It looks like you need new 02 sensor (pre one),

2nd fault is dump valve related check recir dv and its piping are tight

Hope you mean recirv or diverter valve, you cannot run a BOV hence the fault and lumpy running.
Its before the cat you need.

you can run a bov thats rubbish, the cars been fine with it for 2 years just the last month its playing up hence sensor failures. plenty of people run atmospheric dv's on here with no problems, but thanks for the help though!

so all 6 of these codes relate to the o2 sensor before the cat ie towards turbo end (would a de-cat not corrupt this?) and a the maf? thanks
