Octy II 140tdi - Boost Pressure Regulation: Limit Exceeded (Overboost Condition)

Do you know if the vanes can be cleaned or do I have to buy a new turbo? I don't want to drive like a mad man just to clean the vanes by burning the dirt. This is a ridiculous ideea I think. ) There should be services where they can take the turbo off the car and clean it properly....

Edit: Oh, you were right about the injectors. I've done a scan yesterday and all the injectors are just fine, perfect!

I've never tried cleaning a turbo but some people have with good results. Perhaps give this a go:
