MDE 4 Q10

Answer: A) A clogged air filter
C) An air leak in the intake system
D) A worn-out or damaged turbocharger turbine
E) A restricted exhaust system
Explanation: Poor turbocharger performance can be caused by several factors, including a clogged air filter that restricts airflow, an air leak in the intake system that allows compressed air to escape, a worn-out or damaged turbocharger turbine that affects its efficiency, and a restricted exhaust system that hinders the flow of exhaust gases.

Answer: A) Increased turbo lag and delayed acceleration
B) Excessive exhaust smoke or black smoke from the engine
D) Unusual whining or rattling noises from the turbocharger
F) Reduced power output and overall engine performance
Explanation: Indications of poor turbocharger performance can include increased turbo lag and delayed acceleration, excessive exhaust smoke or black smoke, unusual noises from the turbocharger, and reduced power output and engine performance. These symptoms often signal issues with the turbocharger or related components.
