What is the lifespan of the turbocharger in Volkswagen's 1.4T engine?

[StSerenity]

Volkswagen's new 1.4T engine has a long lifespan, as the turbocharger in the EA111 1.4TSI engine features an independent cooling system. With regular maintenance, the turbocharger generally does not need replacement. Here is some relevant information about turbochargers: 1. A turbocharger is essentially an air compressor that increases intake air volume by compressing air. It utilizes the inertial force of exhaust gases from the engine to drive the turbine in the turbine housing, which in turn drives the coaxial impeller. The impeller then compresses air delivered from the air filter pipe, pressurizing it before it enters the cylinders. 2. When the engine speed increases, the exhaust gas velocity and turbine speed also rise synchronously, allowing the impeller to compress more air into the cylinders. The increased air pressure and density enable the combustion of more fuel.
