What are the common issues with the Audi A3's turbocharger?

I have been experiencing some issues with my Audi A3's turbocharger and it's causing a loss of power. What could be causing this and how can I fix it?

First, make sure your turbocharger is properly lubricated to prevent any friction issues. You can also inspect the air filter and clean or replace it if needed. If these solutions don't work, it's possible that the turbocharger itself may need to be replaced.

I would recommend bringing your car to a trusted mechanic for a diagnosis. It could be a faulty wastegate, actuator, or a boost leak. They will have the proper tools and equipment to accurately identify and fix the issue.
