7 Troubleshooting / 7.4 Malfunctions when stopping
Sporadic surge blows
Surging of the turbocharger can occur during certain operating states, such as when redu-
cing the engine load quickly when manoeuvring. When this happens, the flow direction in the
compressor is momentarily reversed. Such sporadic surge blows do not impair the safe op-
eration of the turbocharger.
¡
A surge blow is accompanied by a loud bang and escape of hot air from the filter silencer.
