hi, i am a garage owner had a skoda octavia mk2 2005 1.9tdi come in for a turbo to be checked, there is no boost, its had a turbo recon, new egr valve, new vacum box but still no boost

Does the vane actuator operate when you use output diagnostics?

actuator is not working, i cannot remember the exact fault one was altitude pressure sensor one was map sensor, but like i said its had a new map sensor.

Your vacuum system is probadly faulty. Check N75 valve and associated hoses.
