Thanks for the reply. I've got my own little obd reader and today another code as you say has appeared p0039 turbo bypass valve control circuit range / performance. This has never come up before not had any other work apart from the sensor as was pouring out oil. I've looked on the etis site as doesn't specify in my maintenance book when and it suggests 10years or 125k. Sounds a lot so it's never been done and it's on 60k and a 61 plate/2011. Also it's a 1.6 petrol ecoboost titanium x. Thanks.
