Newer motors have a concept of "permanent code" you can't clear but they don't set the M.I.L. they will auto clear after the fault is fixed and enough drive cycles have completed.

I think you can run the adaptations before starting the motor key on engine off but also I think the n55 calibrates the Valvetronic every run cycle.

I'm curious what process you used to run the motor through it's paces
