Have the cause clarified immediately by an ABB Turbocharging ser-
vice station and rectified.
Have components inspected for damage and, if necessary, replaced

Surging of the turbocharger can occur during certain operating conditions
such as when reducing the engine performance quickly when manoeu-
vring. At the same time, the flow direction in the compressor is momentari-
ly reversed. Such sporadic surge blows do not impair the safe operation of
the turbocharger.
A surge blow is accompanied by a loud bang and escape of hot air
from the filter silencer.
