I turned it off, then restarted it again and still the light did not return. My reasoning for trying that was because I thought maybe since I reset the adaptation that the car didn't know what the limits of the throttle pedal were anymore. Not sure if that's what it was or what but the light hasn't come back since. I still can't access the DME/DDE for clearing adaptations anymore but for now I'm just not going to worry about it.
what you did here is also a way to reset the throttle adaptation (apparently)
so might have done the trick
