Well you already know you overheated your car, and that fault is what set the SES light. Clear the code, and if will probably will stay away.

But BMW motors don't take kindly to overheating, so you'll have to keep a close eye out for symptoms of a damaged head gasket or even ruined cylinder head. From what you've said, it seems that neither is the case, but you need to really keep a close eye on your coolant level and your temperature gauge for a while.
