Battery Low Charge?
I just put my ignition on for a minute to check bulbs & other things as I've just bought the car, and after a minute everything switched off with a low charge warning
I had it on charge for at least 3-4 hours today, and then turned ignition on to see whether it would come on again and after a minute everything shut down again, as if charging had made no difference anyone seen this before? does the satnav drain the battery a lot? luckily most of my drives are 60 mile + so it should recharge and I'm hoping the previous owner was a town driver! |

Got the same issue with mine constantly getting the battery warning when the ignition is left on for a minute or so.....
I've tried to charge it in the boot but been told should use the terminal under the bonnet. On the E46 there was a clear earth but doesn't seem to be one on the E92?! |

I've found how to access it but I don't know where to go after that, someone compiled a list but can't see anything about battery voltage on it :/
I have found out the battery has a colour eye on it that tells you green = ok above 50% charge, black = need charging and yellow = needs replacing so will check mine next time I'm out! |

I know as I've got the same thing going on with my e90, but I think it's largely through lack of use. I stuck it on a trickle charger the other day and drove ~50 miles last night so hopefully will be solved.

i have had the same with mine since i bought it three years ago. It starts/turns the engine over nice and strong so I'm not sure whether it is the battery but parked up engine off but anything electrical on and I get the low battery message then shuts down. Mine doesn't get short journeys either, virtually all of them are 25miles plus so should be plenty to re charge I'd have thought.

ours does that
battery is not holding sufficient charge and needs to be replaced, BMW say this is normal and a battery life of LESS THAN 3 YEARS is acceptable a new battery will costs loads plus coding, battery places dont want to do the job so its a specialiest or a dealer job

Same problem a month ago.
Car is from 2006, same battery since. Got a new bosch battery at the end £110~ 85Ah. Specialist coded it, to 80Ah. Oem only has 70/80/90 sizes plus the AGM equivalent. Not a problem since, been and back from Germany. All lights working fine and no more warning messages. |

Mine did that - it was on its original battery and its a 2005 car so its done a good 7 years, i changed it for a nice bosch one from Eurocarparts, cost me £45 inc 30% off (they had an offer going on at the time) and had no problems since. When i changed mine i didn't need anything coding.............it was a 10 minute job if that.

The battery coding is supposed to alter the charge rate firstly for the amp/hours e.g. 80,90 A/Hrs and secondly alters the charge rate for the age of the battery to maximise battery life. I take it that means that the charge may be more aggressive whilst the battery is new and tapers the charge as it gets older and more fragile.

I had this problem when I bought the car. It seems to be quite common from what I have seen on this thread. I charged it for about 24hrs on some special proper meaty digital charger I borrowed from the garage (which apparently cost £2,500). Then I disconnectd the battery for 30 mins (do not let the boot shut) reconnected and not had the problem since. Also I do quite a few short journeys.
I think in my case it just needed to be fully, fully charged. May be worth a try |
