hi all
any help or info appreciated
2 days ago i was idle with the engine running for 1 hour at least.
i a message popped up on the dash
stop vehicle leave in park and leave engine running.
now after a bit of research it seems its the auxillery battery gone or on its way out.
there are no symptoms
as in everything works absolutely fine. all 12v ports work with no defect
lights work fine
car doesnt struggle to start
but only the start stop light stays yellow and doesnt move over to green light which is activated
there are no others problems
wonder if anyone has had same issue and would know of a solution
 
It could be that if you take the car for a really good run the aux battery might recharge up sufficiently to get the stop start working. However they are not expensive to replay as far as I am aware
 
Replace
 
It's about 350 to replace main battery and 250 to related the auxillery

Not exactly cheap but could be worse:rolleyes:

Go to somewhere like F1 Autocentres and prices will be half that even for good batteries like Varta.
 
Just an update on this issue I replaced the battery after the start of the post. And once again the battery sign has come up again. I haven't left it idling like I did before always switched off if I'm stationary. My thought is the axillary battery or capacitor. Any suggestion on this
