The GOM takes some number of cycles to update to new conditions, as it seems to be influenced heavily by historic data - my case about 2 months, but I only use typically 50% of the battery over 6 days, so yours perhaps 2 weeks?
As for the fault code, you should take it to the dealer, even if the fault lamp has extinguished, so that he can extract the historic data and record it against your car's service record. Then, if it recurs or an allied fault surfaces, you have a case for getting it fixed under warranty, even if the period is over.
