Not quite.... The charging voltage is dependent on the battery temperature and FL2 system is pretty well designed in that matter. Up to 15V when sub zero outside and down to 13.5V when very hot. In fact, the battery charging voltage is dictated by the engine ECU which approximate pretty well the battery temperature from ambient temperature and intake air temperature. And as a side fact my CTEK indicator is always green after about an hour since locking the car. So over 12.6V. |

That's interesting - I am aware of increase in volts needed when (very) cold. Didn't think FL2 was that clever (or any car TBH)

About the same as ours - low enough mileage to have had short runs which will drag the battery life down. Although it runs really well - it does not feel like it's been given a lot of short runs. Knowing where they lived and nearest supermarket, shortest regular run was probably five miles - just enough to get warm I guess. About the same as the shortest and regular runs we do - wasn't sure myself if this is enough to keep DPF issues at bay. |

I get the message when I've been sat for a while listening to the radio. I get the normal shut down in one minute message a couple of times and then the low battery message. After it first happened I connected the CTEK when I got home and it went green very quickly. I just think the system is over cautious and I now just ignore the low battery warning. Two years on and I seem not to have a battery problem. It's just a minor irritation I can live with. driving on the right side |

Many thanks anglaslt will try to ignore it but after last FL2 it has me doubting everything Was getting the message every time then car wouldn't start, after many many rows with stealer it was found to be some *electronic gadget* it passenger door had packed in ( took them 3 months to find that out)

Well certainly on mine when listening to the radio it says it will "shut down in one minute" about every 10 minutes or so. I just turn it off and on again. With the low battery warning it is needed to actually run the engine othewrwise the radio will shut down and cannot be turned back on.

if your car has stop start it should have an AGM battery,if it hasn't the battery will soon die! |
