I tend not to use the automatic light feature in my 211. The reason is that whiist they work as they should, I find that they come on when I do not really need them, and stay on for too long.
I found that I would regularly have to charge the new battery when the 'no consumables' warning came on in the clocks. All of the software updates have been done, however since not using this feature I have had no problems with the battery at all. I must add that the car does a lot of fairly short journeys.
