Which outcome occurs when a turbocharged engine experiences wastegate actuator failure allowing pressure beyond design limits?

💡 Explanation

Compressor surge can occur because turbocharger overspeed creates excessive pressure and flow disruptions when the wastegate fails to divert excess exhaust gasses; therefore, surge results rather than optimized combustion because backflow limits performance.
