What are the common causes of turbocharger surging?

Turbocharger surging is a phenomenon that occurs when the flow of compressed air in the turbocharger is disrupted, leading to a pulsating or unstable power delivery. Several factors can contribute to this surging problem. One common cause is a mismatch between the turbocharger's size and the engine's needs. If the turbocharger is too big for the engine, it may struggle to deliver a continuous and steady supply of compressed air, resulting in surging. Another cause can be a restriction in the air intake or exhaust system, such as a clogged air filter or a blocked exhaust pipe, which hinders the smooth flow of air. Additionally, issues with the wastegate, such as incorrect adjustment or malfunctioning, can upset the balance between exhaust pressure and turbine speed, leading to surging. Maintaining proper maintenance and monitoring all these potential factors can help prevent turbocharger surging.
