Sorry,
Miss read. Code reader may not help. I'd try & find out whether it's a fuel or spark prob. When your car cuts out, will it re-start? If not, take lead off & see if there's a spark. If not, at least you then know it's an electrical fault, rather than fuel. Vise versa for fuel prob. Again guessing, could be fuel filter.

You need to get your car code read. You can buy a diy code reader for around £20. Or take it into a none Vauxhall garage for a diagnostic check, usually around £30 (fleabay).
Otherwise it's just a guessing game. You could try cleaning plugs & see what happens. May be your EGR valve, which is a quite common fault with eco's.
