Diagnostic help
DTC limit lies between 25-50 kPa depending on fuel quantity and engine speed.
DTC indicates a mechanical fault in the turbo unit, air leakage between the turbo unit and intake manifold or in the vacuum system. There may also be a fault in the solenoid valve (boost pressure or swirl throttle).
Air leakage between the turbo unit and intake can cause the turbo unit to become damaged very quickly due to overrevving.
