Defect
In large touring buses, the variable-nozzle turbocharger fitted to the engine has turbine blades with insufficient strength. Resonance at high RPM can cause the turbine blades to fracture. Continued use after fracture results in white smoke and loss of power output, rendering the vehicle inoperable.
Corrective action
Replace the affected turbocharger on all vehicles with the corrected part and reprogram the control software.
