"Battery dead" 2012 Peugeot Ion

[kiev]

Do you know the condition of the 12-volt aux battery--is it the original or has it been changed out recently? a weak, old or worn out aux battery can cause issues such as this. If it is the original, it is likely worn out and should be replaced, even if it shows 12.5 volts with a multimeter.

I have the car back and it suddenly works. Not really reassuring... Time for some testing for real!

"Did you get the Ah figure from the first screen ? That one is of critical importance and will give you a good idea of the overall health of the pack."

Do you mean "Ah History"?

No, Ah is at the bottom of the very first page with the Wh/mile driving statistics etc.

If you don't see it, tap on the left hand side of a blank line to customise the display data and choose to add Ah to the display.

The Ah history graph isn't that useful as it's just a bar graph that is too coarse to show the precision needed.

Update!

Strangest thing, no problem anymore!!!

So I went from 18000 euro battery replacement offer to a 100 euro "repair".

I did drive through some, not so deep, water. Could that have caused the issue?

I'm happy again and know where to find you guys and girls in the future. Thanks for the help!!!
