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?

It just says ‘Error Start/Stop’ where do you find the error log?

Yes there were multiple codes. I cleared them, went for an hour drive or so and the stop start was working the whole time. My battery was fine and the voltage was spot on so whether or not it was just a fault I don’t know. So far so good.
