Hi everyone, got my first car a while ago (2013 Corsa Black Edition) very happy with it but one of two issues has been the start stop. I've never experienced it work once, and going through the list of requirements im barely able to come up with a reason why! The main cause for concern is the battery, which for some reason does not appear to be a start stop agm unit, although strangely its from halfords and they recommend an AGM battery. Can the car really tell the difference? I would expect it to at least try in this scenario, although going through the list of all other possible causes there doesn't appear to be any other fault. Thanks for any help!
