Is It Normal for the Jetta VS5 Turbocharger to Rust?

[DelBriella]

Jetta VS5 turbocharger rusting is a normal phenomenon. In relatively humid environments, slight rust marks may appear on the components, which falls within the normal range. Function of Turbocharging: The primary function is to increase the engine's air intake, thereby enhancing the engine's power and torque, making the vehicle more powerful. When a turbocharger is installed on an engine, its maximum power can increase by 40% or even more compared to when it is not equipped with a turbocharger. Usage Precautions: For turbocharged engines, there is an additional turbocharging system. The turbocharger is driven by exhaust gases, and compared to naturally aspirated engines where exhaust gases are directly released into the air, turbocharged engines have an additional heat source. During operation, the turbocharger housing can reach temperatures of over a thousand degrees, making the quality of the engine oil extremely important.
