p00af

Hi Guys Not had much luck with my 2016 Carvelle BiTdi... Had the EGR valve done with coil/engine management light coming on, did that 5 months a go... Now I have error code P0234 and P00AF - Overboost condition / boost controller A module performance. Its in a local garage and the guy is...

Has anyone had these fault codes pop up? I didn’t have any loss of power or any symptoms but happens every now and then after hard acceleration . Something to do with the turbo boost solenoid? Any help or advise would be gratefully accepted!
