I hve the same charger. The first one did what yours did, and I traded it back to the dealer for a new one. Now. It works like you said. It goes to the 3/3 position after being attached to the bike overnight. At that point it is done. It never goes back to charging unless the bike is turned on and then off again, and then the cycle repeats and finishes sooner. This means that I really cannot leave my bike unattended while charging as this charger does not turn on again of its own accord, due to the canbus system shutting down eventually.
I now use the regular bmw gel charger that continually monitors the float charge. I have it hooked direct to teh battery. I do use the bmw special canbus charger occassionally as it may have a better desulphating technology.
