0.5 bar, it sounds as though it's in limp mode, so it could be any of your sensors to be honest, would get it on the select monitor if i was you

sorry scoobyboy just seen your post, great minds think alike!

It could be the arm on actuator come loose on the turbo so it will only run 0.5bar
Take heat shield off and see if arm is flapping about.
