Hi all,

Im struggling with a Stop/Start error at the moment. The error has been on for a while now but I’ve ignored it. Now that I’m looking to return my car I need to get it sorted.

Strangely (or not), Stop/Start is avaliable when the ignition only is on. As soon as I turn the engine on, the error appears and the Stop/Start option is greyed out.

Any suggestions on a fix?
