Fergs22

Hi, I'm wondering if anyone has any tips for diagnosing the cause of this fault code. I've searched online through loads of posts and can't seem to get any further. Checked all vacuum lines which all seem fine, the actuator for the turbo has been replaced and calibrated, the egr is clear and not sticking, no split boost pipes. The car drives underpowered upto about 60mph, then goes into limp mode. It did have a fault for the swirl flaps but after fitting a blanking bracket that hasn't repeated (just waiting to get them mapped out) What could be causing this? Any advice is appreciated.
