I think you will still get that message even with a new battery.

The low battery message seems to appear frequently with these cars. I believe there is a software update available for this. I have also read elsewhere on this forum that the alternator on 2011-12 cars gives less aggressive charging to improve fuel consumption. I have one of these cigarette lighter voltmeters which often shows just 11.5v prior to start with a fairly new AGM battery. I have learned just to ignore the low battery message, and occasionally top up with a CTEK battery charger during the winter months, especially when doing a series of short trips or if using the pre-heater.

But if someone wants to shell out for a new AGM every time a low battery warning light pops up....who are we to stop them? |

I did a post about this a month ago - very strange I know but ring... Bmw! Their spares offered significantly less than lr and cp4l and is a bloody good battery! Current stable:
