Sporadic surge blows
Surging of the turbocharger can occur during certain operating states, such as when reducing
the engine load quickly when manoeuvring. When this happens, the flow direction in the com-
pressor 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.
