BMW have not fixed the problem yet, at least not on 2010 models.
I now make sure I put it on the CTEK charger once every couple of weeks, which is absolutely ridiculous for a vehicle in this price range.
Next time around I think it's going to be a Ford, rather than a BMW.

p.s. When you use your CTEK, do you use it at the AGM (14.7 volts) setting? It is marked with the * (also for use in winter conditions)
If you charge your AGM at normal setting (14.4 volts) you will not charge your battery completely.
