Skoda Fabia 2006 1.4tdi gives the error in the picture.  vacuum hoses, turbo hoses checked.  valve block replaced.  injector done.  turbo was done.  but the problem is not solved.  I want help on this.

I will probably check with a skoda technician, it should be something there that is missed

I live in Turkey.  The same problem exists in more than one vehicle using this engine, although everything is checked, the reason is not found.

The VNT vanes are getting stuck long enough to create an intermittent fault, clean the mechanism and make sure it's moving freely.
