Stop start system, not stopping anymore.

[pompeyrodney]

For the last few months my stop start system has ceased to function. For a short while whilst it was still working I was getting a message saying I had to restart manually, but since then it has ceased to function altogether. A friend suggested that my issue might be related to my battery but it is not showing any other issues to suggest an issue. Please advise what I should be looking at to isolate my issue. Many thanks in advance.

I would start with replacing the battery. Most time if the battery voltage is below a certain level it'll prevent the auto start/stop from working.

Thanks for the suggestion but I would rather know what the "certain level" of voltage should be in order that I can test the battery first.

Typically any voltage below 10 is failing.
