Throttle hesitation after jump start (MY'05 E55)
Hi everyone - I made the mistake leaving my headlights on draining the battery three days ago. 
I jump started the E55 but did not follow any of the resynchronize procedures (ESP, windows, moonroof). I took a short drive and the following cluster messages appeared:
I drove home after work with no issues and the following message appeared by the time I got home:
The issue I'm experiencing, however, is that when I depress the throttle pedal under heavy acceleration, it hesitates and it feels as though the S/C engages/disengages intermittently. Basically, it feels like the car is in some sort of "limp" mode. But normal granny driving seems fine though. 
I'm likely guessing I will need to reset the ECU/TCU via Star, clear any codes, perhaps I need to disconnect the battery and follow the resynchronize procedures? Your help is definitely appreciated!

Conv. battery is the small battery in the engine bay just below the filter of the ventilation. When you open the hood, facing the car, on your left hand side up on the corner.
