The throttle body is electric and BMW recommends against cleaning it with any cleaner. It may only require calibration or possible the electronics were damaged when you cleaned it.
Low battery voltage can will cause a no start condition due to the starter drawing all the voltage and not enough for the control units to start it. If the battery died after sitting for three weeks I think you will need a new battery.
