Next time you are under the bonnet try disconnecting the little actuator arm on the front of the turbo that controls the vanes. You'll need a set of pointy noise pillars to pull off the little circlip and you can gently pull off the arm. Make sure there is no surface rust on the two surfaces. Mine was sticking here and then releasing the vanes, hence the overboost. A little bit of fine sandpaper and wd40 will clean it up. Good time to check your vanes open and close freely also. Mine never did it again, no matter how hard I tried to push it. I just regularly made sure it was clean.
Hope you get it sorted. Real pain when your climbing up a hill with a load on then need to pull over to get out of limp mode

The pin to control the vanes it connects to is on the exhaust side. If you are standing at the side of your car looking at the turbo and it will be right in the middle of it
