. I engaged both paddles, activated the launch, applied the brake, revved slightly over 4K RPM, and released. But then, the car unexpectedly lost all power while the traction control light was blinking. It didn't stall or make any noises, it just cut off the gas. After waiting a few minutes and giving it another try, everything seemed fine. However, when I scanned for errors, I got error code P0742(86) (no check engine light). Any thoughts on what might have caused this hiccup? Should I be concerned?
