Sporadic surge blows
Surging of the turbocharger can occur during certain operating conditions
such as when reducing the engine performance quickly when
manoeuvring. At the same time, the flow direction in the compressor is
momentarily 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.
