Try this BMW approved procedure:

- remove the ground (-) lead from the battery
- remove the positive (+) lead from the battery
- short the leads together for at least 10 minutes (hint: place the leads against the metal battery hold down bracket)
- reconnect the positive (+) lead to the battery
- reconnect the ground (-) lead to the battery (yes, there will be a but of a spark)
