Another hdi question - battery light

[DTubZz]

Hi guys sometimes the battery light stays on faintly for about 4 seconds when I switch the ignition off it is dimmed down though and that battery is in good condition as far as I know never fails to start, just remapped it and didn't use a power pack last week and my voltage stayed at around 12.3v all the time.
Anybody know what it means? Or is it just a French thing?

Same thing happens on mine??
Interested to know also if this is just common and not a problem??

Yeah I can't remember it happening before last week oddly, everything seems ok but like you say is it an issue

Mines Still doing the same thing but car hasn't stuttered or anything so gather everything is ok
