This lead to Mercedes changing the O2 Sensor and then the LH Control Unit at great cost. Despite this being a relatively fast job I was made to wait a couple of hours more as apparently they had trouble “dialing things in”. I was never happy with the car after that.
It's possible you did not get an exact equivalent to your old ECU but a "nearest equivalent" resulting in a slight sensor/ECU mismatch. Have you any documentation relating to the ECU change --part nos etc------what was involved in "dialing in" the new ECU? This may not be relevant but the history should be checked.
