Checking Hoses And The Turbocharger (TC) Control Valve
Check particularly that the boost pressure sensor is correctly installed and has not come loose.
Check the intake system for air leakage. Check in particular the hose between the turbocharger (TC) and the throttle unit.
The boost pressure sensor is damaged if no fault is found in the above fault-tracing.
