Check engine!!! Please advise

I have 2012 e63 with a P30. Last Friday i removed the resonator and installed straight pipes. Drove the car Satrday, Sunday no problems. This morning started the car so it warms up before i leave for work, check engine light comes on..... Drove the car later for 25 miles to work. Now 2 hrs later decide to go and start the car in the parking lot to see if any more issues but now "NO Check engine light". Any advice what the reason???

Hopefully it will go away by itself. If not, obviously MB service is where you are heading next. I wonder how MB service will respond to the resonator delete.
