What are the reasons for oil leakage in the Volkswagen Tiguan's turbocharger?

[OLena]

Volkswagen Tiguan's turbocharger oil leakage reasons are as follows: Aging of oil seal gasket: After years of driving, some parts of the car will inevitably age. If the gasket ages, it will cause oil leakage, in which case the gasket needs to be replaced. Poor lubrication inside the turbocharger: If there is poor lubrication inside the turbocharger, it can easily cause friction between components, leading to part wear and oil leakage. In this case, it is necessary to add engine oil or replace the worn parts. Turbocharger damage: If the car is involved in a collision that damages the turbocharger, oil leakage will certainly occur. In this situation, the turbocharger must be replaced directly.
